VFD Drives
Frequency control devices (Frequency Inverters/VFDs) control the rotation speed and supply voltage of an electric motor. They convert fixed-frequency current into variable frequency, allowing the motor to operate at different speeds.
Why Frequency Converters?
Frequency converters (VFDs) allow companies to precisely control motor speed and energy consumption, which increases system efficiency and reduces energy costs. Their use makes it possible to protect equipment from sudden loads, significantly extending the service life of motors and mechanical parts. Frequency converters also reduce excess energy consumption at startup, improve process control, and increase the overall productivity of your facility.

VFD Drives FAQ
What size VFD do I need for my motor?
The basic rule: the VFD's rated current must exceed the motor's rated current; for heavy-starting machinery (e.g. a fully loaded conveyor) we go one size up. We will do the exact selection for you free of charge.
Will a VFD work with an old motor?
In most cases yes — standard asynchronous motors work well with a VFD. On older motors we check the insulation condition and add a du/dt or sine filter where needed.
How much does a VFD actually save?
On variable-load equipment (fans, pumps, compressors) typically 20-35%, with a payback of 6-18 months. Calculate your exact figure with our free calculator or the motor starting simulator.
Do you also handle installation and commissioning?
Yes — delivery, installation, parameter setup and ongoing service in one place. We are an authorized Danfoss partner.
