Title:
ROTOR FOR ROTARY ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/104418
Kind Code:
A1
Abstract:
In the present invention, provided are center bridges (4a, 4b) that connect an inner-circumferential-side iron core part (2) and an outer-circumferential-side iron core part (3) so as to divide, into a plurality of parts in a peripheral direction, magnet insertion holes (5a-5c) into which magnets (6a-6c) that constitute one pole are inserted. The center bridges (4a, 4b) are formed so as to be parallel to and symmetrical about a pole axis (7) and so that the shapes of edge portions thereof that are adjacent to the magnet insertion holes (5a-5c) at connection portions (42, 43) which are respectively continuous with the inner-circumferential-side iron core part (2) and the outer-circumferential-side iron core part (3) are formed in an elliptical arc having a longitudinal axis in the direction parallel to the pole axis (7) or in a curved shape (50) obtained by preparing a plurality of circular arcs having radii of curvature that sequentially decrease toward the outer circumference of a rotor iron core (1) and smoothly connecting the plurality of circular arcs.
