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:

General specifications

Gear ratio: 1:12
No-load speed @ 12V: 10000 rpm
No-load current @ 12V: 0.2 A
Stall current @ 12V: 5.5 A3
Stall torque @ 12V: 0.5 kg·cm3
No-load speed @ 6V: 5000 rpm4
No-load current @ 6V: 0.15 A4
Stall current @ 6V: 3.0 A4
Stall torque @ 6V: 0.3 kg·cm4
Motor type: 12V
Lead length: 20 cm5
Encoders?: Y
Encoder resolution: 64 CPR

Notes:

1
Length measurement does not include motor shaft or pinion gear.
2
This motor does not have a gearbox.
3
Stalling can damage the motor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. As the motor heats up, as happens as it approaches an actual stall, the stall torque and current decrease.
4
This motor will run at 6 V but is intended for operation at 12 V.
5
May vary by a few centimeters.
