If the AC motor is the lifeblood of industry then the variable speed drive (VSD) is the artery through which that lifeblood flows, controlling every aspect of motor performance to increase efficiency, lift productivity, deliver safety and protect against premature mechanical failure.
Often referred to as the electrical interface into the mechanical world, variable speed drive design has evolved over three decades to become a cornerstone of industrial automation and integrated machine safety.
In its simplest form, the variable speed drive is now a commodity item, providing industrial end-users with simple plug-and-play drive solutions that require minimal user input to achieve basic motor control functionality across core operating parameters – speed, torque and start-up.
