Geared Motor 120:1 Ratio, 90 degree Shaft


Bookmark and Share
The GM7 is a baby version of the 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 5 volts, this unit really humms, spinning at 145RPM and drawing 88mA no-load (610mA stall producing 20in*oz torque).

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 solderable! (If you do want to solder to it, yank the shaft right out, solder, then press it back in).
