Abstract: Embodiments of the present disclosure relate to the technical field of electronic devices, and a method for generating a motor brake signal is disclosed. In the present disclosure, the method for generating a motor brake signal includes the following steps: S1: controlling a motor by using different brake signals respectively to obtain vibration margins of the motor corresponding to the brake signals; and S2: selecting, from the brake signals, a brake signal with superior performance as the motor brake signal based on the vibration margins of the motor, wherein the smaller the vibration margin of the motor is, the more superior performance the corresponding brake signal has. The present disclosure further provides an apparatus for generating a motor brake signal. The method and the apparatus for generating a motor brake signal that are provided in the present disclosure enable the motor to have a good brake effect.
