Ring torque motors raise machine performance

Schaumburg, IL —Three new torque motor models increase accuracy and velocity stability, provide very high bandwidth, and reduce wear and maintenance in machine tools. TMA-0175, TMA-0291, and TMA-0450 Series (corresponding to the motor diameter) fill the moderate to high-torque range of 20 to over 1,000 Nm (14.

Schaumburg, IL – Three new torque motor models increase accuracy and velocity stability, provide very high bandwidth, and reduce wear and maintenance in machine tools. TMA-0175, TMA-0291, and TMA-0450 Series (corresponding to the motor diameter) fill the moderate to high-torque range of 20 to over 1,000 Nm (14.75-737 lb-ft). These direct-drive, brushless, ring torque motors simplify machine design and reduce cost by eliminating worm-gear drives or other transmission elements. TMA Series torque motors include liquid cooling provision to eliminate heat transfer to the machine structure. They work with a wide range of popular CNCs and servo controllers.
