PERMANENT MAGNET DYNAMO-ELECTRIC MACHINE AND MOTOR-DRIVEN VEHICLE EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a permanent magnet dynamo-electric machine which is suitable for a high speed operation, highly efficient and small in size and weight and, further, provide a motor-driven vehicle which can run a long distance with one charge by employing such a permanent magnet dynamo-electric machine. SOLUTION: A dynamo-electric machine 10 is composed of a stator 20 which has a stator core 22 on which stator windings 24 are wound and a rotor 30 which is held inside the stator 20 so as to be able to rotate and has a rotor core 32 and a plurality of permanent magnets 36 which are so arranged in the rotor core 32 as to face the stator core 22. The stator windings 24 are concentratedly wound on the poles 22B of the stator 20.
