Enamelled Wire Types

General

There is a big variety of enamelled wire types available. The different insulations are described in different standards, such as IEC 60317 (Asia or Europe), NEMA MW 1000 (USA) and JIS C 3202 (Japan) which sometimes still use different test methods.

For NEMA MW 1000C values are given in inch and metric.

Under the respective standard (customized to the region where appropriate), the typical technical values are given for the different insulation, such as Polyurethane, Polyester, Polyesterimide, Polyimide.

Thermal Stability acc. to IEC 60172

The line chart below is for technical comparison only and cannot be used to forecast lifetime of wound products (see also IEC 60172)



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

The line chart below is for technical comparison only and cannot be used to forecast lifetime of wound products (see also IEC 60172)



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

Calculation of Breakdown Voltage (Test acc. to IEC 60851.5.4.2, cylinder) The Breakdown voltage depends mainly on the thickness of the insulation (see formula), but also on the bare wire diameter, the application temperature of the coil and the type of enamel.

Thermal Stability in Hours [h] vs. Temperature in Degrees Celsius [°C] or Fahrenheit [°F]
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
