Patent number: 10994348Abstract: A system for cutting to length at least two strands of long rolled products (3, 5) preferably coming from a hot rolling mill. The system includes shears comprising at least two rotatable drums (4,6), each drum having a cutter (8,8?,10,10?) arranged to cut simultaneously at least two strands of long rolled products into finished segments. The system further includes at least two movable guides (12,14), each including at least two channels, each guide arranged to receive and guide at least one strand (3,5) of long product. The guides are movable between a position wherein, in operation, the strands of long product are located in positions either outside of the trajectory of the cutters in a position wherein the strands cannot be cut or wherein the strands are located on the trajectories of the cutters and can be cut by the cutters.Type: GrantFiled: June 26, 2014Date of Patent: May 4, 2021Inventors: Roberto Albè, Roberto Bianchi, Ezio Colombo

Patent number: 10938256Abstract: In a motor stator, terminal wires of a coil are led out respectively from a feed-side and a neutral-side coil end. With three circumferentially adjacent first-, second-, and third-phase coils as one set, the leading end portion and intermediate portion of one of three terminal wires led out from the neutral side are connected to each of the remaining terminal wires. A structure wherein the first- and second-phase terminal wires are connected together in one position, and the second- and third-phase terminal wires are connected together in a different position from the one position, is adopted, thus compacting the size of one wire connection portion.Type: GrantFiled: October 15, 2018Date of Patent: March 2, 2021Assignee: Mitsubishi Electric CorporationInventors: Kota Katsuragi, Shoichiro Nishitani, Shinichiro Yoshida, Ryuji Kitamura, Fumitaka Totsuka

Patent number: 10166586Abstract: A combined iris and shear unit for a coil forming device is provided that includes an actuator and a plurality of support members coupled together in series to support formation of a coil and connected to the actuator. Each support member further comprises a retractable shear blade. The actuator adapted to cause movement of the support members between an open position with the blades of the combined iris and shear unit being retracted away from the reform tub wall, so that coil forming takes place within the reform tub without interference. A support position with the blades extends into the reform tub and providing support for the coil; or a shear position for cutting the coil before it is extracted.Type: GrantFiled: May 3, 2013Date of Patent: January 1, 2019Assignee: PRIMETALS TECHNOLOGIES USA LLCInventor: Robert John Castle

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: 7650682Abstract: In a state in which a first divisional core and a second divisional core are arranged in a state spaced from each other and adjacent to each other, a first coil and a second coil are each wound around a tooth. The first coil and the second coil are in the same phase. In a state in which a plurality of divisional cores are arranged annularly so that their teeth are oriented in a radially inward direction, the first divisional core and the second divisional core are not adjacent to each other in the circumferential direction. A plurality of connection wires are shaped to converge at an end surface of a stator core. This facilitates the winding of the coils around the divisional cores. Further, the connection wires can be shortened.Type: GrantFiled: February 7, 2007Date of Patent: January 26, 2010Assignee: Asmo Co., LtdInventors: Kazushi Sugishima, Akihiro Suzuki

Patent number: 7003867Abstract: A core includes a ring body and a plurality of teeth. The teeth extend radially outward form the outer circumference of the ring body. The core is formed by assembling a first core member and a second core member. Each core member has part of the teeth the number of which is half the total number of the teeth. Each tooth includes a tooth body about which the coil is wound, and a magnetism converging portion provided at the distal end of the tooth body. The tooth height of each tooth body gradually increases from a distal section to a proximal section of the tooth body. The tooth width gradually decreases from the distal section to the proximal section. The wire is wound about each of the teeth of the first and second core members. Then, the first and second core members are assembled to form the core. Accordingly, a rotor core having a high coil accommodation efficiency and a high coil space factor is obtained.Type: GrantFiled: October 15, 2003Date of Patent: February 28, 2006Assignee: Asmo Co., Ltd.Inventors: Toshio Yamamoto, Atsuo Okamoto, Takerou Totsuka, Akiyoshi Katou

Patent number: 6532645Abstract: Methods and apparatus are provided for wire winding and fabrication for dynamo-electric machine components such as ferromagnetic armature or stator cores for motors or the like. Wire may be wound onto individual portions of dynamo-electric machine components, which may then be assembled to form complete components. Wire may be wound by steering a rotating flyer or the like in a trajectory that closely follows the surface of the core onto which the wire is being wound. Wire may also be wound by rotating the portions during winding. The same holding members that are used to hold the portions during winding may be used to hold the portions during assembly of the portions into machine components.Type: GrantFiled: October 26, 2000Date of Patent: March 18, 2003Assignee: Axis USA, Inc.Inventors: Raffaele Becherucci, Gianfranco Stratico
