The optimal products for your wastewater treatment
Due to their design, a large number of technologies in the field of waste energy usage or mechanical energy storage require high-speed motors and generators. In addition, it must be possible to feed the electricity into the grid according to the local grid code.
Standard frequency converters are not capable of driving high-speed motors adequately as they do not provide the necessary high rotating field frequency on their own, but only with expensive additional equipment like sine-wave filters. Frequency converters by SIEB & MEYER are especially developed for the operation of high-speed motors.
They provide the necessary rotating field frequencies and ensure a low motor/generator heating by means of special control technologies without additional sine-wave filters. The motor heating has a significant impact on the system's efficiency and the service life of motors, generators and bearings.
