VFD Technology for Industrial Applications and Energy Saving

INTRODUCTION

Induction Motors have been the most preferred Prime Mover for Machines and Industrial Equipment cutting across all applications and sectors owing to lower cost, ruggedness, reliability and simplicity of construction; but limitation of variability of speed and requirement of starter have always been associated with them. Historically, costlier and maintenance prone DC Motors, Slip Ring Induction Motors, PIV Gearboxes, Multistage gearboxes and clutches have been used for variability of speed through complex and inefficient schemes.

Although there are options available now but unless the application requires precise position and torque control it does not make sense to go for Permanent Magnet Servomotor based sophisticated Servo Controls. For modest, simpler and cost sensitive applications and for retrofit on existing equipment Variable Frequency Drive (VFDs) remains by far the most effective, elegant and user friendly solution for :

• Achieving variability of speed for flexibility
• Soft start / stop
• Customizing speed-torque characteristics
• Energy saving

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organising a one day training programme on "VFD Technology for Industrial Applications and Energy Saving".
