  • Patent number: 11387722
    Abstract: A manufacturing method for a rotary electric machine is equipped with an insertion roller having an outer circumferential surface configured to contact a coil lead line in such a manner that the coil lead line is inserted into accommodating grooves of an insulator, a roller support section that rotatably supports the insertion roller, and a bending unit that performs a bending process to bend the coil lead line by coming into contact with the coil lead line so as to form a terminal part.

  • Patent number: 11152772
    Abstract: A cut-away cutting tool has two slit forming blade portions and a peeling blade portion interposed between the two slit forming blade portions. The two slit forming blade portions respectively form slits on an insulating coating of a flat conductor wire. On the other hand, the peeling blade portion peels off a portion of the insulating coating between the slits formed by the two slit forming blade portions.

  • Patent number: 11018482
    Abstract: The present invention relates to a method of coating-peeling and a coating-peeling apparatus. The method of coating-peeling includes a gripping step and a peeling step, and peels by a pair of peeling blades peeling target portions of an insulating coating covering peeling target side surfaces of a rectangular conductor wire. In the gripping step, abutting sections of a pair of gripping members abut on gripping target portions of the insulating coating, whereby the rectangular conductor wire is gripped between the abutting sections. In the peeling step, in a state where the rectangular conductor wire has been gripped by the gripping members, the peeling blades are moved relatively following a surface direction of the peeling target side surfaces while opposing each other sandwiching the peeling target side surfaces, whereby the peeling target portions are peeled.

  • Patent number: 10749417
    Abstract: A stator core constituting a stator at least includes first core members and a second core member. Each first core member includes a first annular portion in which slots are formed and first tab portions. On the other hand, the second core member includes a second annular portion in which the slots are formed and that is superposed on the first annular portions, and has a shape obtained by removing the first tab portions from the first core member. Electrical conductors are partially fitted in the overlapping slots.
