A control circuit of a single-phase AC motor for a dryer includes a start control unit, a first drive circuit, a first triac, a second drive circuit, and a second triac. The first triac is connected to an AC input of a mains supply via a start winding and a start capacitor of the motor connected in series. The start control unit is connected to the control terminal of the first triac via the first drive circuit. The second triac is connected to the AC input of the mains supply via an electric heating wire. The start control unit is connected to the control terminal of the second triac via the second drive circuit. The first drive circuit is formed to interlock with the second drive circuit. |
