Choosing a variable frequency drive usually comes down to one question: can it run your motor without making you pay for capacity you don't need? In the VFDs, soft starters, and motor controls space, the single-to-three-phase conversion is where most shoppers pause. You have a 220V single-phase supply, but your motor expects three-phase power, and the drive has to bridge that gap cleanly. This guide compares four 220V VFDs listed for that job, from a compact single-phase input drive to 7.5KW/10HP units, and shows which one makes sense for common shop loads like CNC spindles, compressors, pumps, and conveyors.
Quick Take
The four drives split into two power tiers. Three are 7.5KW/10HP units using SPWM control, and the fourth is a 750W unit. The listed prices run from USD 32.99 to USD 160.90, so the real decision is choosing the power tier that matches your motor.
Listed Price Comparison
| Product | Listed Price | Price Bar | Distinguishing Detail |
|---|---|---|---|
| 7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD | USD 160.90 | Model GEGS-753, input 1 or 3 phase | |
| 7.5KW 10HP 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD | USD 158.90 | Dimension 38 x 29 x 29 cm | |
| 10HP 7.5KW 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD | USD 158.40 | Title leads with 10HP | |
| Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD | USD 32.99 | Rated current 3.41A, max input current 3.86A |
The price bars show that the three 10HP units cluster near the top of the range, while the 1HP unit sits far below them. If you need 10HP output, the decision is among the top three; if you only need 1HP, the compact drive is the one to look at.
Decision Matrix
| Use Case | Recommended Unit | Why It Fits |
|---|---|---|
| 1HP motor for a light shop task | Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD | The only 1HP drive in the group |
| Full 10HP constant-torque load | 7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD | 7.5KW output with a listed model and input specs |
| 10HP load where a CE statement matters | 7.5KW 10HP 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD or 10HP 7.5KW 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD | Both listings include CE in the attributes |
Product Notes
7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD
This is the 10HP drive to start with if you want a model number in the listing. The attributes list GEGS-753, a 220V input voltage, 1 or 3 phase input, and humidity tolerance up to 95% RH without dew. The input phase detail helps anchor it as a single-to-three-phase converter, and the SPWM control mode is consistent with the rest of the 10HP group. The tradeoff is the description, which mixes in customer feedback and a "Need Help" note, so the cleanest spec information is in the title and attributes.
7.5KW 10HP 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD
If you want the connection method spelled out, this listing's description is helpful. It explains that the input is 220VAC 1 or 3 phase, single-phase input goes to the R and S terminals, and the output is three-phase 220V. The attributes add a CE certificate and a dimension of 38 x 29 x 29 cm. The limitation is that terminal wiring is part of the job, so you need to be comfortable making those connections. If you prefer a listing with more hookup direction, this one gives you that guidance.
10HP 7.5KW 220V Single To 3 Phase Variable Frequency Drive Inverter CNC VFD VSD
This listing puts the 10HP capacity first in the title, which makes the power rating easy to spot. The attributes list the same CE certificate and 38 x 29 x 29 cm dimension as the sibling unit. The concrete limitation is the description, which spends most of its space on customer feedback and a "Why Choose Us" pitch rather than technical details. If you like the 10HP-first title and want the CE statement in the attributes, this is a straightforward pick.
Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD
This is the only 1HP drive in the lineup, and it fits when your motor load is light. The attributes list a 0.75 KW power rating and a model of FOR T13-750W-H, and the listing includes an attention note that 110V input works only with 110V three-phase motors. The limitation is the power ceiling: it's a 750W unit, so it won't drive the 10HP motors the other three are designed for. For a small spindle or a light-duty pump, it's the appropriate size, not an underpowered afterthought.
Final Recommendation by Use Case
Start with the power class you actually need. For a light single-phase-to-three-phase job, choose the Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD. For a larger motor, the 7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD is the primary pick, with the other two 7.5KW/10HP listings as close alternatives.
