Product OverviewThe SDLM-025-070-01-05 is a 5-micron encoder version of Moticont’s compact 1.000-inch-diameter direct drive linear servo motor. Its housing measures 1.000 in. (25.4 mm) in diameter and 2.750 in. (69.9 mm) long. The actuator provides a 0.500 in. (12.7 mm) stroke, 21.2 oz (5.9 N) of continuous force, and 67.0 oz (18.6 N) of intermittent force at a 10% duty cycle.Performance and ConstructionThe non-commutated direct-drive design eliminates ball screws, gears, belts, and other mechanical transmission components. Direct coupling to the low-inertia output shaft provides zero mechanical backlash, no cogging, high acceleration and deceleration, smooth bidirectional motion, quiet operation, and long service life.Integrated EncoderThe integrated quadrature optical encoder is protected inside the actuator housing and directly coupled to the output shaft. It provides 5 microns resolution for closed-loop position and velocity control. Final system accuracy and repeatability also depend on the controller, mechanical installation, load, structural stiffness, and servo tuning.Key Features• 0.500 in. (12.7 mm) linear stroke• 21.2 oz (5.9 N) continuous force • 67.0 oz (18.6 N) intermittent force at 10% duty cycle • Integrated quadrature optical encoder • Low-inertia non-rotating output shaft with plain linear bearings • Direct-drive operation with zero mechanical backlash and no cogging • High acceleration, rapid reversal, quiet operation, and long service life ApplicationsIndustrial Automation: Pick-and-place, assembly, inspection, sorting, packaging, and material handling.Medical and Semiconductor: Medical equipment, laboratory automation, and semiconductor handling. General Positioning: Antenna positioning, dampers, valve actuators, and other short-stroke servo applications. Mechanical Integration and ControlThe direct-drive construction and threaded shaft ends support simple, backlash-free connection to the load. For closed-loop operation, use a compatible servo controller and current amplifier selected for the required force, speed, duty cycle, load, and motion profile. |
