Availability: Back Order
Item #: GM15 -

Looking for a tiny gear motor? Now comes the 25:1 Pager Motor, measuring under 6mm (0.235") diameter, with an overall length of 20.1mm (0.79"), which is smaller than many pager motors! The output shaft is grooved for a 1.5mm radius belt, but it's easily modifiable. It weighs only 1.3grams! 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...

81:1 Geared Pager Motor
Price: $12.00

Availability: In Stock
Item #: GM10 -

81:1, 454RPM, 20mA (220mA stall) at 6V gives 3.17 in-oz torque. These little gear motors measure 20.8 x 29.0 x 25.4mm (0.82 x 1.14 x 1.00") and weigh in at 4.7g (0.17oz). The square output shaft measures 3.56mm (0.14") per side, and the leads measure 5cm (1.95") long. They're a bit funky in that they're not continuous rotation by default. They have a self-centering spring, so applying DC power will result in a 60 degree swing in one direction. Reversing power swings the output arm 60 degrees...
