The 57STLB45D30 is a 57 mm diameter hybrid stepper motor with an integrated ball screw, designed for linear motion applications. It has a 1.8° step angle, 200 steps per revolution, and a 105 mm stroke length. The motor delivers a holding force of 900 N at rated current with a linear travel accuracy of ±1 step. Electrical characteristics include a phase resistance of 0.95 Ω, phase inductance of 3 mH, and a rated current of 3 A per phase (2-phase ON). It operates within an ambient temperature range of -20 to +50 °C and features a maximum coil temperature of 130 °C (Class B insulation). The motor uses ball bearings, has four AWG22 leadwires, weighs 511 g, and meets a dielectric withstanding voltage of 500 VAC for one minute.
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.
