Abstract
A rotating electric machine for vehicular use includes: a stator that includes a stator core and a stator winding wound at the stator core; and a rotor that is rotatably disposed relative to the stator and includes a rotor core formed by laminating a plurality of electromagnetic steel sheets with a plurality of magnet insertion holes formed therein and includes a plurality of permanent magnets each held in each of the plurality of magnet insertion holes to form a magnetic pole. Each of the plurality of permanent magnets extends along a rotor axis and is formed in a shape assuming at least two different lengths along a circumference of the rotor.
