DYNAMO-ELECTRIC MACHINE FOR USE IN VEHICLES

A rotating electric machine for vehicular use having n types of magnet pieces includes: a stator (230) that includes a stator core (232) and a stator winding (238) wound at the stator core (232); and a rotor (250) that is rotatably disposed relative to the stator (230) and includes a rotor core (252) formed by laminating a plurality of electromagnetic steel sheets with a plurality of magnet insertion holes (272) formed therein and includes a plurality of permanent magnets (254, 255) each held in each of the plurality of magnet insertion holes (272) to form a magnetic pole. Each of the plurality of permanent magnets (254, 255) extends along a rotor axis and is formed in a shape assuming at least two different lengths along a circumference of the rotor.
