100:1 Metal Gearmotor 37Dx57L mm 12V (Spur Pinion)

Pololu item #: 1106
Brand: Pololu
Status: Obsolete 
RoHS 3 compliant

This product has been discontinued.

This gearmotor has been replaced by a functionally identical version that uses helical pinion gears for the first stage of the gearbox to reduce noise and improve efficiency.

This gearmotor is a powerful brushed DC motor with 102.08:1 metal gearbox intended for operation at 12 V. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available with an integrated encoder.

Key specifications:

Notes:

1
Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals). See dimension diagram for details.
2
D shaft.
3
Stalling is likely to damage the gearmotor. 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
Stalling is likely to damage the gearmotor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. This motor will run at 6 V but is intended for operation at 12 V.
