GENTEC Baldor Partnership
The single largest component in a phase converter is the American Rotary Soft Start Generator. American Rotary's engineering departments spent over 2 years engineering the perfect generator for a Rotary Phase Converter, and its patent technology is the best in the industry. American Rotary's custom generator is one of a kind in our industry and outperforms the standard motor/idlers found on a typical phase converter.
-
Designed for Phase Converters
American Rotary's custom designed generator uses only 1/3 of the starting current to get the generator started and unlike traditional off the shelf three phase motors they are capable of running 24/7 with no duty cycle. In addition, unlike many competitors that use a three phase motor that have the shaft removed, our generators provide precise power and run cooler, which in turn will extend the life of your idler.
-
Stable Voltage and Sinewaves
The induction generator, by design, balances the power factor and phase angle which ultimately leads to true, undistorted sinewaves and more stable voltage. Typical phase converters that use modified motors have distorted sinewaves resulting in harmonics causing high operating temperature on the load motor, putting undue stress on your equipment.
-
Open Design (ODP) vs. Enclosed Design (TEFC)
Major manufacturers like American Rotary, Phase-A-Matic, Ronk, and Kay use Open Drip Proof (ODP) style designs. Open designs run cooler, quieter, use less power and can maintain voltage better than TEFC Designs. Only trust Open Drip Proof designed phase converters to run your valuable equipment.
-
Voltage Stabilization
A screen shot of an oscilloscope shows the difference in voltage drop using a modified 3-phase motor (GREEN) vs. using a American Rotary Soft Start Generator (RED). This is especially important when running voltage sensitive equipment such as CNC machines, welders and other rectified or computer loads. Stable voltage keeps your equipment protected and running perfectly.
-
Built-in Magnetic Starter
American Rotary's magnetic starter provides the means to continuously control your American Rotary phase converter remotely, from multiple locations or in conjunction with automatic equipment. See the Expandable Design – Remote Start Feature for more information on remote start options.
-
Quality Control
The American Rotary manufacturing team assembles its starter modules using torque drivers that are tested and certified as a requirement for UL certification at our Wisconsin manufacturing plant. Every control panel American Rotary builds passes over 50 criteria for quality certification before it ships your new phase converter to you!
-
Designed for the Hardest Start Ups
American Rotary starters are custom designed to meet even the most difficult loads and the most stringent standards. We oversize the starters to ensure they can handle the entire starting current and continuous load. All American Rotary phase converters undergo rigorous simulation and testing in its R&D department to ensure your equipment and operators are safe and protected.
-
Be Safe and Aware!
A starter is not designed or rated to be the safety disconnect. Be aware of phase converters that claim their starter disconnects all three lines of output. A properly used starter only controls the start/stop of the phase converter and does not disconnect the single phase lines. American Rotary will always put your safety first.
-
Double or Triple your power!
All American Rotary Phase Converters are capable of phase synchronization for increased capacity. Converters can be daisy chained together to double, triple, quadruple your power. Call or email the American Rotary technical staff for more information on available options.
-
