What is the Role of the Insulating Material Powder Mica Tape?

What is the role of the insulating material powder mica tape and other insulation materials of the geared motor?
At present, in China, epoxy tung oil anhydride insulating material powder mica tape is widely used in place of the above-mentioned sheet mica tape for ground insulation of high-voltage motor coils. This mica tape is made of powder mica paper, epoxy tung oil anhydride adhesive and glass cloth.

In addition to the above insulating material powder mica tape, there are also soft mica plates, mica foils, shaped mica plates, commutator mica plates, and the like. With the same volume (or weight), the output power of the motor will increase by about 10% to 15% each time the insulation system of the geared motor rises. The history and experience of the development of foreign traction motors show that the use of new insulation materials and structures and advanced insulation technology is one of the important ways to improve the technical and economic indicators and operational reliability of motors. The insulating material powder mica tape can be said that the development of traction motors is to a large extent It depends on the progress of the insulation system.
