50Hz-400Hz Rotary Frequency Converter (Motor Generator)\

** General Introduction **

DBF400T4 series motor generator sets consist of a 4-pole synchronous motor and a 32-pole synchronous generator mounted on a common shaft and inside a common frame. The units run at 1500rpm and deliver an output frequency of precisely 400Hz from no-load to full-load.

The products are rated for continuous duty. They provide a clean source of 400Hz power isolated from switching transients, voltage fluctuations and power line noise. They have prominent technical advantages with reliable excitation, precise voltage regulation, no radio interference and best voltage waveform, and advanced integrated structure with the superiorities of small size, easy operation, steady performance and long service life. They are widely used in naval and air force bases, missile and ground support installations, radar and communication test sites, airports and university laboratories. They also have high overload capability, outstanding dynamic characteristic and rugged fabrication which make them ideally suited for military applications where continuous run time in a harsh environment is required.
As an option, DBF400T4 series motor generator sets can be mounted in a weather-proof enclosure, an accoustic-attenuated enclosure, a cargo container or a trailer.
