1. An Arrangement for operating an electric motor, for actuating a roof component, in a vehicle
wherein the electric motor is electrically connected with a motor control unit via at least two drive lines;
wherein the motor control unit is configured to control the electric motor by means of pulse width modulation;
wherein when the electric motor is controlled, the motor control unit is configured to operate a first drive line of the two drive lines as an inactive line and to operate a second drive line of the two drive lines as an active line depending on the direction of rotation in which the electric motor is to be operated; and
wherein a switching module associated with the electric motor is configured to connect a terminal of a pole housing of the electric motor in each case of direction in which the electric motor is to be operated with the drive line which is operated as the inactive line.
