Specifically, when the movable contact is switched to be connected with the first stationary contact, the relay K1 is in an off state; when the movable contact is switched to be connected with the second stationary contact, the relay K1 is in a closed state, and at the moment, the diode D1, the adjustable resistor RP1 and the relay K1 are connected in series and then connected in parallel to two ends of the motor 2.
