Phoenix Phase Converters build industrial rotary phase converters from 2 HP to 200 HP β converting single-phase power to true three-phase for CNC machines, pumps, compressors, and any industrial equipment. Select your HP and voltage above to see pricing, then add to cart or call us for sizing help.
π How to Choose Your Phase Converter
Use the dropdown above to select your HP size and voltage. Not sure? Here's how to pick:
β‘ Quick Sizing Guide
Step 1: Find the HP rating on your equipment's motor nameplate.
Step 2: If running multiple machines at once, add up the HP.
Step 3: Pick a converter that matches or exceeds your total HP.
Step 4: Choose 230V or 460V based on your equipment voltage.
| Your Equipment HP | Standard Model | Dual Zone Model | Best For |
|---|---|---|---|
| Up to 5 HP | 5 HP | 5/10 HP | Small machines, pumps |
| 5β10 HP | 10 HP | 10/20 HP | Lathes, mills, compressors |
| 10β20 HP | 20 HP | 20/40 HP | CNC machines, larger tools |
| 20β30 HP | 30 HP | 30/60 HP | Machine shops, farms |
| 30β50 HP | 50 HP | 50/100 HP | Multiple machines, heavy loads |
| 50β75 HP | 75 HP | 60/120 HP | Pumps, industrial facilities |
| 75β100 HP | 100 HP | 100/200 HP | Large operations, multiple motors |
Rule of thumb: When in doubt, go one size up. Oversizing never hurts β undersizing does. For fan loads, multiply HP by 3Γ for inrush.
π Standard vs. Dual Zone
β‘ Standard (Single Motor)
One idler motor provides continuous three-phase power. Simple, reliable, cost-effective.
- Sizes: 2 HP β 100 HP
- Best for: single machine or small shops
- Lower cost entry point
π₯ Dual Zone (Auto-Zoned)
Two idler motors with automatic zoning. Starts loads independently, halves inrush current.
- Sizes: 5/10 HP β 100/200 HP
- Best for: multiple machines, heavy starts
- 2Γ the starting power, runs more efficiently
π 230V vs. 460V Output
230V Three-Phase
Most common. Converts 230V single-phase to 230V three-phase.
- Standard for most US shop equipment
- No transformer needed
- Lower cost, simpler installation
460V Three-Phase
Includes a built-in step-up transformer. Converts 230V single-phase to 460V three-phase.
- For 460V/480V equipment
- Transformer package included
- Common for larger industrial motors
