MFR. No. : GM7-2
STOCK No. : 2641-FA5-2
The GM7 which is a baby version of our popular GM3 gear motor.
Designed by Mark Tilden to have tighter tolerances and better
performance than a regular toy-style motor these smaller quicker
120:1 gear reduction ratio'd motors are sure to stir ideas!
This gear motor starts rotation at 0.58 volts turning 7RPM drawing
only 46.5mA. At 6 volts this unit really humms spinning at 146RPM
and drawing 92mA no-load (524mA stall producing 23.78in*oz torque).
These units work very well on solarengine circuits.
Like it's big-brother this gear motor also has a built-in safety
clutch which engages at approximately 25in*oz (at 6.5V / 650mA).
This motor also has a unique 2mm (0.08'') crest diameter chrome-finish
splined shaft can be pushed through the output gear to either side
of the motor and is also solder-able!
(If you do want to solder to it yank the shaft right out solder
and then press it back in).
These motors have an overall size of 58.0mm x 24.8mm x 22.3mm
(2.28'' x 0.98'' x 0.88'') and weigh in at only 19 grams (0.67oz).
