  • Stator, motor, blower, and stator manufacturing method
    Patent number: 9608491
    Abstract: A stator includes a first teeth unit including a first insulator having an annular first crossover wire guide and a plurality of first winding units radially provided at regular intervals on an outer circumference of the first crossover wire guide to cover teeth of one phase group of an alternating current, the teeth of the one phase group having upper halves fitted to the first winding units, a third insulator that covers lower halves of the teeth, and a winding wire of one phase wound around the teeth of the one phase group, a second teeth unit having an identical configuration to that of the first teeth unit in which a winding wire of the other phase is wound in a concentrated manner, with second winding units inserted between adjacent ones of the first winding units, and an annular yoke including a plurality of recesses at regular intervals.
