Planetary Gear Pager Motor with a more standard D Shaft
Looking for a tiny pager-motor planetary gearhead 25:1 reduction,?
You know and love the GM15, but hate the pulley-shaft? Ok, ok - here's a more standard "D" shaft configuration!
The GM15A, 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!
