Abstract
The invention provides a electric motor which is capable of easily holding and fixing a winding terminal connector for holding and connecting each winding terminal of a stator winding and is superior in workability and resistance to vibration. The electric motor comprises: a stator core ; a rotor held by a rotary shaft with a predetermined void between the stator core and the rotor ; a bobbin-shaped insulator mounted on the stator core , provided with a flange portion on at least one of outer diameter side and inner diameter side, and wound with a stator winding ; a terminal holder fixed to the flange portion of the bobbin-shaped insulator and provided with a cylinder portion arranged so as to surround the rotary shaft ; and annular conductors and insulating layers arranged on outer diameter side of the cylinder portion of the terminal holder and laminated alternately in axial direction; in which the annular electric conductors are provided with a connecting portion for connecting terminal lead wires of the stator winding corresponding to lead positions of the terminal lead wires
