The invention discloses a control method and system of a stepping motor and an air conditioner. The control method of the stepping motor comprises the following steps that in the synchronous working process of the N stepping motors, the lowest action time of the N stepping motors at the respective current rotating speeds to complete one-beat action and the preset working time at the current rotating speeds are acquired, wherein N is larger than 1; the stepping motors with the lowest action time smaller than the preset working time of each beat of the stepping motors in the N stepping motors are determined; and at least one stepping motor is selected from the determined stepping motors, and driving energy is provided for driving the stepping motor according to the lowest action time corresponding to the stepping motor so as to complete action of each beat. According to the control method, the problems that all-voltage driving is adopted at any rotating speed of the stepping motor, so that the power consumption of a driving circuit is increased, energy saving is not facilitated, heating of the stepping motor is caused, and the total heating amount of the circuit is increased to influence the service life of devices in the circuit are solved.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a control method, system and air conditioner for a stepping motor. Background technique [0002] Stepper motor is one of the important components of household appliances. After the drive pulse of the stepper motor is fixed in its driving mode, the time of one pulse is usually fixed, which makes each beat no matter how long it is driven by full voltage. . [0003] This driving method increases the power consumption of the driving circuit, especially in household appliances with several built-in stepping motors, the total amount of energy wasted by multiple stepping motors is huge, and it is easy to cause the heating of each stepping motor, which increases the circuit The total amount of heat generated affects the life of the devices in the circuit. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide a control method, system and...
