Document Type and Number:
Japanese Patent JP4961533
Kind Code:
B2
Abstract:
An electric machine comprising a stator having a stator winding, a housing accommodating the stator, a rotor, and an air gap having a generally cylindrical configuration. A plurality of circumferentially distributed, radial, first cooling gas ducts are provided in a stator core. Jets of cooling gas are directed to regions of an end winding which are relatively distant from the stator core, in order to achieve impingement cooling thereof. Flows of cooling gas are directed to portions of the end winding which are between the impingement cooled regions of the end winding and the respective front face of the stator core.
