Rotating frequency converter produced by AEM
Rotating frequency converters are sets consisting of a drive and a
generator. Unlike transformers, rotating frequency converters are able to
realize a voltage and frequency transformation due to the combination of
machines with a differing number of poles. Typical cases are 50/60 Hz, 50/50
Hz or 60/60 Hz converters respectively. Rotating frequency converters always
allow for a voltaic decoupling as well as an effective filtration since the
primary and secondary parts are only coupled mechanically and not
magnetically.
Either asynchronous or synchronous machines are used as drives
for rotating frequency converters. However, only synchronous machines are
employed as generators. The mechanical coupling of the machines may be
carried out via belt or coupling. It is possible to install the machines
separately or to mount them together on a base frame. The output for
rotating frequency converter sets is within the complete AEM range of
production (45 kW - 4500 kW).
