Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/011782
Kind Code:
A1
Abstract:
A rotary electric machinery is realized which is able to effectively cool a permanent magnet while suitably securing intensity of a rotor core. A rotor core (3) includes a plurality of magnetic resistance holes (22a) corresponding to each of a plurality of magnetic poles, and a radial communication path (30) that is extended in a radial direction (R) so as to cause each of the plurality of magnetic resistance holes (22a) to communicate with shaft insertion holes (20), specific magnetic body plates (51, 52), which are parts among the plurality of magnetic body plates (50) forming the rotor core (3), include through holes (40a) that are formed between the shaft insertion hole (20) and the magnetic resistance holes (22a) in the radial direction (R) and are penetrated in an axial direction (L). The radial communication path (30) is constituted by a communication through hole group (31) that is formed by causing the plurality of through holes (40a), which is divided into at least two sheets of specific magnetic body plates (51, 52), has positions different from each other in the radial direction (R), and is formed so that parts overlap each other when viewed from the axial direction, to sequentially communicate from the shaft insertion hole (20) to the magnetic resistance holes (22a) in the radial direction.
