Sanyo Miniature Stepper Motor: Bipolar, 200 Steps/Rev, 14×30mm, 6.3V, 0.3 A/Phase

Bipolar stepper motor wires are terminated with bare leads.

Sanyo bipolar stepper motor wiring diagram.

Overview

This tiny bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 300 mA at 6.3 V, allowing for a holding torque of 66 g-cm (0.92 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. It is available with a single shaft or double shaft. For more information, see the datasheet (125k pdf).

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
