This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). It offers a holding torque of 850 g-cm (12 oz-in), and each phase draws 1 A at 3.5 V. This stepper motor’s flat profile (18.6 mm including the shaft) allows it to be used in places where more traditional stepper motors would be too bulky.

Overview

This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution) and a holding torque of 850 g-cm (12 oz-in). Each phase draws 1 A at 3.5 V. The motor has four color-coded wires terminated with bare leads: red and yellow connect to one coil; orange and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver. For more information, see the datasheet (385k pdf).

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
