Sanyo Miniature Stepper Motor: Bipolar, 200 Steps/Rev, 14×30mm, 6.3V, 0.3 A/Phase, Double Shaft
This tiny, double shaft 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). With a weight of 28 g, this is the smallest stepper motor we carry.

Sanyo bipolar stepper motor wiring diagram.
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.
Our 4 mm universal mounting hub can be used to mount objects on the stepper motor’s 4 mm-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:
- CNC machines
- 3D printer/prototyping machines (e.g. RepRap)
- Laser cutters
- Pick and place machines
- Linear actuators
- Hard drives
