A motor housing for an electric motor having a housing shell which encloses a space to accommodate the electric motor, and a flexible partition in the housing shell which separates a pressure equalizing cavity from the cavity accommodating the electric motor, whereby the pressure equalizing cavity is connected to the outside environment.

Motor housing for an electric motor

The invention relates to a relay supporting unit for an electric motor to arrange a number of relays at the end of the electric motor, at which winding connections and signal lines of the electric motor are provided. The relays are used to connect and interrupt the power supply to the motor windings. The relay supporting unit according to the invention features a supporting component which is designed in such a way that it extends over the end of the electric motor and has at least one, preferably several, chambers to accommodate and position the relays. A connecting frame is integrated into the supporting component to electrically connect the winding connections and the relays. Furthermore, a sensor PCB is also preferably integrated to which the signal lines of the electric motor can be connected. With the relay supporting unit according to the invention, it is possible to pre-assemble high-voltage bearing electronic components to control the motor winding of the electric motor as well as low-voltage bearing electronic components to record the signals of the electric motor in one single component.
