Home Appliance Motor Commutator Car Motor Colectors Collector
Application:
The insulaiton materials are mainly used as a slot liner,slot closure,phase and turn-to-turn insulation in
low or medium voltage electrical motors.
Besides it is also used as interlayer insulation in transformers and other electrical appliances.
The insulation cell such as DMD, NMN,PMP, ect kinds of motor slot insulation,before cuffing creasing
forming and cutting machine turn them into slot cell, insulation paper pass the testing of
thickness,tolerance,tensile strength,breakdown voltage, bonding (adhesive) property in heating status
150±2℃/10min,
with good quality, Usually used as slot liner,slot closure,phase and turn-to-turn insulation.
The insulation class defines what kind of material is being used according to temperature operation.
Standard motors are manufactured according to Isolation B.
For the insulation class and temperature, please refer to below table:
| Insulation Class | A | E | B | F | H |
| Max Tem(℃) | 105 | 120 | 130 | 155 | 180 |
| Winding rise Tem(K) | 60 | 75 | 80 | 100 | 125 |
| Performance(℃) | 80 | 95 | 100 | 120 | 145 |
Insulation class A E B F H
Max Tem(℃) 105 120 130 155 180
Winding rise Tem(K) 60 75 80 100 125
Performance(℃) 80 95 100 120 145
For example, when customer use insulation paper (polyester) DMD,PMP or other insulation material such
as powder, varnish they could consider the motor's insulation class accordingly.
Covering pumps,compressor,dries,exhausters,transporters,mixers,grinder,mills,fan and other kinds of
motors.
Below is the test report the DMD paper:
