MAGNETIC TRANSMISSION

WIPO Patent Application WO/2017/104359

A1

A magnetic transmission is provided with an inner rotor (1), an outer rotor (2), and a magnetic field-modulating stator (3) disposed coaxially between the inner rotor (1) and the outer rotor (2). The inner rotor (1) is provided with a first magnet row (11) and a second magnet row (12) that are disposed in parallel in the direction of the central axis (A) and disposed at different pitches along the circumferential direction. The outer rotor (2) is provided with a magnet row that is disposed along the circumferential direction. The magnetic field-modulating stator (3) is provided with a first magnetic body row (31) and a second magnetic body row (32) that oppose the first magnet row (11) and the second magnet row (12), respectively. Moreover, by moving the inner rotor (1) and the magnetic field-modulating stator (3) in the direction of the central axis (A) while maintaining the opposing relationship between the first magnetic body row (31) and the second magnetic body row (32) and the first magnet row (11) and the second magnet row (12), the position of opposition between the outer rotor (2) and the first magnet row (11) and second magnet row (12) is varied continuously.
