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. Our 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5mm-diameter output shaft.

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
