This gearmotor consists of a medium-power, 12 V brushed DC motor combined with a 74.83:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 3591.84 counts per revolution of the gearbox?s output shaft. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox.
Key specs at 12 V: 100 RPM and 200 mA free-run, 125 oz-in (9 kg-cm) and 2.1 A stall.
Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these gearboxes, the recommended upper limit for instantaneous torque is 200 oz-in (15 kg-cm); . Stalls can also result in rapid (potentially on the order of a second) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP) motors; a general recommendation for brushed DC motor operation is 25% or less of the stall current.
