SparkFun Planetary Gearmotor

SparkFun Planetary Gearmotor is a simple ~140RPM, no-load, DC planetary gearmotor. The motor is ideal for various applications like robotics, electric locks, household automation, and small actuators. The supply voltage range is 6VDC to 24VDC with the polarity marker at the base of the motor. The planetary gearbox is mounted on top of the motor housing. This gives the motor a relatively large stall torque for its size. The overall body of the motor is made of metal, with the exception of the set of planet gears on the first input gear set, which are plastic. This planetary gearmotor has an overall body dimension of 76.1mm length with a 22mm diameter while the drive shaft is 12mm in length and 6mm in diameter.
