Introduction
Rotary Frequency Converter (Motor Generator Set) consists of a 10-pole Brushless Synchronous Motor and a 10-pole generator. The motor and the generator are mounted on the common shaft (integrative mounting) and operate at the speed of precise 600rpm. The products are designed for the applications which require a clean & accurate 50Hz power output converting from the 60Hz grid line.
The Rotary Frequency Converter have prominent technical advantages on precise frequency output, low operation noise, reliable excitation, precise voltage regulation, outstanding voltage waveform, compact size, easy operation and no radio interference. They also have the high overload capability, best transient characteristics and rugged fabrication, which make them suitable for the applications where continuous service in a harsh environment is required.
Rotary Frequency Converter can be mounted with a weather-proof enclosure, an acoustic-attenuated canopy or a trailer.
