Patent ID: 8108983

Claim:
A method of manufacturing a rotary motor, said method comprising: a step of winding a conductor line on an armature core by sequentially repeating: a first step of pulling out one of magnetic tooth members of said armature core in a radial direction, said armature core being splittable into said individual magnetic tooth members, and forming a concentrated-winding type coil on said one magnetic tooth member; a second step of pushing back said one magnetic tooth member into position and connecting an end portion of said concentrated-winding type coil to a connecting terminal of a commutator which has the same number of segments as the number of said magnetic tooth members; and a third step of winding the conductor line connected to the connecting terminal of said segment on another of said magnetic tooth members adjacent to said one magnetic tooth member to form another concentrated-winding type coil; and a step of relatively turning said armature core and said commutator by a specific angle to shape the conductor line interconnecting the end portion of said concentrated-winding type coil on each of said magnetic tooth members and the connecting terminal of said segment generally into a straight line and fixing a rotary shaft to said armature core and said commutator.
