Magnetic wedge, dynamo-electric machine, and method for manufacturing magnetic wedge

Abstract

Provided are a magnetic wedge in which insertion of a magnetic wedge in a tooth tip of a dynamo-electric machine can be performed more smoothly, and a method for manufacturing the magnetic wedge. This magnetic wedge is installed in a slot opening of a stator of the dynamo-electric machine, and defining that the dimension of the magnetic wedge in the circumferential direction of the dynamo-electric machine is the width, the projection shape of the magnetic wedge projected on a plane perpendicular to the width direction is a rectangle, parallelogram, or a right angle trapezoid, and the corners of the rectangle, parallelogram, or right angle trapezoid have a rounded shape.

Dependencies are inferred from the claim text.
