Available from Heidenhain, Etel’s four series of direct-drive iron-core torque motors are said to be suitable for machine tool applications including machining centers, turn-mill machines, rotary tables, transfer machines and more. More than 100 models are available across the TMK, TMB, TML and TMM torque motor series.
All of the motors feature an anti-cogging design and a compact coil construction to support peak force density in the magnetic gap with minimal torque ripple, the company says. The TMK-series motors are high-speed torque motors designed for demanding applications. The TMB torque motors are equipped with a cage for water cooling, while the TML and TMM are cageless variants of the TMB design for applications where water cooling is not required.
