The 28STLB33D10 is a ball screw linear hybrid stepper motor with a 20 mm length and 1.8° step angle, designed for precise linear motion applications. It features a ball screw mechanism providing 0.01 mm linear travel per step and 2 mm per revolution, with a minimum holding force of 183.8 N at rated current. The motor operates with a rated phase current of 1 A (2-phase ON) or 1.41 A (1-phase ON), and has a coil resistance of 2.1 Ω and inductance of 1.55 mH. It delivers a stroke length of 80 mm, a step accuracy of ±1 step, and 200 steps per revolution. The unit uses ball bearings, has a weight of 120 g, and includes four AWG26 leadwires. It operates within -20 to +50 °C ambient temperature with a max coil temperature of 130 °C (Class B insulation).
28STLB33 - Ball screw Linear Hybrid Stepper Motor
28STLB33
The 28STLB33 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.
