A Thousand Spins

This small reversible DC motor from JEI runs on 3-6VDC. At 6V it draws 350mA no load and stalls at 1.9A. Spins approx 1000 rpm and approx half that at 3V. Great for science fairs, hobbies and any kind of project that needs spinning. Measures 1-3/16" long x 7/8" dia with a 1/4" x 1/16" shaft and tiny contacts for power that you'd best solder.

No Mount Motor

Our motorman, CJ, called this reversible 12-24VDC motor strange, mostly because it has the power contacts mounted on the face, bracketing the 11/16" x 1/8" mostly striated shaft, and has no mounting brackets. But that shouldn't stop a clever person like you. (Hint: it was probably made to fit into a sleeve of some sort.) At 12VDC, draws 100mA no load, stalls 850mA and spins approx 900 rpm; at 24VDC, draws 150mA, stalls 2.2A and spins approx 1800 rpm.  Measures 2-1/4" x 1-13/32" dia.
