Title:
Permanent magnet coupling
Document Type and Number:
Japanese Patent JP6007107
Kind Code:
B2
Abstract:
The invention relates to a permanent magnet coupling for synchronously transmitting rotary motions, having a first rotor (1a) and a second rotor (1b), each covered by permanent magnets (2a, 2b) and forming an inner rotor and an outer rotor, wherein permanent magnets (2a, 2b) of the first rotor (1a) and the second rotor (1b) associated with each other extend over the same angle range in the circumferential direction. According to the invention, unfilled intermediate spaces (5) are formed on the first rotor (1a), starting from complete coverage by permanent magnets (2a) in the circumferential direction, by leaving out a portion of the permanent magnets (2a), wherein the first rotor (1a) and the second rotor (1b) comprise a different number of permanent magnets (2a, 2b).
