12V Motor with 64 CPR Encoder for 37D mm Metal Gearmotors (No Gearbox, Helical Pinion)
This is the motor and encoder portion of our 12V 37D mm metal gearmotors with 64 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our helical pinion 37D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes.
Key specifications:
| voltage | no-load performance | stall extrapolation |
|---|---|---|
| 12 V | 10,000 RPM, 200 mA | 0.5 kg⋅cm (7 oz⋅in), 5.5 A |

- Is it okay to stall this motor at its operating voltage?
No! Stalls can 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, which means keeping continuously applied loads around 25% or less of the stall torque.
Additionally, for many of our gearmotors with high gear ratios, the extrapolated stall torque is beyond what the gearboxes are designed to handle, and a stall could instantly damage the gears. Make sure to keep applied loads within the published limits for your gearmotor.
- What do the dotted lines mean in the motor performance curves from the datasheet?
- In our motor performance curves, the solid lines show the regions where we actually took measurements while the dotted lines show extrapolations beyond that. For many motors, we took measurements out to about 50% of the stall torque, since continued operation at loads past this point increasingly risk thermal damage to the windings. However, for higher gear ratios, going to 50% of the stall torque exceeds what is safe for the gearbox, so the measurements are further limited to not much past our recommendation for continuously applied loads.
