Patent number: 9240709Abstract: A manufacturing method for an electric motor rotor includes: a stacking process in which a plurality of iron core pieces are stacked to form a laminated iron core; a magnet insertion process in which a permanent magnet is inserted into a magnet insertion hole provided in the laminated iron core; a resin filling process in which the laminated iron core is heated to fill the magnet insertion hole with a molten resin for magnet fixation; and a rotary shaft assembly process in which a rotary shaft is warm-fitted into a rotary shaft insertion hole of the laminated iron core utilizing residual heat from the heating of the laminated iron core 10 in the resin filling process.Type: GrantFiled: February 3, 2012Date of Patent: January 19, 2016Assignee: AISIN AW CO., LTD.Inventors: Susumu Kato, Shigeru Maeda, Takeshi Yokoyama, Takuya Ooura, Motoki Koori

Patent number: 8951030Abstract: A resin filling device for a laminated iron core, the resin filling device being used when a magnet insertion hole provided in the laminated iron core of a rotor for an electric motor is filled with a molten resin for fixing a magnet. The resin filing device configured with a resin feeding mold, an opposing mold, and a pressing mechanism that applies a compression force with the laminated iron core sandwiched between the resin feeding mold and the opposing mold. The resin feeding mold includes one or more discharge outlets arranged so as to face the opening of the magnet insertion hole, and configured to include a diameter reducing part in which an inner diameter is reduced gradually along a discharge direction of the molten resin. A diameter reducing part is arranged inside of the laminated iron core.Type: GrantFiled: February 3, 2012Date of Patent: February 10, 2015Assignee: Aisin AW Co., Ltd.Inventors: Susumu Kato, Shigeru Maeda, Takuya Ooura, Motoki Koori, Takeshi Yokoyama

Patent number: 8720039Abstract: A laminated core punching apparatus, configured such that a stator-punching press machine that has a molding die performing a partial punching gradually approaches the shape of the stator core piece. There is a punching die to punching out the stator core piece from a strip-form steel plate, and two stator lamination stations. A rotor-punching press machine and a stator-punching press machine are constructed to operate synchronously. An intermediate loop portion capable of causing a strip-form steel plate to hang down in a loop is provided in order to adjust a length of the strip-form steel plate between the two press machines, and a loop guide portion that guides a loop locus of the strip-form steel plate from above so that the strip-form steel plate does not invert is disposed above the intermediate loop portion to be capable of ascending and descending.Type: GrantFiled: March 25, 2011Date of Patent: May 13, 2014Assignee: Aisin AW Co., Ltd.Inventors: Tetsuya Matsubara, Shigeru Maeda, Atsuya Takagi, Takuya Ooura, Hajime Nishiguchi, Motoki Koori, Masahiro Hayabuchi, Susumu Kato, Keishi Ohki, Kenji Shinohara, Akio Murakami
