The present disclosure discloses a method for braking a permanent magnet synchronous motor and a related device. The method is applied to an electronic speed controller and includes: receiving a signal for braking the permanent magnet synchronous motor sent by a flight controller; sending a first control signal to the permanent magnet synchronous motor, the first control signal being used to control the permanent magnet synchronous motor to decrease its rotational speed to a preset rotational speed range within a first preset time period; and after the first preset time period ends, sending a second control signal to the permanent magnet synchronous motor, the second control signal being used to control the permanent magnet synchronous motor to stop rotating within a second preset time period. According to the method, consistency of shutdown of multiple motors is ensured, and use experience of a drone is improved.
