摘要： It is an object of the invention to secure an insulation distance between a stator and a rotor without reducing a region of a slot of a stator core in which a winding is installed. The representative electric motor includes a cylindrical stator core 131 fixed to a motor housing, a rotor 120 rotatably housed within a housing part 132 in a bore of the stator core 131, pole pieces 133, 134 extending from an inner wall 131a of the stator core 131, rotor opposed surfaces 133a, 134a of the pole pieces 133, 134 which are opposed to the rotor 120, inner-wall opposed surfaces 133b, 134b of the pole pieces 133, 134 which are formed on a side opposite to the rotor opposed surfaces 133a, 134a and opposed to the inner wall 131a of the stator core 131, a slot 135 which is defined between the inner wall 131a of the stator core 131 and the inner-wall opposed surfaces 133b, 134b of the pole pieces 133, 134 and in which the winding 137 is installed, a first insulating sheet 141 which is disposed in the slot 135 and insulates the winding 137 from the stator core 131, a space 138 which is defined between the slot 135 with the winding 137 installed therein and the housing part 132 with the rotor 120 housed therein, and a second insulating sheet 142 which is disposed in the space 138 and insulates the winding 137 from the rotor 120.
