ABSTRACT:
In order to control the rotation speed of an output shaft (2) driven by an electric motor (3) by means of a gear mechanism (1), the difference of the rotation speeds of the motor shaft (4) of the electric motor (3) and of the output shaft (2) is measured by means of an incremental torque meter (5, 6, 8, 9, 10) as an actual value and is used in a control circuit for controlling the electric motor (3) in order to level deviations of the rotation speed of the output shaft (2) from a specified desired value.
