  • Stator for rotary electric machine
    Patent number: 10063118
    Abstract: The rotary electric machine includes concentrated winding coil that is configured by winding a conductor wire around a tooth for multiple laps so as to pass through a concave space that is formed by trunk portions and first and second flange portions of first and second insulators, a crossover points of the conductor wire being formed on a coil end of the concentrated winding coil that is positioned above the first insulator, slot-housed portions of the concentrated winding coil that are positioned on two circumferential sides of the tooth being configured such that the conductor wire is arranged in a staggered stacking pattern in multiple rows and in multiple layers, and a varnish being applied to the coil end that is positioned above the first insulator.
    Type: Grant
