20110277314 | STATOR COIL PRODUCTION METHOD AND STATOR COIL PRODUCTION MACHINE - A stator coil producing method and a stator coil production machine. The stator coil is used in an electric rotating machine. The stator coil production machine includes a rotary retainer which rotates to move shaping press pairs along a looped path. The rotary retainer has retaining holes through which the shaping press pairs are retained. The retaining holes are shaped to permit the shaping press pairs to move along the looped path, thereby pressing or shaping portions of a conductor wire into in-slot portions to be disposed in slots of a stator core and coil-end portions each of which is to extend between adjacent two of the in-slot portions outside the slots. The method comprises an in-slot portion shaping step of shaping portions of the insulator-coated conductor wire into the in-slot portions and a coil-end portion shaping step of shaping portions of the insulator-coated conductor wire into the coil-end portions. | 11-17-2011 |
20110277315 | STATOR COIL PRODUCTION METHOD AND STATOR COIL PRODUCTION MACHINE - A stator coil producing method and a stator coil production machine. The stator coil is used in an electric rotating machine. The stator coil production machine includes a rotary retainer which retains and moves shaping press pairs along a looped path to press or shape portions of a conductor wire into in-slot portions to be disposed in slots of a stator core and coil-end portions which extend outside the slots. The method comprises a coil-end portion shaping step of bringing press members of each of the shaping press pairs close to each other in sequence to shape the coil-end portions and an in-slot portion shaping step of advancing the shaping press pairs on the looped path in contact with the cam mechanism and also moving selected ones of the shaping press pairs in sequence in a direction perpendicular to the path to shape the in-slot portions. | 11-17-2011 |
20110278980 | STATOR COIL PRODUCTION METHOD AND ELECTRIC MOTOR EQUIPPED WITH STATOR COIL PRODUCED BY THE SAME - A stator coil production method using a plurality of shaping press pairs. A stator coil is made up of in-slot portions to be disposed in slots of a stator core and coil-end portions each of which extends every adjacent two of the in-slot portions. Each of the shaping press pairs has a die and a punch disposed on both sides of a conductor wire travel path. The method includes a first step of moving the die and the punch close to each other to shape a portion of a conductor wire into one of the coil-end portions, and a second step of bringing adjacent two of the shaping press pairs close to each other and simultaneously moving one of the adjacent two of the shaping press pairs in a direction perpendicular to the conductor wire to shape a portion of the conductor wire into one of the in-slot portion. | 11-17-2011 |
