Abstract
A hollow low-current single-phase induction motor capable of starting under its own power may have a stator and a rotor. The stator may comprise a case and a winding. The case may have a base, an annular outer circumferential wall, an annular inner circumferential wall, a plurality of first extensions formed at the outer circumferential wall, and a plurality of second extensions formed at the inner circumferential wall so as to respectively face the first extensions. The rotor may have a flange, a plurality of coil supports formed along the outside circumference of the flange, and a plurality of annular rotor coils which are attached to the respective coil supports. The coil supports may be inserted between the first extensions and the second extensions such that at least one thereamong is misaligned in the circumferential direction relative to the first extensions and the second extensions.
