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 |
Alternatives available with variations in these parameter(s): gear ratio motor type encoders? Select variant…

MATLAB script to plot motor performance curves for Pololu brushed DC gearmotors
This MATLAB script, written by Ali Asgher Mansoor Habiby, plots speed, power, current draw, and efficiency as they vary with torque when you input the gearmotor specifications. It also prints the resistance of the motor, and the current draw and torque at which maximum efficiency and maximum power occur.
