110 kW Variable Frequency Drives — Applications and Selection Guide

110 kW variable frequency drives (VFDs) are mid-range industrial drives designed to control 3×380 V asynchronous motors with smooth start, speed regulation, and overload protection. All models in the VFD catalog at chastotnik.ua operate on a three-phase 380 V supply and deliver output currents ranging from 165 A to 253 A depending on the series.

Typical Applications for 110 kW VFDs

Drives of this power class are widely used across industrial sectors:

  • Pump stations and water supply systems — pressure stabilisation, elimination of water hammer, energy savings of 30–40% vs. direct-on-line starting.
  • Ventilation and HVAC systems — large building fans, industrial exhaust systems, cooling units.
  • Compressors and crushers — loaded soft-start, controlled deceleration, motor overload protection.
  • Conveyor and material-handling equipment — grain terminals, construction machinery, crane drives.
  • Woodworking and metalworking machinery — milling machines, rolling mills, centrifuges.

How to Choose a 110 kW VFD

When selecting a 110 kW drive, consider the following parameters:

  • Load type — constant torque (G-type, pumps, fans) or variable torque (P-type, hoists, conveyors). Most models on this page carry a G/P designation, e.g. AC310-T3-110G/132P means 110 kW constant torque or 132 kW variable torque.
  • Built-in EMC filter — required for industrial environments with sensitive electronics. Models with built-in filter: INVT GD20, Delta VFD-CP2000, ABB ACS880, Schneider ATV610.
  • Built-in brake chopper — necessary for cranes, hoists, and machine tools with regenerative braking.
  • Enclosure rating (IP) — IP20 for cabinet-mounted installations, IP21/54 for harsher environments. ABB ACS880 and ACQ80 come with IP21 as standard.

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.
