When you're assembling a motor-control setup, the most important fork in the road is usually not whether you need speed control, but whether you start with a new general-purpose inverter or a used industrial drive. The 7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD and the Vortek SP1406 Unidrive SP Variable Frequency Drive sit on opposite sides of that decision.
Quick Verdict
For most shop applications, the 7.5KW 10HP VFD is the straightforward pick because it uses SPWM control and is the new option in this pairing. For a project that needs the SP1406 model specifically, the used Vortek drive is the more targeted choice.
Comparison Table
| Feature | 7.5KW 10HP VFD | Vortek SP1406 Unidrive SP |
|---|---|---|
| Price | USD 158.90 | USD 359.97 |
| Brand | zb-equipment | Control Techniques |
| Model | GEGS-753 | Unidrive SP (SP1406) |
Where Each Product Wins
- The 7.5KW 10HP VFD wins on new-condition buying and single-to-three-phase input flexibility. It is a solid match for a shop that only has single-phase service and needs to drive a three-phase load.
- The Vortek SP1406 wins on the Unidrive SP platform and model-level specificity. If you have a system that already uses Unidrive SP drives, the SP1406 model number is a direct fit.
Product Notes
7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD

On the new drive side, this unit makes its case with single-to-three-phase input capability. That is a significant convenience for shops that have 220V single-phase service but need to run a three-phase motor. The listing also identifies SPWM control, a 48-63 Hz input frequency range, and the GEGS-753 model number. The drive is listed as new, so you are not inheriting someone else's wear or wiring. The description points to constant-torque loads like air compressors and HVAC units plus variable-torque uses like CNC spindles and grinders. The country of origin is China, which is a practical detail if your project has domestic-content requirements. The main limitation is the 220V input requirement; this drive is built for 220V single- or three-phase input, so higher-voltage services are out of its listed range.
Vortek SP1406 Unidrive SP Variable Frequency Drive

The Vortek SP1406 Unidrive SP takes a different approach. It is a used drive, and the description says it was removed from a working environment, which is useful context for anyone repairing or expanding an existing installation. The Control Techniques Unidrive SP platform and the SP1406 model number give this unit a clear identity in an established industrial product family. The trade-off is the used, as-is nature of the sale; the listing states that only pictured items are included and that the unit is sold as-is. Any connectors, mounting hardware, or auxiliary components you need will have to come from elsewhere. For a control panel that already expects a Unidrive SP, the model-level fit is the reason to pick this drive, and the used status is the condition you accept for that match.
Final Choice by Use Case
If you want a new inverter, plan to run a 220V single-phase feed into a three-phase motor, and want to stay at the lower end of the $158.90-to-$359.97 spread, the 7.5KW 10HP VFD is the more practical starting point. If you are matching an existing drive system, need the SP1406 model specifically, and can accept a used as-is unit with only pictured parts, the Vortek SP1406 is the drive to pick.
