PM15S-020-CTA6

The PM15S-020-CTA6 is a miniature PM (permanent-magnet, can-stack) stepper motor. In the PM part-number scheme, the 15 gives the body diameter of about 15 mm and the 020 gives 20 full steps per revolution, which is an 18° step angle. Small PM steppers like this are used in printers, valves and other compact mechanisms, and they suit makers who need repeatable movement in a tight space.

Tip: Count the wires before choosing a driver: a 4-wire motor is bipolar and needs an H-bridge driver such as the DRV8833 or L293D, while a 5- or 6-wire motor can run unipolar from a ULN2003. Find the coil pairs with a multimeter and check the rated voltage before powering it.
