Menene abubuwan da aka saba amfani da su don insulating don motoci

Insulating materials are materials that are non-conducting under allowable voltage, but not absolutely non-conducting materials. Under the action of a certain external electric field strength, conduction, polarization, loss, breakdown and other processes will also occur, and long-term use will also occur Ageing. The resistivity of this product is very high, usually in the range of 1010～1022Ω·m. For example, in a motor, the insulating material around the conductor isolates the turns and the grounded stator core to ensure the safe operation of the motor.
