The present invention relates to a DC-current electric motor (1) for a geared motor, in particular for a wiping system of a motor vehicle, comprising: - a rotor (3) comprising a collector (5), - a stator (9) comprising: - a first connection brush (B1) intended to be connected to ground (4), - a second connection brush (B2) intended to be connected to a voltage source (6) and associated with a first rotational speed of the electric motor (1), - a third connection brush (B3) intended to be connected to a voltage source (6) and associated with a second rotational speed of the electric motor (1) different from the first speed, the connection brushes (B1, B2, B3) being configured so as to come into contact with the collector (5) of the rotor (3), - a switching unit (8) for selectively supplying power to the second (B2) or the third (B3) connection brush depending on a command from a user, the electric motor (1) also comprising - a measurement unit (17) configured so as to measure the voltage between the third connection brush (B3) and ground (4) when the second connection brush (B2) is supplied with power or so as to measure the voltage between the second connection brush (B2) and ground (4) when the third connection brush (B3) is supplied with power, - a processing unit (19) configured so as to determine the position of the rotor (3) from the variations in the measured voltage.
