ABSTRACT:
In a motor stator, teeth radially project from an annular stator core, and a plurality of slots formed between adjacent teeth are skewed. Phase windings alternately pass through slots having different skew directions, wherein the length of bridging portions, which do not contribute to generation of torque, is short and the length of the portions which are located in the slots, and which contribute to the generation of torque, is long. Further, the phase windings are bent at an obtuse angle at opposite ends of the bridging portions.
