This gearmotor is designed for low-voltage power-efficiency, but it isn't scared of generating a bit of torque. And the output shaft is shaped just like the GM2/3/8/9 for full accessory compatibility!

It's a small, slow, power-efficient but torquey motor, weighing in at only 35g (1.23oz)! It's a bit bigger than its more powerful brethren, measuring in at 46.7mm (1.84") long, 27.2mm (1.07") wide, and 32.1mm deep (1.26") excluding shaft.

Here are the basic stats:

Voltage	Current	RPM	Torque	Stall Current
0.39V	15mA	1.03	Very low	Not measured
3V	19mA	15.8	40 in*oz	0.24A
6V	29mA	32	74 in*oz	0.46A
9V	51mA	46.2	Not measured	Not measured
12V	94mA	62	Not measured	Not measured

Please note that we have not tested this unit for compatibility with the Wheel-Watcher encoders...yet!
