I want to ask why this motor cannot start? The voltage from B+ to B- is normal, but after starting, the voltage from B+ to M- jumps and the motor vibrates.

Insufficient information to judge. First, set the driver board to the full-open output state, that is, the motor runs at full speed in one direction, and then test and analyze from the output step by step.

Describe the problem clearly and provide a schematic diagram.

It's really not explained clearly.

It is difficult to determine whether the motor vibration is a circuit control problem or a mechanical problem of the motor.

There is really too little information

At least provide a schematic diagram or motor drive solution introduction

However, you can directly connect the motor to B+B to see if it is a motor problem or a driver problem.

Without the schematic diagram, if B- and M- are short-circuited, the motor will turn to normal
