Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

Description

This NEMA 14-size hybrid bipolar stepping motor has a 1.8?? step angle (200 steps/revolution). Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650g-cm (9 oz-in).

The motor has four colour-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 5mm universal mounting hub can be used to mount objects on the stepper motor??s 5 mm-diameter output shaft, and our NEMA 14 aluminium bracket offers a variety of options for mounting this stepper motor in your project.
