Choose with confidence
Start with the machine, not a model number.
The right converter depends on motor horsepower, starting behavior, voltage, and what may run at the same time. A few nameplate details are enough to build a confident shortlist.
Start the 60-second sizing guide- 1Check the nameplate
Record motor horsepower, voltage, phase, and full-load amps.
- 2Identify how the load starts
Compressors and other hard-starting loads often need additional capacity.
- 3Confirm the complete system
Review simultaneous loads, controls, transformer needs, and available service.
One platform, several workflows
Pick the control style that fits your shop.
Choose the horsepower first, then match the model family to how your equipment is used.
PL · Push-button control
Integrated start and stop control for convenient manual operation.
AutoStart · Demand sensing
Automatically starts and stops conversion power as equipment demand changes.
DualZone · Lower inrush
Staged starting helps reduce startup demand where single-phase service is limited.

Pro tip: Cheap converters can damage CNC machines and void equipment warranties. The $200 saved now could cost $5,000+ in repairs.
Choose the right technology
Rotary vs. digital — the technology difference
VFD and digital converters can look good on paper. Here is what happens in real shop conditions.
Rotary phase converters
- 25+ year lifespan— Built with cast iron and copper
- Five-star durability— TEFC heavy-duty motors
- Run multiple machines— Simultaneously, no problem
- Handles all load types— Inductive and resistive
- Works with transformers— No compatibility issues
- AutoStart available— $0 idle-cost option
Ideal for CNC machines, lathes, compressors, welders, and wide-belt sanders.
Digital and VFD converters
- 5–7 year lifespan— Electronic components fail
- Lower durability— Sensitive to dust and heat
- One machine at a time— Limited capacity
- DC leakage issues— Requires filtering
- Not for transformers— Compatibility problems
- Constant standby draw— Always using power
Best for quiet environments, medical equipment, and single-machine setups.

Common questions
Know what matters before ordering
How do I choose the right horsepower?
Start with the largest motor and account for its starting load, voltage, and any equipment that may operate simultaneously. Use the sizing guide or call Phoenix for confirmation.
Can one converter run multiple machines?
Many rotary systems can supply multiple compatible loads when the converter and distribution are sized correctly. Simultaneous use and the largest starting motor should be reviewed before ordering.
Will it work with CNC equipment?
Phoenix rotary converters are commonly used with CNC equipment. Confirm the machine nameplate, control requirements, voltage, and any transformer needs with the sizing team.
What does installation require?
A qualified electrician should connect the single-phase supply, converter, protection, and three-phase load according to the supplied diagrams and applicable electrical codes.
Ready for three-phase power?
Get the size right before the system ships.
Use the guided sizing tool or speak with a Phoenix engineer to confirm the load, voltage, controls, and complete configuration.
