Electric machine controller

1.Introduction of product function

l  MCU is short for Motor Control Unit, namely, the motor controller, which is the control center of the entire power system. It can control IGBT by receiving command of VCU or HCU, or receiving the controller internal sensor signal and motor feedback speed signal, thus realizing the control over the motor.

l  GCU is short for Generator Control Unit, namely, the generator controller, which is the control center of the entire power system. It can control IGBT by receiving command of VCU or HCU, or receiving the controller internal sensor signal and motor feedback speed signal, thus realizing the charging function.
