A Rotating Electrical Machine
Abstract: A rotating electrical machine is provided having a stator (102), a rotor (103) to be rotated with respect to the stator (102) and a rotation angle detector. The rotation angle detector has a detecting stator (2) with a detecting stator core (21), and a plurality of excitation windings (22), a first output winding (23), and a second output winding (24) that are each provided on the detecting stator core (21). A detecting rotor (3) is provided with a plurality of salient poles (31) arrayed in a circumferential direction, and being rotatable with respect to the detecting stator (2), while each of the plurality of salient poles (31) is opposed to the detecting stator (2) in a radial direction. The detecting rotor (3) is rotated integrally with the rotor (103). The first output winding (23) and the second output winding (24) comprise output windings with mutually different phases. In essence, a spatial distribution of a number of turns in each of the first output winding (23) and the second output winding (24) is obtained by a function represented by a sum of a function represented by a sine wave of a spatial order |M±N|, and a function represented by a sine wave of a spatial order |M-|M±N|| having an amplitude equal to an amplitude of the sine wave of the spatial order |M±N| and an error spatial order δ represented by |M-|M±N|| and an error spatial order ε represented by |δ-M| are values other than 1 and 2.
