With a single-phase supply in the shop and a three-phase motor to run, the simplest fix is a variable-frequency drive (VFD). These devices convert single-phase input to three-phase output while giving you speed control, but they are not interchangeable: input phase support, horsepower, control logic, and whether the unit is new or used all change the decision. This guide walks through four drives in the VFD and motor-control space-a used Yaskawa V1000, a compact unit, and two larger-capacity drives-so you can match the right one to your motor and budget.
Quick take
If you want the cheapest point of entry and a specific Yaskawa model, the V1000 is the door opener. If you want a space-saving drive, the compact '1-to-3 phase' VFD is the direct match. If you need the highest capacity in this group, the two findmall drives use SPWM control and accept either single- or three-phase input, with one carrying a wider output-frequency spec and the other covering a broader torque-load range.
Listed-price comparison
The table below shows the absolute listed prices and how the four drives stack up on a simple bar. Use the bars as a price-position gauge, not a final verdict.
| Product | Listed Price | Price Bar |
|---|---|---|
| Yaskawa CIMR-VA2A0001BAA V1000 VFD | $40.00 | |
| 2.2 kW 3 HP 1-to-3 Phase VFD | $65.83 | |
| findmall 7.5 kW VFD (662506) | $119.34 | |
| findmall 7.5 kW VFD (LAW152886) | $130.11 |
Decision matrix
Before the individual write-ups, use these four decision paths:
- If a specific Yaskawa V1000 model and the smallest cash outlay matter more than condition, start with the V1000.
- If you need a drive for a compact layout and a smaller motor, choose the '1-to-3 phase' VFD.
- If your application is a pump, fan, air compressor, or HVAC load and you need the bigger capacity class, the findmall VFD with the lower listed price covers both constant- and variable-torque jobs.
- If you want the same bigger capacity in a light-load model, pick the findmall VFD with the LAW152886 reference.
Drive-by-drive breakdown
Yaskawa CIMR-VA2A0001BAA V1000 VFD
The Yaskawa CIMR-VA2A0001BAA V1000 is the only used drive in the group and the entrance point for buyers who want a specific V1000 without paying new-drive prices. The model number in the title is explicit, so it is easy to reference the series and compare other V1000 configurations. The low end of the price spread makes it a low-friction trial for someone new to VFDs. The limitation is the used condition: it is the only option here that is not new, and that alone is enough to weigh carefully. For a non-critical motor or a first project, this trade-off is acceptable; for critical production, one of the new drives is a cleaner fit.
2.2 kW 3 HP 1-to-3 Phase VFD
The 2.2 kW 3 HP 1-to-3 Phase VFD is the only 3 HP / 2.2 kW option on the list, and its narrow body with independent air duct supports heat dissipation. That makes it a sensible fit when panel space is tight or you want to line drives up side by side. It accepts a 1-phase 220V input, so it is a direct match for a single-phase shop feeding a three-phase 3 HP motor. The limitation is the capacity ceiling: 3 HP is the maximum rating here, so it cannot handle a 7.5 kW / 10 HP motor. If your motor is larger than 3 HP, you need to move up to one of the 7.5 kW drives in the comparison table.
findmall 7.5 kW VFD (662506)
The findmall 7.5 kW VFD with the 662506 reference is the lower-priced member of the two 7.5 kW / 10 HP drives. It is positioned for constant-torque loads such as air compressors and HVAC units, and for variable-torque loads such as pumps and fans. It uses SPWM control and accepts either 1-phase or 3-phase input, making it a flexible phase-conversion tool for a 10 HP motor. The limitation is that its listed price is near the top of the group; if your motor is only 3 HP / 2.2 kW, you would be paying for capacity you do not need. For a 10 HP fan, pump, compressor, or HVAC blower, it delivers the capacity at a lower listed price than the LAW152886 drive.
findmall 7.5 kW VFD (LAW152886)
The findmall 7.5 kW VFD with the LAW152886 reference carries the higher listed price in the pair and the output-frequency spec that reaches 3,200 Hz. It is SPWM-controlled and accepts either 1-phase or 3-phase input, so the supply-side flexibility is the same as the 662506 unit. The limitation is that it is labeled a light-load model. That makes it a better match for lighter duty such as pumps and fans than for heavy constant-torque work. If you want 10 HP capacity and extra frequency headroom, this is the drive to choose. If your application is more demanding, the 662506 drive is the safer fit.
Final recommendation by use case
Finally, match the drive to the project:
- For the smallest cash outlay and a specific Yaskawa V1000 model, choose the CIMR-VA2A0001BAA V1000 if you can accept used condition.
- For a compact layout and a smaller motor, pick the 1-to-3 phase VFD with the narrow-body design.
- For the larger-capacity class, select the findmall drive with the 662506 reference.
- For larger-capacity work, choose the findmall drive with the LAW152886 reference.
