Title:
ELECTRIC GENERATOR FOR REDUCING COGGING TORQUE
Document Type and Number:
WIPO Patent Application WO/2019/083067
Kind Code:
A1
Abstract:
The present invention relates to an electric generator for reducing cogging torque and, more specifically, to an electric generator for reducing cogging torque, the electric generator reducing cogging torque and leakage flux generated during driving of the electric generator, thereby enabling generation efficiency of the electric generator to increase. The electric generator for reducing cogging torque, according to the present invention, repeatedly changes, along a circumferential direction, an interval between an end portion of a permanent magnet provided in a rotor and teeth formed in a stator, thereby enabling cogging torque to be remarkably reduced in comparison with a conventional electric generator in which an interval between a permanent magnet and teeth is uniformly fixed.
