Torque Motors

Innovative Motion Control ABOUT ETEL TORQUE MOTORS Over the last 30 years, direct drive torque motors have provided significant performance improvements in numerous applications covering a wide range of high-tech industries. Today, direct drive technology is recognized as a leading solution towards meeting the requirements of high productivity, improved accuracy, and increased dynamics of modern machinery. What is a torque motor? Direct drive essentially means the load and motor are directly connected without any intermediate gear train. Significant improvement to stiffness and a more...

Innovative Motion Control WHY ADOPT TORQUE MOTORS? Reduced cost of ownership Technology expertise Direct drive Direct coupling of the payload to the rotor eliminates the need for mechanical transmission elements such as gearboxes, timing belts, speed reducers and worm gear drives. And unlike brushed rotary motors, there is no contact between rotor and stator; therefore there is no mechanical wear resulting in excellent reliability and long lifetimes. Fewer mechanical parts also minimizes maintenance and reduces the system cost. The direct drive technology intrinsic to a torque motor system...
