TMK Torque Motors

The TMK torque motor range is a unique design redefining the working range of torque motors in the industry. The advanced electromagnetic design of TMK motors allows them to reach speed levels that were totally unsuspected for torque motors. The TMK maximum speed range can reach 8 times the speed of similar size conventional torque motors. In addition, the continuous and peak torque is larger than similar size torque motors. As such, TMK is a unique revolutionary design that drastically changes the definition of “high speed” in the torque motor world.
