1207-POLOLU Stepper Motor: Bipolar, 200 Steps/Rev, 35×26mm, 7.4V, 0.28 A/Phase

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 650 g-cm (9 oz-in).

This 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 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.

 

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.

Specifications

  • Size: 35 mm square × 26 mm, not including the shaft (NEMA 14)
  • Weight: 130 g (4.5 oz)
  • Shaft diameter: 5 mm “D”
  • Steps per revolution: 200
  • Current rating: 280 mA per coil
  • Voltage rating: 7.4 V
  • Resistance: 26 Ω per coil
  • Holding torque: 650 g-cm (9 oz-in)

More specifications are available in the datasheet (37k pdf).

Dimensions

The 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.

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
