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.
