摘要（英）：

The invention provides a motor driving circuit, a motor assembly and application equipment. The motor driving circuit comprises a bidirectional alternating current switch, a rectifying circuit, a first voltage reduction circuit, a switch control circuit, and a magnetic sensor, wherein the bidirectional alternating current switch and a motor are connected in series between the two ends of an external alternating current power supply; the bidirectional alternating current switch is connected between a first node and a second node; the rectifying circuit has a first input end and a second input end; the first voltage reduction circuit is connected between the first input end of the rectifying circuit and the first node; the switch control circuit is connected between the control end of the bidirectional alternating current switch and the output end of the rectifying circuit; the output end of the magnetic sensor is connected with the control end of the switch control circuit; and the magnetic sensor is used for detecting the magnetic field of a rotor of the motor and outputting a corresponding magnetic sensing signal. Therefore, it is ensured that the motor which applies the motor driving circuit is started and rotated in a fixed direction in power-on each time.
