Document Type and Number:
WIPO Patent Application WO/2019/024529
Kind Code:
A1
Abstract:
Disclosed is a nested winding used for a non-cogging electric motor, wherein the winding is formed of n nested coils with different inner and outer diameters, and coils with the same phase are connected in parallel or in series, wherein the number of nested coils n is greater than or equal to 2. Compared with the prior art, the winding can effectively reduce potential difference between coils connected in parallel, thereby reducing loss in the winding, and having advantages such as increasing the high speed operating performance of an electric motor.
