Abstract: The invention relates to an arrangement for operating an electric motor, for example an electric motor for actuating a roof component, in a vehicle. Therein, the electric motor is electrically connected via at least two control lines with a motor control unit. The motor control unit is configured to control the electric motor by means of pulse width modulation. The motor control unit is configured to operate a first one of the two drive lines as an inactive line, and to operate a second one of the two drive lines as an active line during control of the electric motor. A switching module associated with the electric motor is configured to connect a terminal of the pole housing of the electric motor with the drive line which is operated as the inactive line during operation of the electric motor. The invention further relates to an electric motor as well as to a method of operating an electric motor, for example an electric motor for actuating a roof component, in a vehicle.
