Frequency-Converter Brushless Generator

30-300kW, converting the input power from 50/60Hz to 400/480Hz

• Introduction

The frequency-converter generator (alternator) is extremely competitive because of the high difficulty in design and manufacturing, and the exiguous supplier sources all around the world.

It is composed of a major-frequency (50/60Hz) synchronous electric motor and a mid-frequency generator. The motor drives the generator to output the mid-frequency power.

All products are manufactured in the environments certified by ISO9001 and ISO14001, and conform to IEC60034 and Chinese GJB1213 and GJB181A standards.
