PURPOSE:To dissipate heat from a control section effectively to a stator core by holding a radiator plate by a flange for a bobbin and the stator core. CONSTITUTION:With a stator core 1, a plurality of rectangular iron plates are laminated, and a yoke for winding a single stator winding 2 and an opening 5, into which a rotor is inserted, are formed oppositely. The stator winding 2 is wound on a bobbin 30. A radiator plate 41 is held among the stator core 1 and flanges 42, 43 for the bobbin 30 by the elasticity of the flanges 42, 43. Heat from the radiator plate 41 is transmitted efficiently over the stator core 1. |
