Bipolar stepper motor wires are terminated with bare leads.

Sanyo bipolar stepper motor wiring diagram.


This NEMA 17-size pancake bipolar stepping motor from Sanyo features an integrated high-resolution (1000 P/R) quadrature encoder that allows for 4000 counts per revolution of the output shaft when counting both edges of both channels. The stepper motor itself has a 1.8° step angle (200 steps/revolution) and each phase draws 1 A at 5.4 V, allowing for a holding torque of 1.9 kg-cm (26 oz-in). 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.

Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and our NEMA 17 aluminum bracket offers a variety of options for mounting this stepper motor in your project.

This stepper motor is also available without an encoder.

Quadrature encoder

The integrated quadrature encoder operates from 5 V and has a resolution of 1000 P/R, which allows for 4000 counts per revolution (CPR) of the output shaft when counting both edges (i.e. rising and falling) of both channels (i.e. A and B). In addition to the A and B channel outputs, the encoder has a home channel, Z, that pulses once per revolution and can be used for absolute positioning. The encoder also has outputs for the inverse of A, B, and Z. A 15 cm (6″) encoder cable is included.

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 (e.g. RepRap)
  • Laser cutters
  • Pick and place machines
  • Linear actuators
  • Hard drives
