The 20STLN28D05 is a 20 mm diameter non-captive linear hybrid stepper motor with a 1.8° step angle and a maximum holding force of 45 N at rated current. It features a ball bearing, 45 mm stroke length, and 200 steps per revolution. The motor operates with a rated current of 0.5 A per phase (2-phase on) and has a resistance of 5.1 Ω per phase with an inductance of 1.6 mH. Linear travel per step is 0.003048 mm for the AA variant. It has a 4-wire bipolar configuration, operates from -20 to +50 °C, and has a maximum coil temperature of 130 °C (Class B). Weight is 43 g. Linear travel accuracy is ±1 step.
20STLN28 - Non-Captive Linear Hybrid Stepper Motor
20STLN28
The 20STLN28 is a 2 phases linear hybrid stepper motor. With only 20mm width, it's miniature size and high linear force makes it an ideal solution for application with space constraint such as small precision instruments. The non-captive version is ideal for applications requiring precise linear movement, customizable travel distances, and the flexibility to adjust the actuator's function based on the fixed element, be it the motor or the leadscrew. It provides high-performance, precision, and customization, making it an excellent choice for applications ranging from automation to robotics, where specific movement patterns and distances are critical.
