This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution) and a holding torque of 1.9 kg-cm (26 oz-in). Each phase draws 1 A at 5.4 V. 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. For more information, see the datasheet (385k pdf).
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:
This is a bidirectional level shifter used to step down or up signals from 1.8V to 5V range.
