1. A motor stator comprising:
- a stator core having a plurality of slots;
insulation members which are disposed in the plurality of slots; and
coils of a plurality of phases which are respectively formed by distributed-winding wires in prescribed slots of said plurality of slots disposed spaced apart at intervals of a predetermined number of slots via the insulation members,wherein the wires are disposed within the insulation members in a condition that tensions are applied to the wires, andthe stator core, the insulation members and the coils are physically fixed together by the tensions of the wires.
