TRM Series Frameless Torque-Motors

MDS torque motor series are engineered to deliver the high-performance, high efficiency direct drive torque motors that today’s applications demand. There exist 3 main torque motor series offered: Frameless and framed torque motor with and without liquid cooling. Optional digital Hall effect sensors are prealigned and installed with added axial rotor length to achieve accurate control. Choice of insulation allows operation from 24V up to 560V peak line input voltage. Detailed motor datasheets and variety of motor options and configurations provide the best selection for your needs.

For customized motor selections or new custom motor specifications, contact MDS Motor to help us understand exactly what you need and how we can further optimize any MDS torque motor series. MDS Motor is expert in providing optimized custom solutions for your applications with utilizing different materials, special winding structures, tailored mounting features, height and diameter adjustments and etc.

TRM series frameless torque motor product family includes two different sub series according to DC bus voltage levels. Low voltage (24/48V) motors are named as TML series torque motor. High voltage (310/560V) motors are named as TMH series torque motor.
