Bell-Everman is announcing the availability of the innovative ServoBelt linear drive, which provides belt-drive economy with screw-drive servo responsiveness, accuracy and repeatability, and linear motor-drive speed.
At the heart of the technology is a static bonded lower belt that meshes with the upper dynamic belt so that the active belting under tension is only a few inches long. Servo tuning can have much higher gains than conventional belts, because stiffness is high and does not change throughout the travel.
