Abstract
A swing motor having an opening formed asymmetrically inside a stator. The swing motor is formed with an asymmetrical opening, in particular in a semicircular shape inside the stator. The opening is provided with a plurality of salient poles wound with coils. Electric current alternately flows through the coils so that a rotor, installed in the stator in a state of being spaced apart from the stator, can reciprocally move. Since the height of the stator is reduced by forming the opening asymmetrically in comparison with the case of forming the opening symmetrically, it is advantageous for minimizing the size of the product in which the swing motor is installed.
