Product OverviewThe SDLM-038-095-01-01M is a high-force one-inch-stroke direct drive linear servo actuator for demanding positioning and force-control applications. Its housing measures 1.500 in. (38.1 mm) in diameter and 3.750 in. (95.3 mm) long. The actuator provides a 1.000 in. (25.4 mm) stroke, 3.8 lb (16.8 N) of continuous force, and 11.9 lb (52.9 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. Side-load capacity up to 5.4 lb (24.0 N).Integrated Encoder and Temperature SensorThe integrated linear encoder for closed-loop servo operation is protected inside the actuator housing and directly coupled to the output shaft. It provides 1.25 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. The integrated temperature sensor provides thermal feedback that can be used to maximize throughput while keeping the actuator within its operating limits. An integrated HOME sensor supports repeatable system initialization.Key Features• 1.000 in. (25.4 mm) linear stroke• 3.8 lb (16.8 N) continuous force • 11.9 lb (52.9 N) intermittent force at 10% duty cycle • Integrated linear encoder for closed-loop servo operation • Non-rotating 0.250 in. (6.4 mm) shaft with long-life linear bearings • Direct-drive operation with zero mechanical backlash and no cogging • High acceleration, rapid reversal, quiet operation, and long service life • Integrated temperature sensor for thermal monitoring • Integrated HOME sensor • Side-load capacity up to 5.4 lb (24.0 N) ApplicationsMedical and Laboratory: Medical equipment, sampling systems, scanning, and laboratory automation.Industrial Automation: Assembly, workholding, clamping, sorting, packaging, and precision handling. Laser and Optical Systems: Laser machining, drilling, beam steering, filtering, and high-response optical positioning. Mechanical Integration and ControlThreaded mounting holes on a 0.750 in. (19.1 mm) bolt circle are provided at each end of the housing. Threaded shaft ends enable direct, zero-backlash load connection. For closed-loop operation, use a compatible servo controller and current amplifier selected for the required force, speed, duty cycle, load, and motion profile. |
