220 kW Variable Frequency Drives — High-Power Industrial Motor Control

A 220 kW variable frequency drive (VFD) provides smooth speed and torque control for three-phase induction motors in heavy industrial applications. All models listed here operate on a 3x380 V three-phase supply with output current in the range of 399–426 A. Browse the full range on our Variable Frequency Drives page, or use the power filter to find 220 kW units specifically.

Applications of 220 kW VFDs

At this power level, VFDs are typically used in the following industrial systems:

  • High-capacity pumps — water supply stations, irrigation, industrial process pumps. Built-in PID controller maintains constant pressure and eliminates water hammer.
  • Compressors and fans — mine ventilation, industrial HVAC, cooling towers. Vector mode provides precise airflow control under variable load.
  • Conveyors and belt systems — soft start and ramp-down reduce mechanical wear and inrush current spikes.
  • Crushers and mills — constant-torque (CT / G-type) mode handles 150 % overload for 60 seconds.
  • Mixers, extruders, centrifuges — accurate speed regulation even under sudden load changes.

Frequently Asked Questions

What is a variable frequency drive and how does it work?

A VFD is an electronic device that converts AC mains voltage to DC (rectifier stage), then back to AC with adjustable frequency and amplitude (inverter stage). By varying the output frequency from 0 to 600 Hz, it smoothly controls the rotational speed of an AC induction motor from standstill to rated speed and beyond, while limiting starting current to 1.5× rated.

How do I size a VFD for my motor?

The VFD power rating should equal or exceed the motor nameplate power. For pumps and fans (variable torque), select based on the motor rating. For conveyors, cranes, and crushers (constant torque or heavy starting), choose one power step above — for example, for a 4 kW conveyor motor, we recommend a 5.5 kW VFD. Also verify that the motor's rated current does not exceed the VFD's current rating.

Can I run a three-phase 380V motor from a single-phase 220V supply?

Yes, you need a VFD with single-phase 220V input and three-phase 380V output, such as the Veichi AC70E or AC10 T/S2 variant. Power is limited to 2.2–4 kW depending on the series. The VFD not only starts the motor but also provides soft starting, speed control, and overload protection.

What is the difference between scalar and vector control?

Scalar control (V/f) maintains a constant voltage-to-frequency ratio — a simple, reliable method for pumps, fans, and compressors. Vector control (SVC, FOC) calculates motor current and flux vectors in real time, delivering 150–200% rated torque at low frequencies. Vector control is essential for conveyors, elevators, extruders, cranes, and CNC machine tools.

Why do I need an EMC filter in a VFD?

An EMC (electromagnetic compatibility) filter reduces high-frequency interference that the VFD generates in the power supply and airwaves. It is mandatory for facilities with sensitive equipment (medical, laboratories, server rooms), residential buildings, and when the cable between VFD and motor exceeds 25 m. The Veichi AC10, Delta VFD-E, and INVT GD20 models include a built-in Class C3 EMC filter.

How much energy does a VFD save?

On pumps and fans, savings range from 20% to 60% depending on the load profile. Power is proportional to the cube of speed (P∝n³): reducing speed by 20% halves energy consumption. If equipment typically operates at 70–80% of rated speed, average savings are approximately 40%. Payback period for a VFD on a pumping station is 6 to 18 months.
