Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/225587
Kind Code:
A1
Abstract:
A dynamo-electric machine comprises a rotor that is supported to rotate freely, and a stator core (21) placed coaxially with the rotor. The stator core is configured by laminating a plurality of steel plates (32), and has a ring-shaped yoke part (35), a plurality of teeth (34) extending from the yoke part in the radial direction, and a slot (37) provided between adjacent teeth. A stator winding is wound in the slot. The yoke part has a hole (43) extending in the lamination direction of the steel plates at a position for which the slot is extended in the radial direction, and in that hole interior, a powder compact (42) comprising a magnetic powder is provided.
