Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Exact gear ratio: 25×30×28×4010×10×12×10=70:1

April 2014 update: We have changed the gear ratio in this product’s name from “67:1” to “70:1” so the name more accurately reflects the product. The product itself has not changed.

Dimensions

Dimensions of the 37D mm metal gearmotor with 64 CPR encoder. Units are mm over [inches].

Warning: Do not screw too far into the mounting holes as the screws can hit the gears. We recommend screwing no further than 3mm (1/8") into the screw hole.
