Bondable Magnet Wire, Bondable Copper Magnet Wire

General

Bondable magnet wire, also referred to as Selfbonding magnet wire, is film insulated wire ( GotoMagnet Wire Types ) which is coated with an additional bonding adhesive.

After activating the bondcoat, the individual turns of the coil are bonded together to produce self-supporting coils ("air coils" without bobbin) or special coils for later processing.

Use of bondable magnet wire offers advantages over conventional magnet wire in certain winding applications, eliminating the need for bobbins as well as taping or varnishing steps.

In many applications such as high-power speakers or small motors, bondable magnet wire can improve the performance and reliability. An important property of a bondable magnet wire is the thermal stability of the wound coil at higher temperatures. A thermoplastic bondcoat will become soft at higher temperatures and begin to lose its bond strength, but

could also be processed, for example, to form another shape of a coil and be rebonded at higher temperature. A thermoset bondcoat has higher heat resistant properties, so will lose its bond strength only at a temperature that will destroy the enamel.

Because of the additional application of a bondcoat, selfbonding magnet wire is more expensive than normal wires, which is offset by the value added.

Activation of the bondcoat may be achieved with either heat, or in some cases a solvent, or a combination of the two ( Goto Bonding Processes ).

Our Product Line

Elektrisola produces bondable magnet wire with diameters of 0.010 - 0.50 mm ( Goto Technical Data by Size ). In addition to copper as a conductor material, other alloys are available, such as Aluminium or Copper Clad Aluminium for light weight coils or high tensile strength conductors for better durability ( Goto Metals ).


CCAW with bondcoat

Selfbonding magnet wire types can be differentiated by the chemical basis of their coatings, primarily by their thermal properties, by their technical properties and by the preferred bonding method.

The basic bondable magnet wire types offered around the world have differences mainly explained by the history of their development. Therefore Elektrisola offers selfbonding magnet wire types for the 3 major continents
( Goto Selfbonding Wire Types ). In Asia, special high performance bondcoats formulated for use in specific Asian applications are also offered ( Goto High Performance Selfbonding Wire Types ).

In addition to standard selfbonding enamel types, ELEKTRISOLA has its own certified selfbonding enamel development for special applications. For example, in fine wire sizes, specialized ultra-high temperature selfbonding enamel types are now available, which can be wound with automated hot-air winding machines for fast and cost effective processing providing a major advantage to Elektrisola customers.

Production Process

The production process of a selfbonding magnet wire is similar to a normal film insulated wire

( Goto Enamelling Process ), but needs 2 enamel applicators, one for the electrical insulation coating, and one for the bondcoat.

Bonding Process

The bondcoat adhesive on the outside of the bondable magnet wire can be activated by heat or with chemicals. These bonding methods are described below.


Heat/Thermal Bonding:

All Elektrisola bondcoats can be activated by heat, either by directing hot air on to the wire during winding, by oven-heating of the wound coil, or by applying electric current to the wound coil after the winding cycle is completed. In any of these examples, the principle is to heat the winding slightly above the bondcoat’s melting temperature in order to activate the bondcoat and bond the wires together.


Hot-air Bonding during winding has the advantage of eliminating the secondary bonding operation. This method is cost effective and primarily used for wire sizes thinner than 0.200 mm. This method became much more popular over the last few years following the development of ultra-high temperature selfbonding enamel types.


Hot air winding


Oven Bonding is accomplished by heating the wound coil, which still remains on a fixture or tooling, in an oven at a suitable temperature and time sufficient to obtain uniform heating throughout the winding followed by a cooling cycle. Heating time is generally 10 to 30 minutes, depending on the size of the coil. Disadvantages of oven bonding are the longer bonding time, additional process steps, as well as the potential need for many winding fixtures.

Resistance Bonding is accomplished by applying electric current to the finished coil to electrically heat it by resistance to the proper bond temperature. Bonding voltage and time are dependent upon wire size and coil design, and therefore will need to be developed experimentally for each specific application. This method has the advantages of being quick and generating a quite uniform heat distribution. It is typically used for wire sizes thicker than 0.200 mm.


Solvent Bonding:

Some bondcoats can be activated by applying specified solvents during the coil winding process. Application of the solvent, usually via a saturated felt during winding ("Wet Winding"), causes the bondcoat to become very soft. This process requires the use of a fixture to hold the coil in place while the solvent is drying and the wires stick together. Afterwards, the coil should be heated in an oven cycle to evaporate any residual solvent, which, if left within the coil, might cause long-term coil failure, as well as to complete the adhesive curing process for optimum bond strength.

  • Reduced total cycle times
  • Improved performance
  • Low environmental impact

Magnet wire, Magnet Copper Wire

General

Magnet wire is a metallic conductor insulated with a varnish and generally used for electrical applications. Most times magnet wire is wound in different shapes of coils to generate magnetic force for motors, transformers, magnets etc. Elektrisola produces over 30,000 different types of magnet wire with the most important differences of characteristics as follows:


Conductor Material for Magnet Wire

Copper is the standard used conductor material with excellent conductivity and very good windability. For low weight and larger diameters Aluminum sometimes can be used as a conductor material for magnet wire. Because of the difficult contacting of Aluminum wire with problems of oxidation Copper Clad Aluminum can help to compromise between Copper and Aluminum. For special applications a wide variety of conductor materials is offered, such as Brass, Silver, Nickel, Gold, Stainless Steel, or alloys of copper for special characteristics like higher mechanical strength or bending performance. In addition, the core conductors can be plated with different materials such as Silver or Nickel.

Magnet wire metals

Bare Wire Diameter Range

Elektrisola specializes in fine magnet wire diameters, starting with 0.008 mm (8 microns), and going up to a diameter of 0.50 mm. Beside the standardized diameters a big variety of special diameters is produced according to customer’s specification. Bare wire tolerances are very important in magnet wire as they have direct impact on the resistance what again determines the variance of the final coil resistance.

Outer Diameter of Magnet Wire

International standards like IEC group magnet wires according to ranges of specific outer diameters. IEC groups the insulation in Grade 1, 2, or 3, NEMA in single, heavy, or triple, and JIS in class 0, 1, 2, or 3. The tolerances in these standards can be further restricted if necessary to design and optimize the wound coils and final products.

Selfbonding Layer

In addition to the base coat insulations described separately, a selfbonding layer can be applied to the magnet wire, by which the wire will be bonded together for example for bobbinless coils, such as voice coils.

Spool Types for Magnet Wire

Spool types have to fit to the wire size. Finer magnet wire sizes are wound on smaller spools, while for heavy sizes very large spools can be used. They are important for productivity as larger spools require less spool changes on the winding machines.

Magnet Wire Spools & Packaging

The wire length on one spool can be very long:

0.018 mm on spool 99L: up to 417 km of magnet wire
0.05 mm on spool 199L: up to 1143 km of magnet wire
0.30 mm on spool 400/630: up to 277 km of magnet wire

Insulation Types for Magnet Wire

Elektrisola offers a wide range of different insulations. Polyurethane has the advantage of easy direct contacting by soldering, while Polyester insulations are more resistant against higher temperatures. Thin top coats as Nylon or Polyamidimide may improve certain desired characteristics like mechanical or chemical strength of the magnet wire.


Magnet Wire Colors

Colors may be used to differentiate magnet wire types or diameters, but have the disadvantage of lower technical properties and higher costs.

Lubrication for Magnet Wire

A defined very low amount of lubrication – mostly special types of paraffin – is applied to achieve excellent windability of the magnet wire in all winding processes without wire breaks.

Our Product Line of magnet wire

Elektrisola specializes in fine magnet wire diameter and offers a wide range of products from 0.008 mm (8 microns) to 0.50 mm with many different enamel types on different conductor materials.

Specifications for Magnet Wire

Elektrisola produces magnet wires according to many different specifications. The most important worldwide used specification is IEC, besides NEMA in North America and JIS in Asia.

 Technical Data by Size for Magnet Wire

Enamel Types for Magnet Wire

Polyurethane
is a varnish which is easy for direct contacting by soldering, welding or crimping. Especially for fine magnet wire the easy soldering is the most advantage of this enamel type. Polyurethanes are available with Temperature Index 155 °C (Polysol© 155) and Temperature Index of 180 °C (Polysol© 180). This enamel is available from 0.008 to 0.50 mm on all of our conductor materials.

Polyesterimides
are more resistant against higher temperatures and beside the pure Polyesterimide (Estersol© 180) not usable for direct soldering. Under this enamel type also Theic-modified Polyesterimide (Amidester© 200) or (Amidester© 210) are listed.

Polyamidimides and Polyimides
have the highest temperature and chemical resistance and you will find them as I220-magnet wire or ML240©-magnet wire at ELEKTRISOLA product portfolio.

 Enamel Wire Types

Based on the above mentioned enamel types, you can combine all these enamels with a self bonding coat such as Polyvinylbutyral, Polyamide or Polyester.

Bonding Methods

Production Process for magnet wire

Drawing process

For copper wires an 8 mm copper rod (5/16″ in USA) is used as raw material, which is drawn through drawing dies to the required bare wire dimension in several stages. The copper rod has to be of high purity and consistenly high quality to manufacture fine and ultrafine wires of sizes below 10 µm. ELEKTRISOLA uses only pure electrolytic copper ETP1 (copper content min. 99.99 %) from pre-approved high quality vendors.


The drawing process is carried out sequentially through several groups of machines producing specific diameter ranges. The wire is elongated in several stages through dies, so that the larger wire is permanently becoming thinner and longer during the drawing process while the volume remains unchanged.


Multiple drawing with cones
Multiple drawing with cones

The quality of the copper, the fine tuning between the different drawing stages, and especially the quality of the drawing dies, are all of high importance to achieve a high quality final bare wire. The bearing surfxes of the wire drawing dies consist of natural or artificial diamonds or, for heavy wire production, of carbide.

Enamelling Process for Magnet Wire

All magnet wires are magnet on special enamelling machines which are developed and produced by ELEKTRISOLA for our exclusive use. Enamelling is a continuous process, mainly consisting of the annealing process, enamel application, curing process, lubricant application, tension control and spooling.


1. Annealing Process
During the drawing process the bare wire’s grain structure has been changed through cold deformation. Annealing will re-crystalize the copper and make it soft again. This thermal stress relief process is carried out under protective atmosphere in order to avoid oxidizing the wire surface, which would interfere with good adherence of the initial coating of insulation later in the process. Softness of the magnet wire is an important criteria for good windability, in particular significantly reducing the number of wire breaks.

2. Enamel Application
There are 2 main application systems for enamelling of winding Magnet wires, i.e felt application and die application, whereas felt application is mainly used in fine magnet wire production, while die application is mainly used in heavy magnet wire production. The enamel coating should always be applied in as many single layers as possible rather than fewer and thicker layers to achieve better mechanical and electrical properties.

3. Curing Oven
Solvents contained in the liquid enamel are driven out in the curing oven at high Temperature and then are burnt catalytically by using the thermal energy in an environmentally friendly way. Temperature control is very important: if the temperature is too low, too many solvent residues will be left in the enamel layer, leading to poor adhesion and reduced mechanical and electrical properties of the magnet wire. If the temperature is too high, the enamel coating will be hard and brittle, leading to cracks in the insulation coating  resulting from mechanical stress.

4. Lubrication
A defined amount of lubricant is precisely applied to the insulated magnet wires surface. Lubrication is necessary to achieve consistent winding properties and failure-free winding of the wire even at high winding speeds.

5. Diameter Control
ELEKTRISOLA continuously monitors the Outer Diameter of all magnet wires after the final pass by laser.

6. Tension Control
A continuous wire tension control during the enamelling process results in a consistently uniform spooling onto the spool. With effective tension control, elongation of the magnet wire is avoided and thus a change in resistance. Furthermore, good de-reeling properties for customer can be guaranteed.

7. Spooling
The wire pitch and the spool’s rotational speed are spooling process variables closely to be controlled. This results in consistently good magnet wire de-reeling performance and minimizes other problems like trapped and tangled wires.

8. Monitor
The monitor informs the operator about all important parameters of the process.

Spools/Packaging

Spools and Packaging for MAGNET Wire

General

Magnet wire is wound on spools of different sizes and shapes. The wire diameter determines the spool size which can be used. Ultrafine wire typically is produced on smaller spools while heavy wire is wound on very large spools.

Different global standards specify different spool types which are typically associated with each continents standard.

Bondable magnet wire types

bondABLE MAGNET Wire Types

General

There is a large variety of bondable magnet wire types available. The different base coats and self bonding overcoats are described in different standards, such as IEC 60317, NEMA MW 1000 or JIS C3202, which sometimes utilize different test methods.

Under the respective standard the typical technical values are given for the different base coats such as Polyurethane, Polyester, Polyesterimide etc. and for different bond coats such as Polyvinylbutyral, Polyamide etc.

For easier comparison of products and the evaluation of their suitability for certain applications, there is a check box below each of the product-codes and a "Compare Selected Items" button in the precolumn of the table. When this button is clicked, only the marked items appear side by side.  This view of the table is also suitable for printing; to use the options of your browser for this purpose, please use the "Show all" button to make the invisible products reappear again.

Thermal Stability in Hours [h] vs. Temperature in Degrees Celsius [°C]
Average breakdown voltage at 20°C
Calculation of average value Ds
Ds=t*Vµ(volt), with
Ds : breakdown voltage
t : increase with insulation, t = da - dnom, with
da : outer diameter
dnom : bare wire diameter
Vµ : Volt per micron insulation
Example
Test with cylindrical electrode
dnom = 0.071mm (41 AWG)
da = 0.083mm
t = da - dnom = 0.083 - 0.071 = 0.012mm = 12 µm
Vµ = 220 V/µm, therefore
Ds = 12µ * 220 V/µ = 2,640 V

Breakdown Voltage (BDV)

Fully Insulated Wire

Breakdown Voltage Calculation acc. to FIW Standard IEC 60317-0-7

Test is done by cylinder BDV test acc. to IEC 60851-4.3.2. The minimum breakdown voltage has to be calculated for every specific FIW wire size using the increase by insulation and the specific V/µm-value from below table.

Nominal conductor diameter
mm
Minimum specific breakdown voltage
V/µm increase
over up to and including at room temperature at 180°C
- - >0.100 81 56
0.100 0.355 76 53
0.355 0.500 70 49
0.500 1.000 53 37
1.000 1.600 47 33

NOTE: The specific breakdown voltage is the result of the quotient of the measured value and enamel increase.

Example of formula for calculation of breakdown voltage (BDV):

BDV = min. increase *min. spec. BDV in V/μm

Example: 0.2 mm FIW6 with min. OD 0.303 mm

min. increase = min. OD - nom. dia. = 0.303 mm - 0.2 mm = 0.103 mm = 103 μm

=> BDV = 103 μm x 76 V/μm = 7828 V

Comments on different BDV standards

  • The actual version of the Transformer Standard IEC 61558-1 gives much lower values than IEC 60317-0-7.
  • The specific voltage per micron is given acc. to IEC 60317-0-7 at room temperature, while IEC 61558 calculates values of 180 °C and a safety margin (0.85). Actually needed temperature of SMPS (Switch Mode Power Supply) is somewhere in between.
  • IEC 62368 follows the BDV values of IEC 61558, but does not specify 180 °C as test temperature as IEC 61558.

History

History of ELEKTRISOLA

1948
Foundation of Elektrisola in Germany
Founder
Dr. Gerd Schildbach
1948

First building in Eckenhagen,
Germany
1949
Elektrisola was founded by Dr. Gerd Schildbach on July 1, 1948 in Eckenhagen, Germany. His father, Dr. Ing. Richard Schildbach, was already producing fine resistance wires and held the world record in drawing the finest wire (0.008 mm) in 1938. Based on this wire drawing knowledge, Dr. Gerd Schildbach started to design and build his own fine wire enameling machines. This internally developed process technology later became a major contributor to the rapid growth of the Elektrisola fine wire production worldwide.
1961
Italy: The first factory outside Germany
Elektrisola Atesina I, Molini di Tures, Italy
Rapid sales growth in new markets required construction of additional production capacity. Elektrisola Atesina was built in the Alps mountains in the German speaking part of northern Italy and started production in 1964.
1968
First factory in EFTA economic area
Elektrisola Feindraht AG, Escholzmatt, Switzerland
Between 1957 and 1960, Europe had been divided into 2 different blocks, EWG (Belgium, France, Germany, Italy, Luxemburg and The Netherlands), which became EU in 1993, and EFTA (Austria, Denmark, Great Britain, Norway, Portugal, Sweden, Switzerland), with duties levied for trading between those blocks. In order to serve customers in the EFTA zone, Elektrisola Feindraht, Switzerland, was founded in 1968.
1970
Wire drawing factory in Italy
Elektrisola Atesina II, Lutago, Italy
Rapid expansion of the Italian Atesina plant required construction of a second plant 15 km away from the original factory to have better access to workers close by. In 1973 this new factory opened its doors, specializing in bare wire production.
1976
First factory outside Europe
Elektrisola Inc., Boscawen, NH, U.S.A.
Elektrisola began exporting fine wire to the US market in the 1960’s. Due to the continued growth of this newest market the decision was made to build a new fine wire plant in the United States. In 1976 Elektrisola Inc. was opened in Boscawen, NH and continued to expand into the largest fine wire factory in North America.
1984
First sales company of Asia
Sales to Asia became a new challenge in the 1980’s. Therefore a trading company, Elektrisola Hong Kong Ltd., was founded in Hong Kong in 1984.
1993
First factory of Asia
Elektrisola (Malaysia) Sdn. Bhd., Bentong, Malaysia
To support the fast growing Asian market with local production, Elektrisola (Malaysia) was built and began operations in 1993 near Bentong, Malaysia.
1993
Generation change in Management
Dr. Detlef, Dr. Gerd and Dr. Oliver Schildbach
Dr. Gerd Schildbach passes the management of the Elektrisola Group on to his sons, Dr. Detlef and Dr. Oliver Schildbach.
1994
Sales office in Japan
The Japanese fine wire market was one of the most important in the world. Sales and Technical support was required locally in Japan to represent the other Elektrisola plants worldwide. Therefore, Nippon Elektrisola was established in 1994 as a trading company to serve the Japanese market.
1995
Expansion in North America with a factory in Mexico
Elektrisola S.A. de C.V., Cuauhtémoc, Mexico
