A method and a circuit arrangement are described by means of which a stepper motor can be operated by an adaptive control across a broad rotational speed range, including standstill, in which the motor is electrically fixed in a specific rotational position and with high precision and running smoothness corresponding to a predefined motor current progression. This is essentially achieved in that the motor is operated in a low rotational speed range, including standstill, using a voltage-controlled or voltage-regulated first operating mode, and in a higher or high rotational speed range using a voltage-controlled second operating mode. |
