The 57STLB45D30 is a 57 mm hybrid stepper motor with an integrated ball screw, providing linear motion with 0.01 mm per step and 2 mm per revolution at rated current. It offers a holding force of 900 N when energized and 42.4 N when unenergized, with a 105 mm stroke length and ±1 step linear travel accuracy. The motor operates with 3 A per phase (2-phase ON), 0.95 Ω resistance per phase, and 3 mH inductance per phase. It features ball bearings, Class B insulation, and operates within -20 to +50 °C ambient temperature. The 4-wire lead configuration uses AWG22 wire, and the unit weighs 511 g.
57STLB45 - Ball screw Linear Hybrid Stepper Motor
57STLB45
The 57STLB45 is a 2 phases linear actuator which combines the technologies of hybrid stepper motors with integrated ball screws and nuts for compact and efficient solutions. The ball screw assemblies function with a nut that contains a ball that rolls between their matching helical grooves. Ball screws can apply or withstand high thrust loads with minimum internal friction (>90% efficiency). Ball Screw Linear Actuators are suitable for higher Duty Cycle and Faster thrust loads.
