These standard gearmotors are incredibly tough and feature full metal gears to help you drive wheels, gears, or almost anything else that needs to turn. They have a gear ratio of 300:1 and operate up to 12 volts and deliver a stall torque of 368 oz-in. and a max speed of 10 RPM. Each standard gearmotor sports a 6mm diameter D-shaft.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Got this to help a friend build a caudron stirring witch kind of thing for Halloween - the motor works great for that purpose.
Has been reliable and durable to date. No issues with the operation of it yet. Very pleased at this point.
Used this for winding custom coils. It does not bog down when when you need a bit of torque. Got all the mounting brackets on Sparkfun.com also.
Beautiful Quality Product, Works Great, Great Price, Perfect! Thank You SparkFun
Drawing is missing dimensions for the (kind of important) D part of the shaft. I'm measuring 5.46mm from flat to other side of shaft (relatively shallow D)
hello, general comment, people from all over the world order on this site, is this possible to have the specs in METRICS as well as whatever weird fantasy system you like to use over there, I can bear converting inches and feets to cm and meter but I'm having a bit more of a problem with whatever "oz-in" is and this is freaking annoying. (specially when you mix it up a bit with things like "Shaft Size: 6mm Diameter x 0.715” Length" ) thanks.
Maybe when your country lands on the moon we can talk. Otherwise, learn to convert units like most of us educated people have to do from time to time!
Is there a data sheet for this motor? I'm curious about the shaft bearing and how much radial load it can take.
Is there a way to calculate how the motor would act at 5V? In terms of torque and speed?
For a DC motor, stall torque and no-load speed are (theoretically) proportional to the voltage: 5v/12v = 0.4167 368oz-in * 0.4167 = 153oz-in 10RPM * 0.4167 = 4.167RPM.
So @ 5v, stall torque is 153oz-in and no load speed is 4.167RPM.
