WIPO Patent Application WO/2014/009375
Kind Code:
A3
Abstract:
A method for reducing the development of noise in a vacuum pump (10) which is operated with a frequency converter and which has a pump motor (12) which is driven by a frequency converter (14) is characterized in that the motor current is measured and the switching frequency which is allocated to the motor (12) by the frequency converter (14) is set as a function of the motor current in such a way that the development of noise in the vacuum pump (10) is reduced.
