You know and love the GM15, but hate the pulley shaft? Ok, ok - here's a more standard "D" shaft configuration! It's still a tiny pager motor planetary gearhead 25:1 reduction, with all the same performance specifications:

Measuring under 6mm (0.235") diameter, with an overall length of 19.15mm (0.753"), which is smaller than many pager motors! The output shaft is 1.95mm (0.077"), with a flat machined on 1.45mm (0.057" )from the shaft diameter, with an overall shaft length of 2.55mm (0.1").

It's designed for 3V nominal operation, giving 920RPM drawing 100mA. At stall, you get over 0.49in*oz or 35.28gm*cm of torque!

We're quite excited about these motors; they're quality made, inexpensive, and tiny! We expect to see lots of nano-sumo robots (25mm cube, or one cubic inch!) built out of these...

Please see the GM15 for mechanical/technical data.
