ROTATING ELECTRICAL MACHINE

摘要

[Problem] To make it possible to perform driving in an optimum operation state by means of using a control motor in a mechanism that changes a field magnetic flux. [Solution] A variable field magnet rotating electrical machine (1) that changes a field magnetic flux has: an outer circumferential-side rotor (20) that is provided with a plurality of first permanent magnets (21), which are disposed in the circumferential direction; an inner circumferential-side rotor (30), which is coaxially disposed on the inner side of the outer circumferential-side rotor (20), and which is provided with a second permanent magnet (31); and a rotating mechanism (50), which is configured so as to relatively rotate the outer circumferential-side rotor (20) and the inner circumferential-side rotor (30) by means of a control motor (53).
