Abstract
A method for detecting a rotation of a rotor of a generator, which includes measuring the voltage induced in the rotor for the generator voltage in the case of an emergency start with an inactive closed-loop controller; and detecting the rotor rotation with the aid of the induced voltage. When a rotation is detected, the control circuit is activated and the rotation is determined from the phase voltage.

A method for detecting a rotation of a rotor of a generator, comprising:
- measuring an excitation voltage at an exciter circuit of the generator;
- and
- detecting the rotation of the rotor based on the measured excitation voltage.
A control device, comprising:
- an arrangement for detecting a rotation of a rotor of a generator by:
- measuring an excitation voltage at an exciter circuit of the generator, and
- detecting the rotation of the rotor based on the measured excitation voltage.
