Abstract: An electrical machine has a machine housing accommodating a rotor, a stator, and an output shaft. A venting element has a collecting chamber, an inlet, and at least one outlet, where the inlet is connected to the interior space of the housing, within which air can expand and increase in pressure when the electrical machine heats up during operation. The outlet(s) of the venting element connects to an external environment. The collecting chamber is between the inlet and the outlet(s) and is connected via the inlet to the interior of the housing and via the at least one outlet to the environment. The venting element connects the interior to the environment so that air can escape from the interior via the inlet, the collecting chamber, and the outlet(s) to the environment when the internal pressure is higher than the pressure of the external environment.

Abstract: An electrical machine has a housing (2), a stator (3) arranged in the housing (2) in a rotationally fixed manner, and with a rotor (4) mounted so that the rotor (4) can rotate in the housing (2). A degree of freedom is provided, in the radial direction, between the housing (2) and the stator (3) so as to permit material-related thermal expansion differences between the housing (2) and the stator (3) in the radial direction. Throughout the operating range of temperatures encountered during use, the stator (3) is held in the housing (2) and is aligned concentrically with the rotor (4) by the interlocking connection elements (5). The interlocking connection elements (5) are designed and arranged in such manner that the housing (2) can expand and contract, in a stress-free manner, relative to the stator (3). In addition the electrical machine is arranged in a vehicle transmission.
