Title:
METHOD FOR MANUFACTURING STATOR AND INNER ROTOR OF GENERATOR
Document Type and Number:
WIPO Patent Application WO/2020/027557
Kind Code:
A1
Abstract:
The present invention relates to a stator and an inner rotor of a generator, which can improve rotational force and significantly reduce vibration and noise by minimizing cogging torque caused by a correspondence in an airgap flux density by a slot of the stator, and distortion of a current. According to the present invention, a tip is formed at an outer end of a coil winding piece of a stator core of the generator, and the inner rotor is formed having a ring structure and a ring structure with a cross-shaped support, and rotates at the same speed as an outer rotor.
