New, patent-pending, SDLM-051 direct drive linear motors with built-in encoder from MotiCont eliminate backlash and provide users with high acceleration, high speed, high resolution, and long life. Available in several off-the-shelf models, these direct drive linear motors feature resolutions of 5.2 µm (0.000206 in.), 1.25 µm (0.000049 in), and sub micron resolution. Compact, only 2 in. (50.8 mm) in diameter and 3.75 in (95.3 mm) long, and with the linear optical quadrature encoder inside directly connected to the shaft for the greatest possible accuracy, these motors can be easily integrated into new and existing applications using threaded features on the front and rear faces of the motor, as well as each end of the shaft.
