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Status: Obsolete 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This gearmotor has been replaced by a functionally identical version that uses helical pinion gears for the first stage of the gearbox to reduce noise and improve efficiency.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 12V brushed DC motor with a 18.75:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 1200 counts per revolution of the gearbox’s output shaft. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available without an encoder.

Key specifications:

voltage no-load performance stall extrapolation
12 V 530 RPM, 200 mA 8.5 kg⋅cm (120 oz⋅in), 5.5 A

What material is the gearbox output shaft made of, and can I get the shaft customized?
The shaft is composed of hardened stainless steel. Some customization is generally possible (e.g., different length or no D-shaft) for sufficiently high-volume orders. If this is something you are interested in, please email us.
