Abstract

See full text

In a rotor in which magnet slots arranged in a V shape so as to open toward the outer circumferential side and having permanent magnets inserted therein are formed in a two-layer structure in a radial direction, the magnet slots in each layer are composed of a pair of slots formed between a center bridge located at the center and respective ones of two radially-outer bridges located between the outer surface of the rotor and the respective slots. Of magnetic fluxes generated from the permanent magnets, magnetic fluxes excluding magnetic fluxes for magnetically saturating the bridges are defined as effective magnetic fluxes. The rotor is configured such that the effective magnetic flux generated from the permanent magnet on the radially outer side is not greater than half the effective magnetic flux generated from the permanent magnet on the radially inner side.
