Title:
CONTROL METHOD AND SYSTEM FOR ROTATION SPEED OF DIRECT-CURRENT BRUSHED MOTOR, STORAGE MEDIUM, AND BLOWER
Document Type and Number:
WIPO Patent Application WO/2022/222682
Kind Code:
A1
Abstract:
Provided in the present invention is a control method for a rotation speed of a direct-current brushed motor. The method comprises: setting a control period of a motor in a control circuit of a blower; and configuring the number of motor-conducted half-waves in several alternating-current half-waves, so as to control a power supply voltage of the motor in the control circuit. Provided in the present invention are a control system for a rotation speed of a direct-current brushed motor, a storage medium, and a blower. The control method in the present invention comprises: setting a control period of a motor in a control circuit of a blower, and configuring the number of motor-conducted half-waves in the control period, so as to control a power supply voltage of the motor. By means of the control method, the blower maintains a relatively constant rotation speed at different mains supply voltages, thereby improving the stability of the rotation speed of the blower, reducing noise that is generated during the operation of the blower, and prolonging the service life of the blower.
