Title:
PERMANENT MAGNET ROTATING APPARATUS FOR MINIMIZING COGGING TORQUE
Document Type and Number:
WIPO Patent Application WO/2016/006937
Kind Code:
A1
Abstract:
The present invention relates to a permanent magnet rotating apparatus for minimizing cogging torque and, more particularly, to a permanent magnet rotating apparatus which minimizes cogging torque simply through a combination of a pole and a slot, and an appropriate arrangement between permanent magnets, without using multiple traditional methods for reducing cogging torque such as skew and tooth processing, which drive up costs.
