Abstract (en)
[origin: DE19819956A1] The invention relates to a device for regulating the rotational speed of a motor (9). The inventive device comprises a tachogenerator (10) for measuring the rotational speed and a regulating element which is configured as a parallel connection of a phase-locked loop (1) and of a frequency-locked loop (2). A time delay element (5, 6) is connected in outgoing circuit to the phase-locked loop (1) and to the frequency-locked loop (2). An adder (7) is situated between the time delay elements (5, 6) and the motor (9) in order to combine the output signals of the time delay elements (5, 6).
