AI Technical Summary
Existing motor controllers have low EMC filtering structure integration and large space occupation, which makes them susceptible to interference when controlling a single motor, reducing control accuracy and increasing cost.
An EMC filter magnetic ring structure with two sets of magnetic ring mounting units was designed, corresponding to two sets of motors respectively. Filtering is performed through independent magnetic rings and connecting components to ensure independent control of each motor, reduce mutual interference, and achieve electrical connection through copper busbars and terminals.
This improves the control accuracy of the motor controller, reduces production and usage costs, and ensures the stable operation and reliability of the motor.
