Industries & Applications

High-Torque Applications

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. Often, they must also maintain constant torque over speed ranges exceeding 200% of rated speed. These high-torque conditions present particular problems to engineers who specify components for manufacturing and process equipment, and it is here where Dynamatic® drives excel.
