Title:
MAGNETIC GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/043387
Kind Code:
A1
Abstract:
Provided is a magnetic gear device capable of suppressing the loss of eddy current three-dimensionally flowing in a magnetic flux, and of providing high torque transmission efficiency. The magnetic gear device is provided with: first and second rotors (1, 2) each having a plurality of permanent magnets (1a, 2a); and a stator (3) that is disposed magnetically between the first rotor (1) and the second rotor (2) and that has a plurality of pole pieces (3a) capable of modulating a magnetic flux. The first rotor (1) is opposed to the stator (3) via a radial gap (RG) perpendicular to the rotation axis (O1) of the first rotor (1). The second rotor (2) is opposed to the stator (3) via an axial gap (AG) parallel to the rotation axis (O2) of the second rotor (2). The pole pieces 3a are formed of powder magnetic cores.
