Abstract: The disclosure relates to a direct current electric machine comprising a housing, a rotor having coils configured as electromagnets, and a stator with stator magnets. The rotor and the stator are positioned inside the housing. The electric machine also comprises sliding contacts configured to conduct current which is to be conducted through the coils of the rotor, as a commutator. The electric machine further comprises an interference suppressor configured to suppress electrical interference that emanates from the direct current electric machine. The interference suppressor is positioned outside of the housing.

Abstract: A control unit according to the invention is particularly intended for internal combustion engines for motor vehicles. With known control units, great effort is required if the customer requests a different electric assignment for the electrical connection. With the control unit according to the invention, any arbitrary electric assignment of the pins can be achieved by simple measures at the electrical connection. This considerably simplifies meeting special customer requests.
