Generation and Harm of Corona in High Voltage Motors
source：未知 time：2024-11-18 09:17nbsp; click：
Compared with low-voltage motors, the production of high-voltage motor coils is very complicated. The stator windings of high-voltage motors will select different electromagnetic wires according to different rated voltages. During the coil production, anti-corona materials will be wrapped on the straight edges of the coils and the positions extending from the slots, which are what we call high and low resistance bands. The purpose is to prevent the generation of corona during the operation of the motor.
