description The invention relates to a drive system for sensitive devices, in particular for radio astronomical devices, the drive system comprising an electric motor, a converter configured to supply a drive power to the electric motor and to control a rotational speed and/or rotational position of the electric motor, a power supply line for providing the electric motor with a drive power, and a signal line for providing the converter with a signal indicating a measured rotational speed and/or rotational position of the electric motor, wherein the drive system further comprises a shaft grounding element for grounding a drive shaft of the electric motor and wherein at least one of the power supply line and the signal line further comprises a line filter unit for filtering electromagnetic interference (EMI) signals.
