Patent ID: 7619334

Claim:
A toroidal motor comprising: a stator including a stator core having a yoke and a plurality of teeth extending from an inside circumference of the yoke, the stator core having a slot therein, a stator winding wound on the yoke of the stator core toward an outside circumference of the yoke from the slot in the stator core, a grounding terminal mounted on the stator winding, the grounding terminal having a first end protruding toward the outside circumference of the yoke, and a conductive pin electrically connecting the grounding terminal to the stator core; a rotor provided with a shaft; and a bracket for receiving a bearing which rotatably supports the shaft, wherein at least one hole is provided in the stator core, the hole having a predetermined diameter and being provided in a tooth of the plurality of teeth of the stator core, wherein a first end of the conductive pin is press fitted in the hole and a second end of the conductive pin is connected with a second end of the grounding terminal, wherein the grounding terminal extends along the yoke from the second end connected to the conductive pin so that a side of the grounding terminal faces the yoke, and wherein the stator is formed by integrally molding the stator core, the stator winding, the grounding terminal, and the conductive pin with an insulating resin.
