Abstract

The invention discloses a fan startup method and device. The fan startup method includes the steps: the rotating speed of a rotor of a motor is detected, and the rotor drives the rotating of blades ofthe fan when rotating; when the rotating speed of the rotor is lower than a first speed threshold value, the rotor can be controlled to stop at the position corresponding to the preset angle in a mode of locking; after obtaining the startup instruction of the fan, the rotor can be controlled to start from the position to enable the fan to start. In the technical scheme, the step of detecting therotor position of the motor before starting the fan is omitted and the purpose of quickly starting the fan can be achieved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a fan starting method, device and computer storage medium. Background technique [0002] An important means of saving electric energy in contemporary society is to adopt motor frequency conversion speed regulation technology. The same is true in the field of fans. Ordinary fans are gradually replaced by frequency conversion fans sampling permanent magnet synchronous motors. The permanent magnet synchronous motor needs to detect the rotor position of the motor before starting. However, during the positioning and starting process of the variable frequency fan, the blades are easy to swing back and forth, which is not easy to locate the rotor of the motor. [0003] The method of starting the fan in the prior art generally detects the position of the rotor of the motor before starting, and then starts after determining the position of the rotor of the motor. However, it takes a certain...
