DBF Rotary Frequency Converters (Motor Generators)
** General Introduction **

The DBF series rotary frequency converters consist of an electric motor (inductive motor or synchronous motor) and a synchronous generator mounted on the common shaft and the common frame. The input frequency can be 50Hz or 60Hz, while the output frequency ranges from 50Hz to 1000Hz depending on different market requirements. They are our original designs with no other suppliers in China. All products are designed and manufactured in strict compliance with IEC, ISO, and other international standards, as well as the related military standards.
The products can be mainly devided into the following three types:
(1) Rotary frequency converters from 50Hz to 60Hz (or from 60Hz to 50Hz)
(2) Rotary frequency converters from 50/60Hz to 400Hz
(3) Rotary frequency converters from 50/60Hz to other medium frequency of 200-1000Hz

The products are featured with best output waveform in China (with the harmonic distortion less than 2%), top electrical performance, high reliability, long service life,
compact appearance, as well as most competitive pricing in the industry. They have been supplied to both military market, domestic markets and international markets
with the well-acknowledged top quality level. To get more info, please contact us today.
