The new Moticont SDLM-025-070-01-01 direct drive linear motor, also known as an electric cylinder, has a built-in encoder, zero backlash, zero cogging and provides users with high acceleration, high speed, high resolution and long life. This direct drive linear motor features 1.25 µm (0.000049 in.) in of resolution. This compact direct drive linear motor is just 1.00 in. (25.4 mm) in diameter and 2.75 in (69.9 mm) long. Inside the motor housing, the linear optical quadrature encoder is directly connected to the shaft for the greatest possible accuracy.
This direct drive linear motor has a stroke length of 0.500 in. (12.7 mm) and a continuous force rating of 22.2 oz. (5.9 N) and peak force of 67.2 oz (18.7 N). This non-commutated direct drive servo motor features: Quiet long life plain linear bearings, an integrated internal (1.25 micron resolution) quadrature optical encoder with differential outputs and a non-rotating shaft. Applications include: Manufacturing, semiconductor handling, inspection, medical procedure tables, antenna positioning, dampers, door & valve actuators, agricultural equipment and adjustable office furniture.
Direct coupling of the load or stage to the low inertia non-rotating shaft eliminates backlash and allows for high acceleration/deceleration. Both ends of the motor and shaft ends are drilled and tapped for easy integration into new and existing applications. The SDLM-025-070-01-01 Direct Drive Linear Actuator is also available as a complete plug-and-play linear motion system with a matching motion controller.
