Motor with 64 CPR Encoder for 37D mm Metal Gearmotors (No Gearbox, Spur Pinion)

Pololu item #: 2821
Brand: Pololu
Status: Special Order Only 
RoHS 3 compliant

This product has been discontinued.

This motor has been replaced by a functionally identical version that works with our newer 37D gearmotors with helical pinion gears. It is now only available by large-volume special order; please contact us for more information.

This is the motor and encoder portion of our 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 spur pinion 37D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes. It is intended for use at 12 V, though the motor can begin rotating at voltages as low as 1 V.

Key specifications:

12 V 10,000 RPM, 150 mA 0.5 kg⋅cm (7 oz⋅in), 5.5 A

Dimensions

Size: 34.5D × 46.5L mm1
Weight: 110 g

General specifications

Gear ratio: 1:12
No-load speed @ 12V: 10000 rpm
No-load current @ 12V: 0.15 A
Stall current @ 12V: 5.5 A3
Stall torque @ 12V: 0.5 kg·cm3
No-load speed @ 6V: 5000 rpm4
No-load current @ 6V: 0.1 A4
Stall current @ 6V: 3.0 A4
Stall torque @ 6V: 0.3 kg·cm4
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 is likely to 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.
