Shopping for a variable frequency drive (VFD) for a 3-phase motor means matching the drive's power and current ratings to your motor, and checking the input power you have available. The four drives in this guide convert a 220V-class supply to three-phase output, but they span from a compact 3HP unit to 10HP models with different current limits. Listed prices run from USD 79.90 to USD 198.90.
Quick Take
For a 3HP motor, the VEVOR 2.2KW drive is the lowest-priced option. If you need 4HP and want the flexibility of 1-phase or 3-phase input, the Uimoso 3KW fits that gap. For full 10HP output, the VEVOR 7.5KW offers a 34A current rating, while the marddpair 7.5KW lists a 40A max per phase at a lower listed price.

| 3HP motor | VEVOR 2.2KW | Lowest listed price and a 10A rating matched to 3HP. |
| 4HP motor | Uimoso 3KW | 0-14A input current range and 4HP output. |
| 10HP motor with high current | VEVOR 7.5KW | 34A current rating and 10HP output. |
| 10HP motor at a lower price | marddpair 7.5KW | 40A max per phase and a listed price below the VEVOR 10HP. |
Product Notes
VEVOR VFD 2.2KW 10A 3HP Variable Frequency Drive for 3-Phase Motor Speed Control
The VEVOR 2.2KW is the lowest-priced drive in this guide at USD 79.90, and its 10A rating lines up with a 3HP motor. It lists AC 220-240V single-phase input and 50/60Hz input frequency. Soft start/stop and a programming panel for adjusting speed parameters are listed features. One limitation is the 3HP ceiling: it works for small motors but not larger loads. If you may need to connect from a 3-phase supply, the Uimoso and marddpair drives list that option. For a straightforward 3HP single-phase-to-3-phase setup, this VEVOR drive keeps the initial cost low.
VEVOR 7.5KW 10HP Variable Frequency Drive VFD for 3-Phase Motor Speed Control
At USD 198.90, the VEVOR 7.5KW is the highest-priced drive in this comparison. It pairs a 10HP rating with a 34A current rating, and the input voltage is listed as AC 220-240V single phase. The 10HP output matches the marddpair drive, but this VEVOR model lists a specific model number (AT1-7500X), which can help with reference. The main limitation is the price: it carries the highest listed price among these four drives, so if a 4HP unit would cover your motor, you could spend less elsewhere.
Uimoso 3KW 4HP 220V Variable Frequency Drive Inverter Converter 1 To 3 Phase VFD
The Uimoso 3KW is priced at USD 92.99 and targets 4HP motors with a 0-14A input current range. It lists an input phase of 1 or 3 phase and an input voltage of 220V, so it works with a single-phase or a 3-phase supply. The input frequency is 50/60Hz, and the model number is H100-3S2-1B. Because it maxes out at 4HP, it won't handle 10HP motors, which makes it best suited to medium-load equipment. That horsepower ceiling is the main limitation.
1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD
This marddpair-branded drive comes in at USD 119.39, offering 10HP capacity with 1 or 3 phase input and a 40A max per phase rating. The 220V input and 48-63Hz input frequency cover typical utility power. Compared with the VEVOR 7.5KW, this unit lists a lower price and a higher per-phase current. The gtin is listed as "Does not apply," so a standard product identifier is not provided. That is the main limitation to keep in mind, though the 10HP output and input flexibility are the key highlights.
Final Recommendation
If you need a 3HP drive, the VEVOR 2.2KW offers the lowest listed price. For a 4HP motor, the Uimoso 3KW covers that capacity. When you need 10HP, the VEVOR 7.5KW provides a 34A current rating, while the marddpair 7.5KW delivers 10HP at a lower listed price than the VEVOR 7.5KW.
