Abstract

The embodiment of the invention discloses a starting method and device of a brushless direct current motor, a storage medium and electronic equipment, and belongs to the field of motor control. Before the brushless direct current motor is started, a current rotating speed value, a preset initial rotating speed adjusting voltage value and an initial starting rotating speed value corresponding to the initial rotating speed adjusting voltage value of the brushless direct current motor are detected in real time, and when the current rotating speed value is not matched with the initial starting rotating speed value, the initial rotating speed adjusting voltage value is compensated to enable the initial starting rotating speed value to be matched with the current rotating speed value, then the compensated initial rotating speed adjusting voltage value is used for executing the starting, the braking phenomenon of the brushless direct current motor is avoided, the peak voltage generated by the power supply end VDC is effectively restrained, and master control abnormity and device damage are avoided. Meanwhile, the peak voltage can be suppressed without adding extra hardware, so that the hardware cost can be reduced.

Description

technical field [0001] The present application relates to the field of motor control, in particular to a starting method, device, storage medium and electronic equipment for a brushless DC motor. Background technique [0002] With the upgrading of energy efficiency standards, the demand for brushless DC motors in household appliances such as air conditioners, purifiers, heaters, and fans is gradually increasing. The integrated intelligent power module detects the rotor position through the Hall sensor to commutate. It is widely used due to its advantages of high integration, small size, complete functions, and low cost. However, in the actual application process of the integrated intelligent power module, the existing motherboard control method is adopted. When the load of the brushless DC motor (such as: fan blades, etc.) is running at high speed, it suddenly stops, and the load is still rotating at high speed due to inertia. At this time, if When the motor is turned on ag...
