Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650 g-cm (9 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 or one of our Tic Stepper Motor Controllers. In particular, the Tics make control easy because they support six different interfaces (USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder) and are configurable over USB with our free configuration utility. 5mm Pololu universal aluminum mounting hub on a stepper motor with a 5mm-diameter output shaft. NEMA 14 stepper motor (item #1207) mounted with a Pololu stamped aluminum L-bracket for NEMA 14 stepper motors. Bipolar stepper motor wires are terminated with bare leads.Bipolar stepper motor wiring diagram.Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and our NEMA 14 aluminum bracket offers a variety of options for mounting this stepper motor in your project.More specifications are available in the datasheet (37k pdf).DimensionsThe following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 26 mm. The output D-shaft has a length of 21 mm and a 5 mm diameter with a section that is flattened by 0.5 mm. This shaft works with our 5 mm universal mounting hub.The inside of a bipolar stepper motor (SOYO NEMA 14-size).Stepper Motor ApplicationsStepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found:Pololu’s assortment of stepper motors.Note: This stepper motor is SOYO part number SY35ST26-0284A.
