Title:

MAGNETIC GEARED ROTATING ELECTRICAL MACHINE AND MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/145232

Kind Code:

A1

Abstract:

This magnetic geared rotating electrical machine includes: a stator; a low-speed rotor that includes a plurality of pole pieces arranged juxtaposed in a circumferential direction, and that is provided on an inner side of the stator; and a high-speed rotor that includes a plurality of second magnets that are magnets facing the pole pieces, and that is provided on an inner side of the low-speed rotor. The magnetic geared rotating electrical machine further includes: a first piezoelectric element that is provided on the pole pieces, and that converts vibration and electrical signals; and a control unit that is connected to the first piezoelectric element, and that suppresses the vibration of the pole pieces on the basis of an output voltage of the first piezoelectric element.
