Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/151236
Kind Code:
A1
Abstract:
[Problem] To provide a variable field rotating electric machine in which high efficiency can be obtained. [Solution] A variable field rotating electric machine (1) that changes a field magnetic flux has: a shaft (34); a fixed rotor (50) equipped with a plurality of first magnetic pole portions (53) having alternately different polarities in a circumferential direction and fixed to the shaft (34); and a movable rotor (60) equipped with a plurality of second magnetic pole portions (63) having alternately different polarities in a circumferential direction, lying axially adjacent to the fixed rotor (50), and configured so as to rotate relative to the shaft (34). The ratio between the sum of axial dimensions of the fixed rotor (50) and the sum of axial dimensions of the movable rotor (60) is set so that the ratio of an inductive voltage generated when the first and second magnetic pole portions (53, 63) of different polarities are axially aligned to an inductive voltage generated when the first and second magnetic pole portions (53, 63) of the same polarity are axially aligned becomes a desired value.
