How should the protection circuit be designed in motor controller PCB assembly?

In the motor controller PCB assembly, the design of the protection circuit is very important, which can ensure the safety and stability of the controller during normal operation. Here are some suggestions for designing protection circuits:

1. Reasonable use of multi-layer boards: In the design of multi-layer boards, the inner layer can be used to design protection circuits, such as over-current, over-voltage, under-current, under-voltage and other protection circuits. These protection circuits can comprehensively protect the entire system without affecting the normal operation of other circuits.
