Title:
OUTER DISC TYPE MOTOR WITH FENCE TYPE STATOR
Document Type and Number:
WIPO Patent Application WO/2020/147117
Kind Code:
A1
Abstract:
Disclosed is an outer disc type motor with a fence type stator, the motor comprising a pivot (12); a plurality of disc type outer rotors (14, 81) arranged in parallel, each disc type outer rotor comprising a disc body (141), and an even number of permanent magnets (93, 143, 143', 143''), with the center of the disc body (141) being fixedly arranged on the pivot (12) vertically, adjacent permanent magnets (93, 143, 143', 143'') being evenly distributed in a homopolar opposite manner, and different magnetic poles of the permanent magnets (93, 143, 143', 143'') of the disc type outer rotors (14, 81) being opposite to one another; a fence type stator (16, 16') comprising a plurality of elongated iron cores (161, 161', 161''), with the iron cores being arranged in parallel and uniformly distributed at a circular tube with the pivot (12) as the center in the axial direction, two poles of the iron core respectively corresponding to the permanent magnets (93, 143, 143', 143''), and the number of the iron cores being greater than one times and less than two times the number of the permanent magnets (93, 143, 143', 143''); and an enabling controller (20) providing alternating current clock pulse type driving signals, so that every two adjacent clock pulse type driving signals have a uniform phase difference, and the total phase difference of the fence type stator (16, 16') is a non-zero integer multiple of 360 degrees.
