The Pololu Stepper Motor: Bipolar, 200 Steps/Rev, 20×42mm, 4.3V, 0.8 A/Phase is a compact NEMA 8-size hybrid bipolar stepping motor designed for applications requiring precise position control. It features a 1.8° step angle, translating to 200 steps per revolution, and operates with a current draw of 800 mA per phase at a voltage of 4.3 V. This configuration provides a holding torque of 300 g-cm, making it suitable for various precision-driven tasks.
Weighing 80 grams, this motor is among the smaller options available, yet it maintains robust performance. The motor is equipped with four color-coded wires terminated with bare leads, facilitating easy connection to control systems. It is compatible with bipolar stepper motor drivers and can be efficiently managed using Tic Stepper Motor Controllers, which offer multiple interface options and USB configurability.
The motor's 4 mm-diameter output shaft is supported by two ball bearings, ensuring smooth operation and durability. It is ideal for use in printers, CNC machines, 3D printers, laser cutters, pick and place machines, linear actuators, and hard drives, where precise control is essential without the need for complex feedback systems.
