Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 42x48mm, 4V, 1200mA

This hybrid stepping motor can be used as a unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps/revolution). Each phase draws 1200 mA at 4 V, allowing for a holding torque of 3.17 kg-cm (44 oz-in).

Note: As of July 16, 2012, this stepper motor has a D-shaft in place of the previously cylindrical shaft. The shaft diameter is still 5 mm, but now a section of the cylinder has been flattened by 0.5 mm. Adapters that worked with the previous shaft should work fine with the new shaft, and the flattened section lets the new shaft work better with set screws.

Overview

This hybrid stepping motor can be used as a unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps/revolution). Each phase draws 1200 mA at 4 V, allowing for a holding torque of 3.17 kg-cm (44 oz-in). The motor has six color-coded wires terminated with bare leads. Our 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5mm-diameter output shaft.

Specifications

  • Size: 42.3 mm square x 48 mm, not including the shaft (NEMA 17)
  • Weight: 350 g (13 oz)
  • Shaft diameter: 5 mm “D”
  • Steps per revolution: 200
  • Current rating: 1200 mA per coil
  • Voltage rating: 4 V
  • Resistance: 3.3 Ohm per coil
  • Holding torque: 3.17 kg-cm (44 oz-in)
  • Inductance: 2.8 mH per coil
  • Lead length: 12 in

Connections

6-lead, unipolar/bipolar stepper motor wires are terminated with bare leads.

This stepper motor can be controlled by unipolar or 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). We recommend using this as a bipolar stepper motor if you have a bipolar driver.

Dimensions

The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 48 mm. The output shaft has a length of 24 mm and a diameter of 5 mm. Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 mm.

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
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives
