Abstract:
The invention relates to a vacuum pump drive including an electric motor driving the rotor of a vacuum pump, a first frequency converter connected to the electric motor and designed to generate a motor input voltage for driving the electric motor from a network supply voltage, at least one second frequency converter that is also designed to generate a motor input voltage of a variable frequency from a network supply voltage, in order to drive the motor according to the frequency of the motor input voltage, characterized in that the second frequency converter is provided with a measuring device, which is provided for measuring the motor input voltage generated by the first frequency converter and/or the related motor input current, in order to synchronize the second frequency converter with the first frequency converter.

Claim (Index 5):
The vacuum pump drive of  claim 1 , wherein the second frequency converter is configured to generate the motor input voltage based on the measured values of the measuring unit.
