VARIABLE FREEQUENCY DRIVES

variable1Variable Frequency Drives (VFDs) – a type of adjustable speed drives used in electro-mechanical drive systems to control AC motor speed and torque by the varying motor input frequency and voltage – are used in applications extending from small appliances to the largest of mine mill drives and compressors. One of the most important advantages of the VFD installations is substantial energy efficiency improvement opportunities. Another benefit of the VFDs is reduced wear and tear on the motors. These drives also provide more precise levels of control of applications.

For more than 20 years, VFDs have been successfully installed around the world on fan and pump motors in an extensive range of variable load applications. The high cost of VFDs in the past made their application uneconomical. The introduction of cost-effective VFDs has dramatically changed this situation. VFDs have become more commonly used in industrial applications due to their ability to save owners’ money and improve product quality. Energy savings from the installation of VFDs vary from 35% to 50% over the conventional constant-speed applications, thereby resulting in a return on investment of six months to two years.

Elensol offers a wide portfolio of comprehensive VFD solutions from the innovative world leaders in the business, who are our partners. Our VFD solutions are fully integrated with the expertise in installation, testing, commissioning, training, fault management, preventive maintenance, and post-sale service and support. The list of VFDs available from us includes drives specifically designed for individual applications in HVAC, pump control and other industrial systems. Ultra-efficient drives, which provide higher efficiency for many applications, are also in our range of VFDs. Another important solution in our selection of drives is Clean Power Drives, which substantially brings down line harmonics at the line input terminals, thereby bringing in some better sinusoidal waveforms at the input.
