7.5HP Rotary Phase Converter
Our 7.5HP Rotary Phase Converter changes input single phase power into three phase power, allowing shop equipment to operate at maximum efficiency. To ensure this is the right size for your needs please see our guide to sizing rotary converters.
7.5HP Rotary Phase Converter Features:
- Custom powder-coated steel enclosure with laser-cut knockouts for easy installation.
- Stress-free component mounts prevent damage, leakage, and failure common to banding and other compression mounting methods.
- Built-in push-button on/off switch with PowerGuard Protection keeps your investment safe in the event of a utility brownout or blackout (optional)
- Excellent electrical connections, stress-free component mounts, and bleed resistors across every capacitor for safety, longevity, and low maintenance.
- Idler generator designed and engineered specifically for phase conversion.
- The only phase converter idler generator with a Soft Start rating! Save money at the meter by using less than 1/3 of the inrush current of any stock motor (TEFC or ODP) used by other manufacturers.
- Cost only 2 CENTS per hour to operate!
- Backed by our 2/5/Lifetime limited warranty.

Sizing Help
Determine the load type of the application, and then consult the chart below. Please call us toll free at 1-888-743-6832 for sizing assistance and/or a professional recommendation.
- Easy - no flywheel, clutch, little resistance/inertia, 1-2 times full load current upon start-up
- Medium- machine inertia, medium resistance, 3-4 times full load current upon start-up
- Hard - flywheel, no clutch, starts against load, 5-6 times, or locked rotor current upon start-up
- Very Hard- elevator, hydraulic pump, equipment under continuous load etc
- Frequent Start- instant reversing, heavy running loads
- CNC - turning centers, PLC's, EDM, CNC machining
- Resistive - heaters, transformers, welders, power supplies etc.
