  • Rectangular wire stator coil manufacturing method
    Patent number: 9825513
    Abstract: A rectangular wire is wound on a stator core having a plurality of teeth and a plurality of slots. A plurality of rectangular wire elements is provided by cutting a rectangular wire into a predetermined length and bending into a substantial U-shape. A plurality of rectangular wire pieces configured to form a coil by connecting predetermined end portions of the rectangular wire elements is molded as a sub-assembly. Each of the plurality of the rectangular wire elements is inserted into a predetermined pair of the slots from a first end face of the stator core such that the respective end portions of the rectangular wire elements project from a second end face of the stator core. The rectangular wire pieces of the sub-assembly are fixed to the end portions of the rectangular wire elements, thereby manufacturing a stator coil having compact coil ends easily.

  • Magnet evaluating device and method
    Patent number: 9625539
    Abstract: A magnet evaluating device evaluates an evaluation magnet by passing the evaluation magnet, which is formed by connecting a plurality of magnetic sections with insulating material in between, and a master magnet of the same form through an alternating magnetic field generated by an excitation coil, measuring the eddy current occurring in the magnetic section as voltage or current occurring in a detection coil and comparing the measured value for the evaluation magnet and the measured value for the master magnet.
