Abstract
Official abstract text for this publication.
A magnetic wave gear device ( 1 A, 1 B, 1 F) includes: a first member ( 10 ), a second member ( 20 ), and a third member ( 30 ) which are rotatable relative to one another around a rotation axis (R). The second member ( 20 ) is disposed between the first member ( 10 ) and the third member ( 30 ), and includes magnetic material pieces ( 21 ). The first member ( 10 ) includes first permanent magnets ( 12 A, 12 B). The third member ( 30 ) includes: a plurality of pole teeth ( 32 ), a pole tooth ( 32 ) being wound with a coil ( 33 ); and second permanent magnets ( 34 B), each second permanent magnet ( 34 B) being disposed between pole teeth ( 32 ) next to each other, and the magnetic poles of sides of the second permnanent magnets ( 34 B) facing the second member ( 20 ) being the same pole.
First claim
Opening claim text (preview).
1 . A magnetic wave gear device comprising: a first member, a second member, and a third member which are rotatable relative to one another around a rotation axis, wherein the second member is disposed between the first and third members, and includes a plurality of magnetic material pieces disposed around the rotation axis, the first member includes a plurality of first permanent magnets facing the second member and disposed around the rotation axis, the third member includes: a plurality of pole teeth facing the second member and disposed around the rotation axis, a pole tooth being wound with a coil, and a plurality of second permanent magnets, each second permanent magnet being disposed between pole teeth next to each other, and magnetic poles of sides of the second permanent magnets facing the second member being the same pole. 2 . The magnetic wave gear device according to claim 1 , wherein the plurality of first permanent magnets are disposed such that magnetic poles of first permanent magnets next to each other are opposite to each other in a radial direction. 3 . The magnetic wave gear device according to claim 1 , wherein the plurality of first permanent magnets are disposed such that magnetic poles of sides of the first permanent magnets facing the second member are the same pole. 4 . The magnetic wave gear device according to claim 3 , wherein a second magnetic material piece is disposed between first permanent magnets next to each other. 5 . The magnetic wave gear device according to claim 1 , wherein the second permanent magnet is disposed between the coil and the second member in a radial direction. 6 . The magnetic wave gear device according to claim 1 , wherein the third member further includes a pole tooth intermediate portion disposed between coils wound on pole teeth next to each other, and the second permanent magnet is disposed between the pole tooth intermediate portion and the second member in a radial direction. 7 . The magnetic wave gear device according to claim 1 , wherein the second permanent magnet is provided so as to contact the pole tooth. 8 . The magnetic wave gear device according to claim 1 , wherein a gap is formed between the second permanent magnet and the pole tooth.
