Document Type and Number:
WIPO Patent Application WO/2021/149420
Kind Code:
A1
Abstract:
Provided is an electric motor (100) with two degrees of freedom that is able to achieve low loss and high output. The present invention has a first stator (10), a second stator (20), a first rotor (40), and a drive shaft (30). N-pole magnets (41) of N-pole regions of the first rotor (40) are arranged in a line along a right-tilting direction with intervals therebetween. S-pole magnets (42) of S-pole regions of the first rotor (40) are arranged in a line along the right-tilting direction with intervals therebetween, and are positioned so as not to overlap with the N-pole magnets (41) of the N-pole regions in a θ direction. N-pole magnets (31) of N-pole regions of the drive shaft (30) are positioned along the right-tilting direction and a Z-axis direction. S-pole magnets (32) of S-pole regions of the drive shaft (30) are positioned along the right-tilting direction and the Z-axis direction.
