Publication number: 20110277314Abstract: 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.Type: ApplicationFiled: May 12, 2011Publication date: November 17, 2011Applicant: DENSO CORPORATIONInventors: Daisuke OKUSHITA, Yusuke Hara, Takao Takeuchi, Kiyokazu Futami, Satoshi Nakamura, Fumihiro Nakano

Patent number: 8020282Abstract: An apparatus for producing a coil winding for stators is described, in which each coil turn rests, with one fillet (14) each, in two stator slots, and the two fillets (14) are joined by a head portion (16). A plurality of coil turns are made simultaneously by winding up n parallel wires (10) with intermediate spacing onto a rotatable former (20). To obtain small winding heads, alternatingly in a work step A, one fillet (14) and the wire length of one head portion (16) are made from each of the n parallel wires (10) on the former (20). Then in a work step B, the resultant fillets (14) together with the adjoining first end of the respective associated head portions (16), and the wire guide together with the second end of these head portions (16), are displaced relative to one another along the former (20) by n times the intermediate spacing of the wires (10).Type: GrantFiled: March 31, 2010Date of Patent: September 20, 2011Assignee: Elmotec Statomat Vertriebs GmbHInventors: Sadik Sadiku, Keith A.

Patent number: 7975370Abstract: Stator designs have wide-mouth slots between adjacent poles. Wire coils with high slot fill conductivity are formed around the poles. In some designs, the wire coils are wave wound around the poles. Thick bar conductors can be used for making the wire coils. The wire coils may be inserted using nozzle dispensers or transferred from a pre-form mandrel. In other designs, the wire coils are pre-formed on transferable pockets that are then mounted on the poles. Optional pole extensions or shoes can be attached to the stator poles after the wire coils are formed around the poles.Type: GrantFiled: July 7, 2010Date of Patent: July 12, 2011Assignee: ATOP S.p.A.Inventors: Raffaele Becherucci, Massimo Pelletta, Rodolfo Pes, Gianfranco Stratico

Patent number: 7886422Abstract: A method is provided for reclaiming a suspension from a disk drive head gimbal assembly (HGA). An ultrasonic probe is applied to the HGA's read/write head slider on a side opposite that of its solder balls. Ultrasonic oscillations are transmitted through the ceramic slider to the side with the solder balls. The oscillations break the brittle intermetallic compound of the slider balls and free the slider. The ultrasonic energy also weakens the epoxy adhesive between the slider and suspension. The method can be used with heat to further weaken the solder balls and adhesive.Type: GrantFiled: August 5, 2008Date of Patent: February 15, 2011Assignee: Magnecomp CorporationInventors: Haiming Zhou, Haijun Gao, Fei He
