Danfoss VLT® and VACON® drives, now one company, offer 68 years of combined experience and 5,000 people specialized in AC drives.
A variable frequency drive (VFD), is a device used to control the speed of an electrical motor in order to:
- enhance process control
- reduce energy usage and generate energy efficiently
- decrease mechanical stress on motor control applications
- optimize the operation of various applications relying on electric motors
Drives can also be utilized to convert energy from natural and renewable resources like the sun, wind or tides, and transmit it to the electrical network or use it for local consumption. In hybrid technologies, variable frequency drives are used to combine conventional energy sources and energy storages to create total energy management solutions
Variable frequency drives are also known by various other names such as adjustable speed drives, adjustable frequency drives, AC drives, variable speed drives, frequency converters, inverters and power converters.
