The rotary portion of converter is proprietary, custom built to specifications by Baldor Electric, one of the largest and most trusted motor manufacturers in the world. It is a true phase converter and not a modified electric motor as most of competitors use. Many years of testing, changing and developing the converter in conjunction with Baldor's engineers has produced a very simple and trouble-free converter with extremely low idle current and low noise level.
Simplicity of design; uses all soldered connections
Keeping the design exceptionally simple reduces the risk of electrical connection failure to almost zero since these are some of the most common causes of failure.
The Rotor
The Phase-A-Matic™ failure rate is practically zero because the rotors are specifically designed and manufactured for rotary converter use. However, some of competitors emphasize that rotors often fail. This is because they machine standard electric motors, modifying and thereby weakening standard electric motor rotors, which were not originally designed to be used as a phase converter.
The Rotary Converter is designed to supply full running current to a three-phase motor normally providing it with full running torque. However, most motors will draw five times their running current during start-up. When used at its maximum HP rating the Rotary Converter cannot deliver the full (5 times) starting current to the motor and therefore cannot provide full starting torque. For heavy start-up loads a larger converter should be used. Below are the minimum size recommendations for various applications.
