CNC equipment is a very common application of the Phasemaster® rotary 3-phase converter. Kay Industries has extensive experience on a wide range of equipment from the simplest machines up through some of the most sophisticated CNC machinery. The Phasemaster rotary 3-phase converter can supply 3-phase power to a one-machine operation or to an entire shop.

Our customers include a variety of metalworking shops such as sheet metal, tool and die, precision machining, gear hobbing, welding, and stamping. The Phasemaster rotary phase converter can supply true 3-phase power to CNC lathes and mills, EDM machines (both traveling wire and sinker), air compressors, grinders, and any and all the conventional tools found in a typical shop.

Kay Industry's approach to applying phase converters on this equipment is based on careful application and sizing. In our 40 years of experience manufacturing phase converters, we have amassed a tremendous amount of application and performance data on machinery from the biggest names in the metalworking industry.

Critical Selection and Application Criteria:

Many CNC machines require a voltage regulator to keep the converter output voltage balanced over the entire load range. Supply complete details of machine electrical characteristics to factory for sizing. Oversize converters are often recommended for CNC machine tools.

Required sizing information:

The main spindle motor is the single-most important piece of information to size the converter. Always ask the manufacture to specify the main motor size in horsepower or Kilowatts. Do NOT accept an amperage value as the metric for sizing purposes.

Many offshore machines contain motors or controls components based on European or Asian voltage standards. It is vital to determine if the machine will tolerate North American voltages (240, 480, 600) or if a transformer is supplied with the machine to adapt to the foreign voltage standard.

Always verify if your site has adequate single-phase service for any equipment you plan to operate. Specifically you need at least 5amps of 240V single-phase per horsepower of simultaneously operating load equipment.
