Motor Control Unit

The main products of our new energy commercial electric motor control unit system are: main drive motor controller 3-in-1 drive motor controller (main drive + DC/DC + power distribution). We design electric commercial vehicle system solutions to meet the needs of different vehicle models. The integrated electric motor controller system can effectively help OEMs to optimize the whole vehicle system design and reduce the material cost and production cost of the whole vehicle.

Components of Motor Control Unit MCU

The electric motor control unit consists of an inverter and a controller. Among them, the inverter receives the DC power delivered by the battery and converts it into three-phase AC power to power the car motor. Next, the electric motor controller receives signals such as motor speed and feeds them back to the instrument. When braking or acceleration occurs, the frequency of the electric motor controller increases or decreases, thus achieving acceleration or deceleration.

Applications of Motor Control Units MCU

The role function of electric motor control unit:

(1) energy conversion function. Realize braking energy recovery to improve vehicle range;

(2) Torque execution function. The controller sends negative torque values to the motor controller to reduce energy waste;

(3) active discharge function. Large-capacity capacitor self-discharge for a long time will have high-voltage safety risks;

(4) safety protection function. Motor system with fault detection, fault reminding, fault handling and other safety protection functions;

(5) high-speed CAN network communication function. Effective realization of the electric motor control unit and the whole vehicle function strategy, control the safe and reliable operation of the motor system to ensure the safe operation of the vehicle.
