Abstract: An electric machine, in particular a brushless DC motor, having a stator arrangement and a rotor arrangement that are arranged coaxially with respect to one another, the rotor arrangement having a rotor body and permanent magnets embedded in the rotor body, at least one magnetic sensor for the purpose of measuring the rotational position of the rotor body being disposed at an end face of the rotor body and being located directly opposite this end face

Abstract: The invention relates to a stator arrangement for an electric machine, particularly a DC motor, comprising a stator body having a stator back yoke ring and a number of stator teeth between which stator slots to receive stator windings are formed, the stator teeth extending radially from the stator back yoke ring and stator poles being formed at the free ends of the stator teeth, the stator teeth being coupled to a sleeve, which extends coaxially to the stator body, at their free ends. The invention also relates to a method for the manufacture of a stator arrangement of this kind and a direct current motor that employs such a stator arrangement.

Abstract: 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.

Abstract: 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.
