Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0043] In practical applications, the brushless DC motor is affected by factors of operating conditions, which will cause the speed to change, thereby affecting the air volume. For example, if there is frost on the external unit of the air conditioner, it will affect the overall operation of the motor and cause changes in the air volume. The air volume is a key performance indicator for evaluating motors. A stable air volume will enable the entire motor system ...

The invention relates to the technical field of motor control, in particular to a motor control method, device and equipment, a motor and electrical equipment, and the method comprises the steps: detecting the rotating speed information of the motor, generating a rotating speed sawtooth wave signal based on the rotating speed information of the motor, fusing the rotating speed sawtooth wave signal with an initial VSP speed regulation signal, and generating a rotating speed control signal. And controlling the motor to operate according to the rotating speed control signal. According to the technical scheme, the rotating speed of the motor is monitored in real time in the load changing process, the rotating speed control signal is generated according to the rotating speed change of the motor, and therefore the rotating speed of the motor is controlled, stable running of the rotating speed of the motor is guaranteed, stable output of air volume is maintained, real-time sampling of voltage and current is not needed, and the control mode is simple; the occupied resources of the single-chip microcomputer are few, and the processing speed of the single-chip microcomputer is ensured.
Description
technical field [0001] The invention relates to the technical field of motor control, in particular to a motor control method, a control device, a control device, a motor and electrical equipment. Background technique [0002] The brushless DC motor is mainly composed of a motor body, a controller, and a sensor. It has the characteristics of large starting torque, good speed regulation performance, and high efficiency. It is widely used in electrical products such as air conditioning systems and air purifiers. [0003] In practical applications, the brushless DC motor is affected by factors of operating conditions, which will cause the speed to change, thereby affecting the air volume. For example, if there is frost on the external unit of the air conditioner, it will affect the overall operation of the motor and cause changes in the air volume. The air volume is a key performance indicator for evaluating motors. A stable air volume will enable the entire motor system to ac...
