ABSTRACT:
An actual speed value converter for a motor comprises a tachometer having a part rotating with the speed to be measured, e.g., a capacitive or inductive rotor, or an optical actuator disk, the tachometer determining the frequency of a frequency generator. The frequency generator is part of an action path for preparing the actual speed value, the action path comprising a frequency generator and a downstream-connected frequency discriminator.
