Baldor Electric/Phase-A-Matic™ Design: 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, with warranty stations nation and worldwide. 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 relatively low noise level. Many of customers confirm that rotary converters are the quietest and most trouble-free available, compared to other converters on the market.

Simplicity of design: 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. We use only soldered connections with no mechanical electrical connections like spade clips, terminals or screws which can vibrate loose or corrode over time. There are no start capacitors, relays or contactors with connections which can come loose or arc and weld the contacts causing failure of the contactor and the start capacitors, and perhaps even the rotary converter or your equipment. Because of this we do not have circuit board failures caused by spikes generated by the magnetic contactors as some of competitors do.

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.

Testing before shipment: Every converter is performance tested before shipment and assigned a serial number. These records are kept for review if any questions should ever arise about the performance specifications.

MTBF (Mean Time Between Failure): Failure rate (MTBF) is so low it's almost impossible to determine. We find that within the first 12 months approximately 1 in 150 might have a problem, and usually within a few weeks or months. After the first 12 months, it might be one or less in 5,000 over a 30 year period. We continue to hear of Rotary Converters that have been in service for 25 or 30 years, and which are still working flawlessly. It could go on to do another 25 or 30 years. There is very little to go wrong with the Rotary Converter.

Multiple Motor Applications: Due to the high in-rush current required to start a motor, which can be as much as 5 to 10 times the normal running current, most applications require sizing the horsepower (HP) of the Rotary Converter 50% larger, OR MORE than the HP of the largest motor, or any combination of motors started at exactly the same time. The first motor started, IF NOT RUNNING HEAVILY LOADED, generates additional 3-phase power back into the circuit. You can then run additional motors (not heavily loaded and not all started at the same time). A maximum of up to 3 times the HP rating of the Rotary Converter can run at the same time, if not heavily loaded, and not started simultaneously. For example, a 3 horsepower converter could run motors totaling up to 9 horsepower under the specific conditions described here. See Installation.
