Dynamatic® adjustable speed drives deliver high torque over a wide speed range

The range of torque needed to start and operate specific conveyors, presses, and other industrial machines presents a distinct torque-versus-speed profile. For example, a typical torque-speed requirement for a metal-stamping press might be 200% of full motor load for starting, 75% for accelerating, 100% for peak running.

Frequently in high-torque applications, there is a significant difference between the drive’s normal operating torque and occasional torque demands experienced at start-up or when loading changes. These overloads create conditions that favor the use of Eddy Current adjustable speed drives, because these drives have an inherent capability of generating momentary high torque. Engineers should consider them when torque requirements exceed 200% of rated torque. For cooling, these drives have built-in fans that operate at motor speed rather than output-shaft speed. This feature allows the fan to run much faster than rated output speed.

Industrial drives routinely must handle overloads as great as 150-250% of normal running torque. These high-torque conditions present problems to engineers who specify components for manufacturing and process equipment, and it is here where Dynamatic® drives excel.
