ABSTRACT:
A tooth coil of a concentrated winding stator includes a first layer coil arranged by successively winding a flat type wire around a tooth in a direction advancing from a proximal end portion to a distal end portion of the tooth and a second layer coil arranged by successively winding the wire around and on the first layer coil in a direction advancing from the distal end portion to the proximal end portion of the tooth. The second layer coil of the tooth coil has no turn at a most proximal end portion of the tooth corresponding to a start turn of the first layer coil, so that the tooth coil has an odd turn number.
