Since 1960, the Phasemaster rotary phase converter has been called “the best phase converter even built.” Others have said, “they are built like tanks”. These things remain true even today, especially when discussing the standard MA-R 240 volts models.
However, as technology changes so must some of our manufacturing designs adjust to the changes happening within the applications we convert single-phase to three-phase power.
Kay Industries Coopetion strategies expand with Phasemaster, North American Rotary Phase Converters for HVAC automatic controls and 480 volt applications.
Coopetition is a blend of the words “cooperation” and “competition”—it refers to a situation where companies that are normally competitors work together in some areas while still competing in others.
For example, two tech companies might team up to set a standard for a new type of software (cooperate), but still compete in selling their own products that use that standard (compete).
It’s common in industries like tech, automotive, and airlines—any place where collaboration can reduce costs, expand markets, or push innovation forward without eliminating the rivalry entirely.

Kay Industries, Phasemaster, and North American Rotary Phase Converters are teaming up to develop a new TMA-480v three-phase converter for agricultural 480v applications, allowing end-users who want the capabilities of a larger equipment to get the utility efficiency of smaller equipment.
In addition, the companies we be developing tempature sensing automatic control features for the HVAC industry.
By collaborating, the companies expect to offer 480 volts phase converters with semi-“digital” electronic controls earlier than they would if they worked separately, the companies explained in a recent press release.
Kay Industries is known for its phase converter expertise since 1972, and the leading seller of the Phasemaster rotary phase converter for 51 straight years. North American Phase Converter has been especially well-known among innovation enthusiasts for its Smart-Boost Phase Converter design.
According to Kay Industries, North American Phase Converters, and Phasemaster rotary phase converters the jointly-developed new controls will offer better electric efficiency while offering the same capabilities like in-rush mitigation expected of a standard Phasemaster MA-R or PL model phase converter.
The Kay Industries Coopetion announcement comes as more farming equipment, HVAC applications, and other industry machinery manufacturers continue to embrace tighter internal control, and sleek, new age-technology features.
How do I know if I need an advanced phase converter?
Simply reach out to Kay Industries. (574) 236-6220, we will gladly help you size your application set-up, then whether you need a static, rotary, digital, and some electronic hybrid, we will gladly let you know.
Miniphase Static Phase Converter, is the most affordable 1-to-3 phase conversion solution, if your application has one motor, is non-continuos, and its mechanicals are hydraulic.
Phasemaster MA-R, 240v standard rotary phase converter is ideal for equipment featuring more than one motor, continous loads, and flywheels and/or other onerous loads.
Our E-Phase department recommends Phase Perfect digital phase converters when voltage requirements are tighter. Typically, 1-2%.
Tandem phase converter and transformer solutions are recommended when both phase and voltage require a conversion.
