PROBLEM TO BE SOLVED: To provide a reliable mold motor capable of achieving long life and long drive by efficiently radiating heat generated in drive. SOLUTION: The mold motor 20 is a motor for motor-driven vehicles 1 where a stator core 24 is covered with an insulating mold resin 21, and includes a motor case 50 including and holding the mold resin 21, where the motor case 50 includes openings 54-57 for locally exposing the mold resin 21. Thus, a place, where the mold resin 21 is directly exposed to the air, is provided, and the openings 54-57 directly radiate heat of the mold motor 20. COPYRIGHT: (C)2011,JPO&INPIT |
