Problems solved by technology

However, when a single motor makes sound, it is difficult for users to hear the prompt sound from the motor because the sound performance of the motor itself cannot meet the sound standards of professional equipment such as buzzers or loudspeakers.
If multiple motors are used to sound at the same time, it is difficult to distinguish which motor is faulty

Abstract

A control method for a motor, comprising: acquiring a pre-set sounding sequence of a plurality of motors (200A, 200B, 200C, 200D); according to the pre-set sounding sequence, controlling the sounding of the plurality of motors (200A, 200B, 200C, 200D), so as to form a combined sound. The method can aesthetically improve the sound of the motor, and also can easily determine which motor control link has failed.

Description

technical field [0001] The invention relates to a control method of a motor, in particular to a control method and system for controlling the sound generation of multiple motors. Background technique [0002] A motor is a common power device used to output power to a mobile platform. For example, an unmanned aerial vehicle uses a motor to provide flight power. [0003] Existing mobile platforms like to use a motor as a generating device for the prompt sound. However, when a single motor emits sound, it is difficult for users to hear the prompt sound from the motor because the motor itself is not capable of expressing sound to the standard of professional equipment such as buzzers or loudspeakers. If multiple motors are used to sound at the same time, it is difficult to distinguish which motor breaks down. Contents of the invention [0004] In view of this, it is necessary for the present invention to provide a motor control method and a control system that can improve th...
