摘要： A wind turbine includes a dynamoelectric machine including a liquid-cooled stator and a rotor interacting with one another. The stator includes a magnetically conductive body and a winding system which is embedded in slots of the magnetically conductive body and which includes a main insulation arranged between a conductor of the winding system and a slot wall and including at least one recess provided in a cooling-channel impression of the main insulation to form at least one axial cooling channel extending between the main insulation and the slot wall, so that the at least one cooling channel borders the slot wall without insulation in direct contact with the slot wall. The winding system includes end windings which are also liquid-cooled. A can separates the stator and the rotor from one another and enables different cooling media for the stator and the rotor.

摘要： A cooling system for cooling an electric machine of a motor vehicle, including a supply line, at least one cooling line, and a bypass line. The supply line is for supplying a cooled coolant to a first winding head region of the electric machine. The at least one cooling line leads from the first winding head region through a stator of the electric machine up to a second winding head region of the electric machine. The bypass line is guided from the first winding head region to the second winding head region past the stator. The bypass line, to collect and/or discharge air, exits from the first winding head region at a highest position in a direction of gravity and/or opens into the second winding head region at a highest position in the direction of gravity.

摘要： A rotary electric machine includes a rotor shaft, a rotor attached to the rotor shaft, a stator, and a case that houses the rotor and the stator. One end side and the other end side of the rotor shaft in an axial direction are respectively supported by the case via bearings with the rotor interposed therebetween. The bearings electrically insulate the rotor shaft and the case from each other.

摘要： A cooling jacket for an electric motor comprises a fluid passage disposed adjacent to a stator and configured to convey a cooling fluid. The cooling jacket includes a flow mixing enhancer within the fluid passage adjacent an axial end of the stator. The flow mixing enhancer includes baffles, a porous fibrous structure, and/or an open-cell foam to provide greater thermal conductance at a region adjacent to the axial ends than it provides to a central region therebetween. A flow bridge directs the cooling fluid through circumferential flow paths adjacent to both of the axial ends before the cooling fluid is circulated in a central flow path around the central region of the stator. One or more nozzles direct a jet of cooling fluid upon the stator end winding, a rotor end winding, and/or printed circuit board. A ring-shaped coolant header may supply the cooling fluid to the nozzles.

摘要： The invention relates to an electric motor with an air-gap sleeve. The invention makes it possible for the first time to achieve improved heat dispersal from the rotor by means of an excess pressure in the inner region of the rotor of an air-gap sleeve electric motor. The excess pressure allows the wall thickness of the air-gap sleeve to be reduced by over 50%, as a result of which the heat transfer is improved and a gas with a high thermal capacity can be used.

摘要： A housing configuration for an electric machine includes a housing having a stator receiving region with a wall. A stator is disposed in the stator receiving region of the housing and a sleeve is pushed onto the stator. A cooling jacket surrounds the stator for liquid cooling of the stator. The cooling jacket has a radially outer cooling-jacket surface and a radially inner cooling-jacket surface with a gap between the radially outer cooling-jacket surface and the radially inner cooling-jacket surface. The wall of the stator receiving region forms the radially outer cooling-jacket surface of the cooling jacket. The sleeve forms the radially inner cooling-jacket surface of the cooling jacket. Bilaterally acting seal carriers are inserted into the gap between the radially outer cooling-jacket surface and the radially inner cooling-jacket surface. The bilaterally acting seal carriers provide an axial sealing of the cooling jacket. An electric machine is also provided.
