Title:
MULTIIPHASE MOTOR AND METHOD OF PRODUCING SAME
Document Type and Number:
Japanese Patent JPS54124201
Kind Code:
A
Abstract:
An alternating current dynamoelectric machine includes a plurality of phase windings placed in stator core slots with certain slots shared by more than one phase winding and a number of those shared slots having one phase winding portion disposed in the bottom part of the slot and a portion of another phase winding disposed in the upper part of the slot near the stator bore. This another phase winding comprises a greater number of turns of a smaller diameter wire as compared to the one phase winding. In one exemplary embodiment a three phase machine has concentric windings with the third phase wound with the same number of turns as the other two phases but with each turn comprising a bifilar or two strand turn of a lesser diameter wire. This arrangement lowers the injection forces required for placing the third phase in the stator core and also aids forming the third phase windings about a temperature sensor. All three phases may be wound of wire of similar materials.
