Pololu NEMA-8 Schrittmotor - Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase
This small NEMA 8-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is one of the smallest stepper motors we carry.
This small hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
Our 4 mm universal mounting hub can be used to mount objects on the stepper motor’s 4 mm-diameter output shaft.
