Problems solved by technology

[0004] In the prior art, in order to reduce the standby power consumption of the DC explosion-proof motor control part in household appliances, the best way is to prevent this part from power loss during standby. The existing DC explosion-proof motor power supply part and the whole machine controller The power supply part is separated, that is, multiple power supplies are controlled in the same whole machine, that is, it is necessary to provide power to the control chip, to provide power to the drive module, and to provide power to the brushless explosion-proof motor, and the voltage value of the source They are all different, but due to the small size of the products using brushless explosion-proof motors, the space for installing the controller is greatly limited, resulting in increased product costs;
[0005] For the control of brushless explosion-proof motors in the prior art, it is impossible to monitor the speed, and when the control signal of the brushless explosion-proof motor controls the brushless explosion-proof motor, because there is no reference, the control signal voltage drop will be low. Causes distortion and cannot form precise control of brushless explosion-proof motors
