Our machine shop has also been re-located as part of the business move to Rugby, we anticipate the machines will be operational around mid December. Orders placed which include custom bore sizes and tapped holes will be processed as soon as the machines are spinning again.

This small hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). The motor has four color-coded wires terminated with bare leads. Our 4mm universal mounting hub can be used to mount objects on the stepper motor’s 4mm-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
