The insulation requirements between the commutating segments of a DC motor are:

1.Heat resistant and fire resistant.

2.It is resistant to moisture.

3.It can be wear-resistant and flexible enough mechanical strength.

4.The coefficient of thermal expansion should be small.

5.Good insulation.

As Mica Powder materials meets the above requirements, it is used as an insulating material. We are Non-metallic Mineral Products Manufacturer and supplier in China. Welcome to contact us for more information.
