Choosing a variable frequency drive (VFD) for a three-phase motor means matching both power rating and input voltage to the motor you have. In this group of four single-to-three-phase 220V VFD listings, prices run from USD 32.99 to USD 160.90, and capacities run from 750W/1HP to 7.5KW/10HP. That range matters: the right drive is the one that is rated high enough for the motor and, at the same time, fed from the correct input.
Quick take
The cheapest listing in this set is the 750W 1HP drive, the mid-priced option is Uimoso's 3KW 4HP drive, and the two top-capacity choices are both 7.5KW/10HP drives. The 10HP pair is close on paper, so the visible differences come down to a listed dimension on one and a listed model number on the other.
Listed-price comparison
| Drive | Listed price | Price bar |
|---|---|---|
| Uimoso 3KW 4HP 220V VFD | USD 92.99 | |
| 750W 1HP 220V VFD | USD 32.99 | |
| 7.5KW 10HP 220V Single To 3 Phase VFD | USD 158.90 | |
| 7.5KW 10HP 220V VFD Single To 3 Phase CNC | USD 160.90 |
Decision matrix
| Drive | Consider this if | Keep in mind |
|---|---|---|
| Uimoso 3KW 4HP 220V VFD | You need a 4HP-capable drive with 1- or 3-phase 220V input | Power ceiling is 4HP |
| 750W 1HP 220V VFD | You have a 0.75KW/1HP motor and want a single-phase 220V input | Not for larger motors |
| 7.5KW 10HP 220V Single To 3 Phase VFD | You need 10HP and want a listed enclosure dimension | Other 10HP listing has model number instead |
| 7.5KW 10HP 220V VFD Single To 3 Phase CNC | You need 10HP and want model GEGS-753 | No dimension listed in attributes |
Product notes
Uimoso 3KW 4HP 220V VFD
This is the mid-power drive in the lineup, listed with a 3KW/4HP rating and an input that can be 1- or 3-phase 220V. The description covers constant-torque loads such as hard-starting air compressors and HVAC units, plus variable-torque pumps and fans, and the control mode is Sine wave PWM/SVPWM. The listed input current is 0-14A, and the model number is H100-3S2-1B. The limitation is the 4HP ceiling: if you are trying to run a 10HP motor, this listing is below the stated power range. It gives you a real middle step between the 1HP and 10HP drives, but not a path to 10HP.
750W 1HP 220V VFD
At the low-power end, this listing is rated for 0.75KW/1HP and specifies single-phase AC 220V input with 3-phase AC 220V output. The model is FOR T13-750W-H, and the maximum input current is 3.86A. It is a straightforward match for a small three-phase motor that needs VFD speed control, but the power rating is the built-in boundary: 750W is not enough for 4HP or 10HP motors. The listing also includes an attention note that if the input is 110V, the output is compatible only with 110V three-phase motors, so use the 220V input path if you need the 220V output described in the title.
7.5KW 10HP 220V Single To 3 Phase VFD
This top-capacity listing from zb-equipment is for 7.5KW/10HP motors. The attributes list a dimension of 38 x 29 x 29 cm, which is the only listing in this group to provide physical dimensions. The description says the 220V input can be 1- or 3-phase and the output is 3-phase, so it is aimed at single-to-three phase conversion at high power. The limitation is that the other 7.5KW drive in the lineup has the same power class and SPWM control mode, so you are choosing between very close siblings. If you need to plan around enclosure space, this one gives you the measurement; if you need a model number, the other 7.5KW listing provides that.
7.5KW 10HP 220V VFD Single To 3 Phase CNC
This is the other 7.5KW/10HP drive in the lineup, and the attributes identify model GEGS-753. The 220V input is listed as 1- or 3-phase, and the description frames it for single-to-three phase use, covering compressor, CNC, and spindle-motor use cases. A limitation worth noting is that no dimension appears in its attributes, so if you are measuring a cabinet, the sibling 7.5KW listing is the one with the 38 x 29 x 29 cm dimension. The model number is the concrete extra piece of information here, which can be handy for reference.
Final recommendation by use case
- Small 1HP motors: take the 750W drive. It carries the lowest listed price and matches the 0.75KW/1HP rating.
- 3KW/4HP constant-torque or variable-torque loads: the Uimoso drive accepts 1- or 3-phase 220V and lists the 4HP capacity.
- 7.5KW/10HP machines: if you need a physical dimension for an enclosure, the Single To 3 Phase VFD listing provides one; if you want a model number to reference, the other 7.5KW listing identifies model GEGS-753.
