摘要： An electric machine has a base body with a stator, a rotor shaft mounted in the base body, and a heat exchanger. Cooling ducts for a liquid cooling medium are arranged in the base body. The rotor shaft is embodied as a hollow shaft through which the liquid cooling medium can flow. The heat exchanger dissipates heat contained in the liquid cooling medium to the surroundings of the electric machine. The heat exchanger, the rotor shaft and the cooling ducts are fluidically connected in series, producing a closed circuit for the liquid medium. A feed element is arranged to co-rotate with the rotor shaft. The feed element is inserted in the closed circuit for the liquid cooling medium to forcibly circulate the liquid cooling medium in the closed circuit as the rotor shaft for the liquid cooling medium rotates.

摘要： An electric machine has a stator and a rotor arranged on a rotor shaft for rotation about a shaft axis, wherein the shaft axis defines an axial, a radial and a tangential direction. The rotor has at least one continuous axial rotor channel. The stator has a lamination stack extending over the rotor viewed in the axial direction. The lamination stack completely surrounds the rotor, forming a closed inner rotor chamber and has at least one axial stator channel running continuously in the axial direction and that is completely closed when viewed on the sectional plane. The electric machine has covers which are designed to form in conjunction with the lamination stack at least one radial channel running in the radial direction. The radial channels connect the axial stator channel(s) to the inner rotor chamber by means of a fluid connection but are otherwise closed.

摘要： An electric machine has a stator (1) and a rotor shaft (3). The rotor shaft (3) is rotatably mounted about a shaft axis (5) in relation to the stator (1), said axis (5) defining an axial direction, a radial direction and a tangential direction. A rotor (6), which is in electrical co-operation with the stator (1), is arranged on the rotor shaft (3). The rotor (6) has at least one continuous axial rotor channel (8). The stator (1) has a lamination stack (10) that extends over the rotor (6) when viewed in the axial direction. The lamination stack (10) completely surrounds the rotor (6) when viewed on a sectional plane that is orthogonal to the axial direction, forming a closed inner rotor chamber (11) when viewed on the sectional plane. A respective cover (14) is provided on both axial sides of the lamination stack (10). At least one of the covers (14) has a central cavity (15) to allow the passage of the rotor shaft (3). The lamination stack (10) has at least one axial stator channel (12′) that runs continuously in the axial direction and that is completely closed when viewed on the sectional plane. The covers (14) are designed in such a way that in conjunction with the lamination stack (10) they form at least one radial channel (16) running in the radial direction. The radial channels (16) connect the axial stator channel(s) (12′) to the inner rotor chamber (11) by means of a fluid connection but are otherwise closed. To force convection, an element (17) that acts as a fan is located on the rotor shaft (3) axially within the covers (14).
