Abstract
An electronic device includes a signal trigger circuit, a flat-motor drive circuit, and a flat motor. The signal trigger circuit sends a starting instruction to the flat-motor drive circuit for instructing to start the flat motor. A processor of the flat-motor drive circuit sends a first triggering instruction to a voltage processing circuit of the flat-motor drive circuit after receiving the starting instruction. The voltage processing circuit provides a first working voltage Vto the flat motor after receiving the first triggering instruction, and provides a second working voltage Vto the flat motor after a first time period. V<V≤V, Vis a rated voltage value of the flat motor, and Vis a maximum forward voltage value that the flat motor can bear when the flat motor is started.
