Rotary Phase Converters

True 3 phase Rotary Phase Converters scored the highest in all categories of our testing and research.  Quality 3 phase Rotary Phase Converters use a balanced 3 phase generator with power factor correction, resulting in balanced safe 3 phase power that is better than even standard utility supplied 3 phase power.  

When properly installed, Rotary Phase Converters were extremely safe to operate.  Due to high quality materials such as copper windings and quality parts, with standard maintenance, a quality Rotary Phase Converter should operate indefinitely (35 years and more).  There are thousands of rotary phase converters installed in the US that have operated over 50 years.  The balanced 3 phase generator and power factor correction ensure that the output is a smooth balanced 3 phase wave form that will be completely safe for the 3 phase machinery it is meant to operate. 

Note: In our research we found that some companies called a product that they sold a "Rotary Phase Converter" but, in fact, their product is made with just a control box (or a Static Converter) and an electric motor.  These type of products were shown though our rigorous testing to be unsafe and unreliable.  There is a tendency for these "Static Phase Converter" controlled units to burn out the equipment it is meant to operate due to phase imbalances that change with the load.  We did not count these types of products as true Rotary Phase Converters, but rather in the category of Static Phase Converter or Build Your Own Phase Converter Plans.

It is recommended that only true 3 phase balanced Rotary Phase Converters, with a 3 phase generator and power factor correction, is used to power 3 phase machinery and equipment.  True 3 phase Rotary Phase Converters produce excellent 3 phase power which can be used to power any application.  Rotary Phase converters are used to power all types of loads from lasers, ovens and motor loads to CNC and circuit type loads.

Remember that not all rotary phase converters are manufactured to the same high quality standards.  Click here to read our Phase Converter Purchasing Checklist for guidance in selecting a quality product from a quality company.
