ELECTRICAL MACHINE ROTOR Russian patent published in 2006 - IPC H02K1/22 H02K1/32 H02K9/04

Abstract RU 2270501 C1

FIELD: electromechanical engineering.

SUBSTANCE: proposed rotor designed for use in large electrical machines, such as gas-cooled turboalternators, has slots accommodating winding separated from slot walls by means of L-shaped boxes, as well as cooling ducts provided under slots. Bottom part of insulating box resting on winding-holding slot bottom has thickened wall one of whose sides joined to bottom conductor of rotor winding is tilted to provide for wedge-shaped clearance in joint.

EFFECT: enhanced operating reliability and service life of electrical machine.
