Abstract

The invention discloses a method and device for controlling the rotating speed of an air conditioner motor, a storage medium and a processor. The method comprises the steps that a feedback signal of an air conditioner motor is received, the feedback signal carrying the motor feedback pulse number of the air conditioner motor; determining the current motor rotating speed of the air conditioner motor based on the motor feedback pulse number; and if detecting that the current motor rotating speed is not equal to the target motor rotating speed, controlling the air conditioner motor to adjust the current output pulse duty ratio, and circularly and continuously obtaining the current motor rotating speed of the air conditioner motor till detecting that the current motor rotating speed is equal to the target motor rotating speed. The technical problems that in the prior art, air conditioner motor rotating speed adjustment is too fast, noise is caused, and performance indexes of an air conditioner system are affected by too slow motor rotating speed adjustment are solved.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a method and device for controlling the rotational speed of an air conditioner motor, a storage medium and a processor. Background technique [0002] With the diversification of air conditioner motors, many of the air conditioner internal units currently use AC PG motors or DC DC motors. The main controller controls the motor speed by outputting PWM pulses. This motor control is closed-loop control. According to the target speed and actual speed difference to adjust the output of the motor. [0003] However, the adjustment rate of the motor speed of the air conditioner directly affects the user's experience of using the air conditioner. If the motor speed is adjusted too fast, it will easily cause noise problems. If the motor speed is adjusted too slowly, it will affect the performance indicators of the air conditioning system. [0004] For the above problems, no effective solution ...
