Title:
MAGNETIC GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/145629
Kind Code:
A1
Abstract:
A magnetic gear device (100) comprising an inner rotor (1), a pole piece module (2) in which a plurality of pole pieces (21) formed from a magnetic substance and a plurality of non-magnetic substance portions (22) are alternately arranged in the circumferential direction, and an outer rotor (3) having a plurality of outer rotor magnets (32) arranged in the circumferential direction, wherein the inner rotor (1), the pole piece module (2), and the outer rotor (3) are provided so as to be spaced apart from each other in the radial direction of a shaft. The magnetic gear device (100) is configured such that a radially inner side width Rp_in of the pole piece (21) is larger than a radially outer side width Rp_out of the pole piece (21) and a maximum width Lm_out of the outer rotor magnet (32) in the circumferential direction is larger than the radially outer side width Rp_out of the pole piece (21) and smaller than an outer diameter width Ra_out of the non-magnetic substance portion (22).
