2298-POLOLU Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 42×11.6mm, 3.5V, 1 A/Phase
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.
This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 3.5 V, allowing for a holding torque of 850 g-cm (12 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.

Dimensions
The following diagram shows the stepper motor dimensions in mm. The dimension labeled “L” is 11.6 mm. This stepper motor has a single output shaft with a length of 5 mm from the mounting face and a diameter of 5 mm. This shaft works with our 5 mm universal mounting hub.
We also carry a stronger, taller version of this stepper motor where “L” in the above diagram is 18.6 mm and all other dimensions are the same.
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
