The difference between a rotary phase converter and a static phase converter is that the rotary phase converter actually produces three phase power much in the same way as the utility companies.  A static phase converter does not produce true, three phase power.  It works by changing and discharging capacitors to produce a third phase of power only a few seconds during the startup of a motor.

Phase converters have been used for decades, and the simplest is a static phase converter. Because they do not produce true, three phase power, it is guaranteed that a static phase will do a poor job of balancing the voltages of a motor. Motors can only run for short periods of time on a static phase converter and does not have the capabilities of running motors at full horsepower. Static phase converters require the motor to be significantly derated. Typically, the motor will only receive between 60 and 80 percent of its normal operating power. Another problem with a static phase converter is that it can only run one piece of equipment at a time.  The only time a static phase converter should be used is for small horsepower, single-motor applications.

The reason why static phase converters are still so popular is that they are inexpensive. It is very sad when you see someone buy a static phase converter for the operation of their very expensive equipment, and then their equipment becomes damaged, or worse, ruined because of overheating caused by the static converter.

The reason static phase converters are not used more widely is due to the fact that they produce malfunctions from the beginning resulting in a shorter life span of the motor due to voltage and current imbalance.

Also, static phase converters produce harmonics that pollute the power grid and damage equipment.  They  are not strong enough to operate sensitive equipment or multiple loads.

Manufacturers have corrected these problems by inventing quality rotary phase converters. Rotary phase converters are reliable and flexible. They produce true, three phase power enabling them to run any type of load, and you can use them to operate a combination of motors.

One word of caution, many companies are calling their products rotary phase converters, but they are nothing more than a static phase converter with a motor. Make sure you are getting a true, three phase rotary converter by selecting a reputable manufacturer.

ACE Phase Converters have become our best recommendation because of their high standards and quality phase converters. When buying a phase converter, check the warranty.  If a company is offering a five-year or more warranty, you are probably getting a true, rotary three phase converter. But beware, if a company is only offering a one or two-year warranty, this usually means a company is selling a less quality converter such as a static phase converter with a motor. Protect your investment by investing a little more, and you will be rewarded with years of quality service.  Your equipment will not be damaged by malfunctions and equipment burnout because of a less quality converter.  You will save money due to increased production and  higher revenues.
