DBF400Y4Z Motor Generator Set (Frequency Converter)
50/60Hz - 400Hz Frequency Converter (Inductive Type)

** Motor Generator Set Rating Range **

- Rated Power: 5-1000kVA
- Input frequency: 50/60Hz
- Output frequency: 200-1000Hz, including 400Hz
- Output phase: 3-phase or single-phase
- Type of electric motor: 4pole inductive electric motor
- Type of alternator: 32pole synchronous brushless alternator
- Mounting structure: Common-shaft integrated overall structure

** General Introduction **

DBF400Y4Z series motor generator sets consist of a 4-pole asynchronous (inductive) motor and a 32-pole synchronous generator coupled with elastic drive discs. The units run at 1500rpm and deliver an output frequency which ranges from 400Hz no-load to 390Hz 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 of reliable excitation, precise voltage regulation, no radio interference, best voltage waveform, small size, easy operation, steady performance and long service life. They are widely used by transformer manufacturers, along with manufacturers that supply components to the aircraft, aerospace and military markets.

As options, DBF400Y4Z series motor generator sets can be mounted in a weather-proof enclosure, an acoustic-attenuated enclosure, a cargo container or a trailer.
