  • Patent number: 10958048
    Abstract: A peeling device (12) includes a first peeling unit (21) and a second peeling unit (22). When an upper peeling die (33) and a lower peeling die (34) of the first peeling unit (21) are moved forward, an insulating coating (8) is peeled off from upper and lower surface of a coil conductor wire (2), and a conductive portion (7) is cut from the upper surface and the lower surface of the coil conductor wire (2). The conductive portion (7) is formed to have exposed portions (7a) and recessed portions (7b) cut in a trapezoidal shape. A front peeling die (42) and a rear peeling die (43) of the second peeling unit (22) are moved downward while the recessed portion (7b) is placed on and pressed against a second receiving section (41b) of a cradle (41), which peels off the insulating coating (8) and cuts the conductive portion (7).

  • Patent number: 10950000
    Abstract: A conductive-wire position inspecting device includes: a reference body disposed in a radial direction of a stator core; an imaging device configured to image a conductive wire and the reference body; and a calculating device configured to find a relative position and a relative angle of the conductive wire with respect to the reference body, based on an obtained image. In addition, the conductive-wire position inspecting device includes a determining device configured to determine whether or not the found relative position and relative angle are within respective permissible ranges, and if they are within the permissible ranges, determine the position of the conductive wire to be acceptable.

  • Patent number: 10556297
    Abstract: The present invention relates to a welded section examining device. In order to examine whether welding is good or bad of a welded section joining tip portions of electrical conductors projecting from slots of a stator core, a welded section examining device includes a camera, a discriminating unit, a wavelength-converting sheet, and a masking member. The camera images the welded section. The discriminating unit performs discrimination of whether welding is good or bad based on an outline of the welded section recognized from an image of the welded section imaged by the camera. The wavelength-converting sheet irradiates the welded section with a light, from a rear surface side of an imaging target surface. The masking member is interposed between the wavelength-converting sheet and the rear surface of the welded section, such that the outline of the welded section is imaged in the camera in an emphasized state.

  • Patent number: 7126246
    Abstract: Coils in respective poles are all wound in the same shape. The coils are wound such that one of the winding ends in a predetermined layers, for a single turn, is passes to an adjacent layer, or single turns at the winding ends in a predetermined layer are wound to different adjacent positions, whereby the cross-sectional shape of the coils is unsymmetrical. The coils are wound such that part of each coil crosses or contacts an intermediate line bisecting the angle formed between the axes of the coils.
