This hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.2 A at 4 V, allowing for a holding torque of 3.2 kg-cm (44 oz-in). The motor has six color-coded wires terminated with bare leads that allow it to be controlled by both unipolar and bipolar stepper motor drivers. When used with a unipolar stepper motor driver, all six leads are used. When used with a bipolar stepper motor driver, the center-tap yellow and white wires can be left disconnected (the red-blue pair gives access to one coil and the black-green pair gives access to the other coil). Pololu recommend using it as a bipolar stepper motor and controlling it with one of Pololu's bipolar stepper motor drivers or one of Pololu's 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 Pololu's free configuration utility.

Pololu's 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and Pololu's NEMA 17 aluminum bracket offers a variety of options for mounting this stepper motor in your project. A similar NEMA17 stepper motor is available with a threaded rod output shaft that converts its rotations into linear motion of the included traveling nut.

Specifications

  • Size: 42.3 mm square × 48 mm, not including the shaft (NEMA 17)
  • Weight: 350 g (13 oz)
  • Shaft diameter: 5 mm “D”
  • Steps per revolution: 200
  • Current rating: 1.2 A per coil
  • Voltage rating: 4 V
  • Resistance: 3.3 O per coil
  • Holding torque: 3.2 kg-cm (44 oz-in)

More specifications are available in the datasheet (189k pdf).

Dimensions

The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 48 mm. The output D-shaft has a 5 mm diameter with a section that is flattened by 0.5 mm. This shaft works with Pololu's 5 mm universal mounting hub.

Stepper Motor Applications

Stepper 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:

  • Printers
  • CNC machines
  • 3D printer/prototyping machines (e.g. RepRap)
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives

Note: This stepper motor is SOYO part number SY42STH47-1206A.
