General Introduction

the ADBF50T12 series Motor Generator Sets consist of a 12-pole brushless synchronous motor and a 10-pole synchronous 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 ADBF50T12 Motor Generator Sets are rated for continuous duty. They 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.

as an option, ADBF50T12 series Motor Generator Sets can be mounted with a weather-proof enclosure, an acoustic-attenuated canopy or a trailer.
