LAMINATED CORE FOR DYNAMO-ELECTRIC MACHINE

Title:

LAMINATED CORE FOR DYNAMO-ELECTRIC MACHINE

Document Type and Number:

WIPO Patent Application WO/2011/161806

Kind Code:

A1

Abstract:

A laminated core for a dynamo-electric machine comprises core segments which are annularly arranged and are stacked in the direction of the axis of the dynamo-electric machine. The core segments each have a back yoke and a magnetic pole tooth which protrudes from the back yoke. The magnetic pole teeth each have: a tooth main section provided at an intermediate section of the magnetic pole tooth; a reduced width section provided at the end of the magnetic pole tooth which is located on the back yoke side and having a smaller width than the tooth main section; and an increased width section provided at the front end of the magnetic pole tooth and having a greater width than the tooth main section. In a state in which the core segments are rectilinearly arranged in such a manner that the magnetic pole teeth are parallel to each other, the distance between adjacent reduced width sections is greater than the width of an increased width section.
