Stepper Motor: Bipolar 200 Steps/Rev 35x26mm 7.4V 280mA - NEMA 14 [229]

This hybrid bipolar stepping motor has a 1.8� step angle(200�steps/revolution). Each phase draws 280�mA at7.4�V allowing for a holding torque of 650�g-cm(9�oz-in). The motor has four color-coded wires terminated withbare leads. Our 5mmuniversal mounting hub can be used to mount objects on the steppermotor�s 5mm-diameter output shaft.

Stepper Motor Applications

Stepper motors are generally used in a variety of applications whereprecise position control is desirable and the cost or complexity of afeedback control system is unwarranted. Here are a few applicationswhere stepper motors are often found:

• Printers
• CNC machines
• 3D printer/prototyping machines
• Laser cutters
• Pick and place machines
• Linear actuators
• Hard drives
