Abstract
In this stator, first and second U-phase loop windings and first and second W-phase loop windings are short-pitch wave windings, and the width in the circumferential direction of the slot between the U and V-phases in which the loop windings are disposed and the slot between the V and W-phases in which the loop windings are disposed is set to a value that is ½ the width in the circumferential direction of the slot between the W and U-phases in which the loop windings are disposed. The ratio of the first winding turns number of the loop windings and the second winding turns number of the loop windings is set so that when having added the induced voltages by the loop windings or having added the induced voltages by the loop windings in the slots, the phase difference of the induced voltages obtained by addition is 120 electrical degrees.
