    摘要： The invention relates to a two-phase electronically-commuted DC-motor, comprising a permanent magnetic rotor (36), terminals (28, 30) for connecting the motor to a power supply (22) and a stator (102) with a winding arrangement. The above has a first winding phase (52), provided with a first controllable semiconductor circuit (70), for control of the current in the first winding phase (52) and a second winding phase (54), provided with a second controllable semiconductor circuit (80), for control of the current in the second winding phase (54). The first and second semiconductor circuits (70, 80) together define a partial amount of semiconductor circuits for the electronic commutation. The motor also comprises a third controllable semiconductor circuit (50), arranged in a line from one of the terminals (28, 30) to the winding (52, 54), a device (74) for prevention of a reverse current, arranged in a common line to the semiconductor circuits (70, 80) of the partial amount and an arrangement for carrying out the following steps: depending on a desired operating condition of the motor (20), the third semiconductor circuit (50) is alternately blocked and activated without switching the semiconductor circuit from the partial amount currently in a conducting state off, such that, during operation, following a blocking of the third semiconductor circuit (50), a decaying ring current (i2, i3), flows through the semiconductor circuit from the partial amount currently in a conducting state and the other semiconductor circuit from the partial amount or a recovery diode (76, 81 ), provided therein and through the first and second winding phase (52, 54), generating a torque on the motor when the energy from the power supply (22) is temporarily interrupted.
