Rotary Converters ... aka Phase Converters
Convert single Phase Power to 3-Phase Power
Click for <> 1 to 10 HP <> 15 to 50 HP

We have negotiated a partnership to bring You Phase-A-Matic
.... the best in Rotary Phase Converters

Heavy Duty Rotary Converters
These Converters will Start motor loads up to Name Plate rated Horse Power (HP)
These Converters will Operate motor loads up to 3x Name Plate Rated Horse Power (HP)
(Start Largest motor First - - Then Start other motors, One at a Time)
(Extremely high start up Loads may require an Oversized Converter)

CAUTION ! !
Always Start Converter Before Applying Load
All electrical work to be done by Qualified Electrician
1. Magnetic Controls or single-phase loads (including electronics, microprocessors, etc.) must always be energized by Lines T1 and T2
2. Never connect a ground or neutral to Line T3 (the manufactured phase). Line T3 can easily be identified as the line with the highest voltage to ground with the converter running. Properly ground all electrical equipment
3. It is essential that careful consideration be given to your wiring length and size to prevent slow starting due to a voltage drop. Consult the National Electrical Code for proper wire sizing.
4. Due to the high starting current (in-rush current) common to electric motors, a drop of starting torque may occur when using a rotary converter that is too small. Because of this, it is NOT advised to size an application HP for HP. The vast majority of applications require sizing the rotary converter 50% larger or more than the largest HP rated motor of your equipment. Contact Phase-A-Matic for further details if any question should arise.
5. Tables above show approximate idle current at 230V. Higher line voltage will cause idle current to increase. Excessive amperage could also be caused by incorrect installation.
6. Converter should reach full speed within 2 to 3 seconds.
7. Lubricate every 12 months for normal operation, or every 6 months for continuous (24-hour). Use high-temp bearing grease: Exxon POLYREX^rpolyurea grease or equivalent. Available from Phase-A-Matic, Inc.
8. Voltage sensitive equipment (CNC/PLC, 3-phase powered electronics, etc) may require a Phase-A-Matic voltage stabilizer designed to reduce phase voltage imbalance. Refer to Voltage Stabilizer brochure or Call Phase-A-Matic @ 1-800-962-6976

Note 1. LARGEST MOTOR HP: Almost all machines require sizing the Rotary Converter 50% larger (or more) than the largest HP of your equipment.
Note 2. MULTIPLE MOTORS LIGHTLY LOADED: HP shown in above charts reflects maximum HP allowable under specific conditions. Example: Multiple motors, not started at the same time, that are lightly loaded. Questions? Call Phase-A-Matic @ 1-800-962-6976
Note 3. MINIMUM SINGLE-PHASE SUPPLY: Single-phase current shown in above tables is single-phase line current drawn for absolute maximum rotary converter loading or output. Since rotary converter should always be oversized by 50% (for high starting current), it is not usually necessary to size single phase breakers to the chart current. For smaller single phase breaker questions, Call Phase-A-Matic @ 1-800-962-6976.
