Standing in front of a CNC spindle or workshop motor that expects three-phase power when your shop only has single phase? That's the classic motor-control puzzle. A variable frequency drive can untangle it by taking your 220V supply and outputting adjustable three-phase speed, but the drive's duty rating matters as much as its horsepower.
1 To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD
This drive is built for 220V class input and accepts either 1-phase or 3-phase power, then outputs 3-phase at 208-240VAC. The input frequency range is 48-63Hz, and the output frequency is adjustable from 0 to 3200Hz. SPWM control mode handles the switching, and the listed maximum current is 20A per phase. The main reason to choose it is the phase flexibility; the limitation is the light-load model rating, so it's not designed for heavy industrial starting torque.
Quick verdict
At USD 130.11, this 7.5KW 10HP VFD gives you single-to-three-phase conversion and variable output frequency in one unit. It suits light CNC spindles and workshop motors that need speed control without extra phase-conversion hardware. Keep the load modest.
Who it suits
This drive suits CNC spindles and other light workshop motors where starting torque stays moderate and running current stays within the 20A per-phase maximum. It's also a straightforward pick for anyone adding VFD speed control to a light motor.
Meaningful trade-offs
The light-load model rating is the main trade-off. The 7.5KW/10HP label can look more substantial than the actual duty capacity, so avoid high-inertia loads or frequent hard starts. Also, because the output voltage is analogous to the input voltage, a low line voltage will be reflected at the output. Operating temperature is -10°C to 40°C, humidity up to 95% without dew, and vibration below 0.5G.
Bottom line
If you need a VFD to add variable speed to a light CNC or motor-control application, this 7.5KW 10HP unit is a practical choice. The 0-3200Hz output range is the standout spec for spindle work, and the 1-or-3-phase input adds wiring flexibility. Respect its duty rating and you have a useful motor-control tool.
