Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/024700
Kind Code:
A1
Abstract:
This dynamo-electric machine is provided with a stator and a rotor. The stator has a housing and a cylindrical stator core that is affixed to said housing via shrink-fitting. The rotor is rotatably provided inside the stator. The stator core is divided into two or more segments in the circumferential direction. The shapes of the surfaces along which the stator core is divided are determined such that the amount of strain that the shrink-fitting causes in the radially-outward ends of said surfaces is greater than the amount of strain that the shrink-fitting causes in the radially-inwards ends of said surfaces.
