Title:
回転共振型モータ
Document Type and Number:
Japanese Patent JP4041120
Kind Code:
B2
Abstract:
A swing motor having an opening formed asymmetrically inside a stator 10. The swing motor is formed with an asymmetrical opening, in particular in a semicircular shape inside the stator 10. The opening is provided with a plurality of salient poles 11 and 12 wound with coils 11a and 12a. Electric current alternately flows through the coils 11a and 12a so that a rotor 20, installed in the stator 10 in a state of being spaced apart from the stator 10, can reciprocally move. Since the height of the stator 10 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.
