Sanyo Pancake Stepper Motor: Bipolar, 200 Steps/Rev, 50×16mm, 5.9V, 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 2.2 kg-cm (30 oz-in), and each phase draws 1 A at 5.9 V. This stepper motor’s flat profile (21 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 5.9 V, allowing for a holding torque of 2.2 kg-cm (30 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.

More specifications are available in the datasheet (352k pdf).
The following diagram shows the stepper motor dimensions in mm. The dimension labeled “L” is 16 mm. Though the dimension diagram below shows output shafts on both sides, (on the side with the mounting plate) with a length of 5 mm and a diameter of 5 mm. This shaft works with our 5 mm universal mounting hub.
We also carry a thinner version of this stepper motor where “L” in the above diagram is 11 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:
- CNC machines
- 3D printer/prototyping machines (e.g. RepRap)
- Laser cutters
- Pick and place machines
- Linear actuators
- Hard drives

Note: Sanyo Denki originally called this product the “SANMOTION F2 stepping motor model SS2502-5041”, but as of October 2014, they are transitioning to using the new part number SS2502-8040. This is only a part number change; the product itself is exactly the same.
