<P>PROBLEM TO BE SOLVED: To provide an electric motor which reduces the increase of an iron loss due to welding even when fixed to a housing by welding and thereby achieving high efficiency. <P>SOLUTION: An electric motor of this invention is composed of a stator 10 and a rotor 20, and the stator 10 has an annular yoke 14 and multiple teeth 12 disposed on an inner peripheral part of the yoke. Three phase concentrated winding coils 13 are wound around the teeth through an insulator (an insulation film, an insulator, the like: not shown in the figure). The annular yoke 14 is fixed to a housing 30 by welding, and the welding is performed on the teeth outer peripheral side yoke 11 positioned on the teeth outer peripheral side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
