The comparation between Rotary frequency converter and static frequency converter

1.Rotary Frequency Converter is old generation products and widely used in the 1980 Year. Static Frequency Converter is widely used in Europe,USA and China.

2. low efficiency. Rotary frequency converter motor drive generator, efficiency is about 60%--70%

Static frequency converter efficiency is 93%.

3.Rotary Converter output stability is bad, it`s output voltage and frequency by the large power fluctuations , when the grid voltage and frequency fluctuations, the rotational speed of the generator will be changed accordingly, causes the change of output voltage and frequency that causes the ship load protection or damage.

4 Rotary converter is easy to damage. Generator and motor operating reliability is poor, will wear and tear, and the need for regular maintenance, once a failure, high maintenance costs, need long time to repair.

5.Rotary frequency converter have big noise when it works. Static frequency converter do not have noise

6.Rotary frequency converter price is very high.
