The invention belongs to the technical field of sleep aids, and in particular relates to a driving circuit of a shaded pole motor sleep aid, which includes a constant voltage adaptation unit, a WiFi circuit, an LED control circuit, and a fan motor control circuit respectively connected to a single-chip electromechanical device. In addition to the inherent transformer, the distribution unit is also equipped with a switching power supply chip for voltage feedback control, which provides a more stable working power supply. The structure design of the WiFi circuit, LED control circuit and fan motor control circuit is simpler, while reducing the complexity of the control circuit. , also makes the MCU control the fan speed more reliable, making the generated white noise more stable and comfortable, and the MCU is connected to the two-way fan motor control circuit, which is used as the two gears of the fan motor, making the white noise sleep aid function more humane.
