ELECTRIC MACHINE FOR DRIVING A MOTOR VEHICLE
This abstract first appeared for US patent application 18743706 titled 'ELECTRIC MACHINE FOR DRIVING A MOTOR VEHICLE
Original Abstract Submitted
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.
