PURPOSE:To compactly form a start switch by supporting rotatably in the prescribed range a stator of a motor to a stationary shaft, and operating the switch of a starting capacitor on the basis of the reverse rotation of the stator. CONSTITUTION:A stator 12 is rotated at the initial time of starting, and the stator 12 and a stator shaft 11 are rotated reversely in the allowed amount. Thus, a driven cam 19 is slid at a drive cam 18 as a base point in an inner end direction, a start switch 38 is closed by the movement of the cam, and a starting capacitor 36 is energized. When a motor 10 is started and its rotation is stabilized, the stator 12 is rotated and reset to the position where is balanced with the drive force of an outer rotor 13, and the switch 38 is opened to open the capacitor circuit 36. |
