General Introduction

the ADBF400Y4 series Motor Generator Sets consist of a 4-pole induction motor and a 32-pole synchronous generator. the motor and the generator are mounted on the common shaft (integrative mounting) and operate at the speed of 1500rpm. the products are designed for airport ground power units which require a clean 400Hz power output converting from the 50Hz grid line.

the ADBF400Y4 Motor Generator Sets are rated for continuous duty. They have prominent technical advantages on 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.

as an option, ADBF400Y4 series Motor Generators can be mounted with a weather-proof enclosure, an acoustic-attenuated canopy or a trailer.
