2.2 kW Variable Frequency Drive — for Pumps, Fans, and Conveyors
A 2.2 kW variable frequency drive is one of the most popular sizes for small and medium industrial mechanisms. Models are available for single-phase 220V (1ph input, 3ph output) and three-phase 380V supply. Used for speed control of pumps, fans, conveyors, mixers, and woodworking machines.
How to Choose a 2.2 kW VFD: Single-Phase or Three-Phase
The choice depends on the available power supply and motor type. Single-phase models (220V input) suit domestic and small production sites. Three-phase (380V) models are for industrial applications with full protection features.
| Model | Series | Supply | Application |
|---|---|---|---|
| Veichi AC10-T3-2R2G-B | AC10 | 3ph 380V | Conveyors, machine tools |
| Veichi AC310-T3-2R2G-B | AC310 | 3ph 380V | Pumps, fans (built-in PID) |
| Veichi AC10-T/S2-2R2G-B-VC | AC10 | 1ph 220V | Domestic pumps, small machines |
| Delta VFD022E43A | VFD-E | 3ph 380V | Universal industrial mechanisms |
| INVT GD20-2R2G-4 | GD20 | 3ph 380V | Conveyors, extruders |
Common Mistakes When Selecting a 2.2 kW VFD
- Selecting by power instead of current — a 2.2 kW motor from different manufacturers may draw 5 to 10A. Always match the VFD to the motor rated current.
- Single-phase VFD on a three-phase supply — single-phase models (220V input) do not work with 380V. Check the supply type.
- No headroom for heavy-duty starts — for conveyors, crushers, and high-inertia loads, choose one size up (3 kW).
- Scalar mode for precision mechanisms — for machines requiring speed accuracy, choose a vector VFD, not scalar.
When You Need Power Headroom
| Mechanism | Recommended VFD Power | Reason |
|---|---|---|
| Pump, fan | 2.2 kW (1:1) | Easy start, constant load |
| Unloaded conveyor | 2.2 kW (1:1) | Standard starting torque |
| Loaded conveyor | 3 kW (+30%) | Increased starting torque |
| Crusher, mixer | 3 kW — 5.5 kW | Heavy start, load inertia |
| Machine with reverse | 3 kW (+30%) | Frequent braking and reverse |
