Document Type and Number:
WIPO Patent Application WO/2021/176977
Kind Code:
A1
Abstract:
An eddy current-type speed reducer (100) includes a rotor (10) and a stator (20). The rotor (10) includes a hub (12), a rotor body (11), and a spoke (13). The spoke (13) has neutral axes (N1, N2). The neutral axis (N1) is a neutral axis when the spoke (13) is bent in the circumferential direction of the rotor body (11). The neutral axis (N1) is located ahead of a center line (C1) of the spoke (13) in the circumferential direction in the rotation direction (R) of the rotor (10). The neutral axis (N2) is a neutral axis when the spoke (13) is bent in the axial direction of the rotor body (11). The neutral axis (N2) is located closer to the rotor body (11) than a center line (C2) of the spoke (13) in the axial direction.
