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 thethird 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 thethird connection brush (B3) is supplied with power, and a processing unit (19) configured so as to determine the position of the rotor (3) from the variations in the measured voltage.

    本发明涉及一种用于齿轮马达,特别是用于机动车辆的刮水系统的DC电流电动马达(1),包括:‑转子(3),包括集电器(5),‑定子(9),包括:‑第一连接刷(B1),其旨在连接到地(4),‑第二连接刷(B2),其旨在连接到电压源(6)并与电动马达(1)的第一旋转速度相关,‑第三连接刷(B3),其旨在连接到电压源(6)并与电动马达(1)的不同于第一速度的第二旋转速度相关,所述连接刷(B1、B2、B3)配置成与转子(3)的集电器(5)接触,‑开关单元(8),用于基于来自用户的命令选择性地向第二(B2)或第三(B3)连接刷供电,所述电动马达(1)还包括:‑测量单元(17),其配置为在第二连接刷(B2)被供电时测量第三连接刷(B3)和地(4)之间的电压,或者在第三连接刷(B3)被供电时测量第二连接刷(B2)和地(4)之间的电压,‑处理单元(19),其配置成根据测量电压的变化来确定转子(3)的位置。
