PM15S-020-NSF7

The PM15S-020-NSF7 is a micro PM (permanent-magnet, can-stack) stepper motor about 15 mm across. The 020 in the part number means 20 full steps per revolution, so the shaft turns 18° per step, or 9° in half-step mode. It is a handy motor for makers, students and repair technicians who need precise movement in very little space.

What's in the Box

• 1 × PM15S-020-NSF7 stepper motor

Tip: Use a multimeter to find the two coils before wiring, then connect them to a driver such as the DRV8833 or L293D. If the motor only vibrates, swap the two wires of one coil or slow down the step rate.
