Abstract
PURPOSE: To better the ventilation cooling of a rotor under high speed revolution, by cutting threads with a number of starts on a surface of the rotor in a revolving electric machine for liquid cooling a stator by sealing a surface of the stator facing to the rotor by means of an insulating material.
CONSTITUTION: The pawl-shaped magnetic poles 11 of a rotor 10 are integrally formed holding a non-magnetic material while threads 15 with a number of starts are cut on the surfaces in the same direction as the direction of rotation. A ventilation inlet 14a and a ventilation outlet 14b for cooling wind are mounted to a bracket 14. With the stator side, a shield layer 9 by an insulating material is pasted to a void portion facing to the rotor 10, and the stator is cooled by flowing a cooling medium toward a hole 1b from a hole 1a under a condition that the stator side is separated from the rotor side. Consequently, air among voids around a core is pushed out to the ventilation outlet 14b from the ventilation inlet 14a by the pumping action of threads 15 cut on the surface of the rotor 10, thus controlling the temp rise of the surface of the rotor 10 while preventing vibration due to the local thermal deformation of the core.
