Claim:
1. A stator comprising: 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 in a concentrated manner via the first winding units and the third insulator while allowing a first crossover wire to pass through the first crossover wire guide; a second teeth unit including a second insulator having an annular second crossover wire guide and a plurality of second winding units radially provided at regular intervals on an outer circumference of the second crossover wire guide to cover teeth of the other phase group of the alternating current, the teeth of the other phase group having upper halves fitted to the second winding units, a third insulator that covers lower halves of the teeth, and a winding wire of other phase wound around the teeth of the other phase group in a concentrated manner via the second winding units and the third insulator while allowing a second crossover wire to pass through the second crossover wire guide, the plurality of second winding units being inserted into between adjacent ones of the first winding units, respectively, and the second crossover wire guide being superposed on the first crossover wire guide in an axial direction thereof; and an annular yoke including a plurality of recesses at regular intervals on an inner circumference thereof to fit and fix the teeth of the one phase group and the teeth of the other phase group alternately to the recesses.
