Fully enclosed, high-resolution miniature linear servo motor features high force-to-size ratio

Moticont has added the SDLM-016-032-01-01-M (Metric) direct-drive linear motor with an integrated encoder and temperature sensor to their SDLM Series of Metric and Imperial dimensioned high precision linear actuators. This motor is the smallest of the series of linear motors featuring zero backlash, zero cogging, high acceleration, high speed, high resolution, and long life. Also known as an electric cylinder, this compact direct-drive linear motor is just 15.9 mm (0.625 in.) in diameter and 31.8 mm (1.25 in.) long. Protected inside the motor housing, a 1.25-micron resolution linear quadrature encoder directly connected to the shaft provides the greatest possible accuracy with zero backlash. Additionally, monitoring the temperature from the internal temperature sensor optimizes highest possible throughput.

This new SDLM-016-032-01-01-M direct-drive motion control linear motor has a stroke length of 6.35 mm (0.250 in.), a continuous force rating of 1.14 N (4.1 oz), peak force of 3.61 N (13.0 oz), and 1.08 N/A (3.9 oz/A) Force Constant. This non-commutated, low-inertia, direct-drive servo motor has quiet long life, plain linear bearings and connections are easily made via a flex cable terminated in a 10-pin female connector.

These miniature linear servo motors are suitable for medical devices (e.g. infusion pumps, prosthetic devices, and surgical robots), automotive and consumer products, aerospace (e.g. aircraft, drones, satellites, and rockets), robotics and industrial automation, and laboratory applications (e.g. microscope stages, pipetting, and sampling).

Direct coupling of the load or stage to non-rotating shaft eliminates backlash and allows for smooth motion. Both ends of the actuator have M1.6X0.35, 0.10 deep threaded mounting holes for easy integration into new and existing applications. Each end of the 2 mm (0.07 in.) diameter shaft has an M2X0.4 male threads with a length of 3.2 mm (0.13 in.)

The SDLM-016-032-01-01-M direct-drive linear actuator is also available with a matching servo controller.
