Title:
ステータのエンドターンの磁束を利用する誘導電動機
Document Type and Number:
Japanese Patent JP2009516497
Kind Code:
A
Abstract:
An induction motor includes a stator having stator cores and coils wound on the stator cores to leave end-turns, and a rotor rotatably provided at an inner side of the stator with a gap left between the stator and the rotor. The rotor has a rotor core provided at an axial end with an end-turn utilizing portion extending radially outwardly in a confronting relationship with the end-turns of the stator with a gap left therebetween, so that magnetic fluxes generated in the end-turns flow through the end-turn utilizing portion of the rotor core. The rotor core is made of compressed soft-magnetic powder.
