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).

 

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.

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