A power module
The theme of the motor controller is an inverter that controls the current and voltage of the motor. The commonly used power equipment mainly includes MOSFETs, GTOs, IGBTs, etc.
B drive control module
Convert the commands from the central control module into on/off commands for the thyristor in the inverter, and use it as a maintenance device with monitoring and maintenance functions for overvoltage, overcurrent, and other faults.
C center control module
Including PWM wave generation circuit, reset circuit, sensor signal processing circuit, and interaction circuit. The central control module receives commands and status information of other components on the vehicle through external interfaces. Internally, transmit the translated instructions to the inverter drive circuit and detect the control effect
D sensor
The sensors applied to the system include current sensors, voltage sensors, temperature sensors, motor shaft angle and orientation sensors, etc., which can be added or removed according to planning requirements.
