Keeping jobs at home not only helps our economy, but it is critical for quality control and for the customer serivce American Rotary provides for all our customers.
American Rotary's breakthrough design of the MicroSmart™ controller (AD, ADX) allowed it to create the first true digitally controlled phase converter in the industry. Its digital accuracy provides an impressive ability to adapt to changing loads, sagging voltages and gives our phase converters the feel and performance you expect from high precision machines.
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.
American Rotary's custom designed generator features a Soft Start using only 1/3 of the starting current to get the idler generator started unlike the traditional off-the-shelf 3 phase motors found in typical motors with shafts removed found in typical phase converters. This generator provides precise power, runs cooler for longer life and can run continuously from a no load condition through full load.
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.
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.
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.
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.
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!
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.
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.
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.
As you add more equipment or change the type of equipment you run, the MicroSmart™ controller adapts with your shop needs. Powering your shop or business with a SMARTConverter™ (AD, ADX) ensures your equipment gets the right power at the right time, even as your business changes and grows.
All American Rotary Phase Converters are designed to work with wired and wireless remote starts. Our long range radio frequency remote starter and receiver works seamlessly with our latching full current magnetic starter to remotely control your converter. Wireless remotes feature 500’ range and include high gain, omni directional antenna and a key FOB or wall mount transmitter. You can also control your converter with our wired remotes!
American Rotary realizes that some equipment just isn’t meant to be hard wired. So it gave every phase converter a space for a twist-lock, 3-phase receptacle and a flush mount 3-phase breaker Great for welders, battery chargers, mobile jobsite converters and more.
Designed to meet UL minimum space requirements, American Rotary enclosures have removable sides so that the oversized terminal blocks can be accessed with ease. The cover is hinged and can be easily removed.
Copper Aluminum Alloy and Nylene terminal blocks are specifically designed and molded for American Rotary phase converters in order to provide easy organized connections for a carefree, UL compliant installation. Terminal blocks are clearly marked for trouble-free installations.
No drilling or punching needed! All the necessary knockouts for installation are provided and powder coated to prevent rust. The knockouts are sized for the maximum anticipated conduit for proper wire gauge per NEC.
The design flexibility and time savings features that laser cut steel provides is an important part of the quality of an American Rotary phase converter. From knockouts for breakers and receptacles, to perfectly mitered corners, laser manufacturing results in a longer lasting, better quality product.
The American Rotary MicroSmart™ Controller is a patent technology which provides precise control of the phase converter. It monitors the voltage every 50 milliseconds providing better voltage control, prolonging the life of the converter, handles significantly more load capacity (ADX and AI), and enabling several failsafe features that are only available on American Rotary’s SMART Series™ phase converters. (AD, ADX, and AI units only)
Smart Series™ digital rotary phase converters (AD, ADX, and AI) run on our MicroSmart™ Controller. This custom designed microprocessor delivers the right power at the right time in both start-up and run mode. The MicroSmart™ controller monitors and takes a sampling of the voltage every 50 milliseconds on all three lines of the output voltage.. (AD, ADX, and AI units only)
American Rotary has invested extensively in research and design to create the state of the art MicroSmart™ Digital Controller. Other so called “digital” rotary phase converters use an off the shelf voltage relay that does not monitor the voltage like the MicroSmart™ Controller. (AD, ADX, and AI units only)
All American Rotary Smart Series™ phase converters are designed to grow with your business. Our converters are engineered to allow numerous upgrade options, including; Hardware, Software and Kit upgrades. You can also run our phase converters in parallel and double your power to adapt to your changing needs. Need more power? More precise power? Just turn on your American Rotary Smart Series™ and let our technology do the work. (AD, ADX, and AI units only)
High inertia and high friction loads such as air-compressors, blower, fans, flywheel & lifting loads can draw 6 times FLA (full load amps) for several seconds during start up. The CTR acts as a stabilizer, ensuring consistent voltage and current. CTR allows our ADX and AI phase converters to start your high inertia machinery with ease in about 1/3 the time of a standard phase converter. (ADX and AI units only)
American Rotary leads the industry with its innovative CTR technology. CTR (Current Transient Reactor) along with the MicroSmart ControllerTM allows high currents to be drawn through the phase converter producing more torque while maintaining voltage and power. (ADX and AI units only)
American Rotary's proprietary CTR technology provides a layer of protection against external transient current spikes on the incoming single phase line at start up. Our CTR technology allows us to offer the best phase converter warranty in the industry. (ADX and AI units only)
