The present invention relates to a single phase induction motor, and more particularly, to a single phase induction motor, wherein a variable resistance element which can change a winding number of a main winding or an auxiliary winding capable of producing a magnetic field at the time of starting is connected in parallel to some portion of the main winding or the auxiliary winding. A single phase induction motor including a stator composed of a core, a main winding and an auxiliary winding, and a rotor rotated by a mutual electromagnetic force by the stator comprises a resistance variable element connected in parallel to some portion of the main winding. In addition, a single phase induction motor including a stator composed of a core, a main winding and an auxiliary winding, and a rotor rotated by a mutual electromagnetic force by the stator comprises a capacitor connected in series to the auxiliary winding, and a resistance variable element connected in parallel to some portion of the auxiliary winding and the capacitor.
