5:1 Micro Metal Gearmotor
This gearmotor is a miniature (0.94" x 0.39" x 0.47"), low-current brushed DC motor with 5:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft.
Key specs at 6 V: 2500 RPM and 50 mA free-run, 1 oz-in (0.1 kg-cm) and 0.36 A stall.

Dimensions of the Pololu micro metal gearmotors with carbon brushes (HPCB). Units are mm over [inches]. |
In terms of size, these gearmotors are very similar to Sanyo’s popular 12 mm NA4S DC gearmotors, and gearmotors with this form factor are occasionally referred to as N20 motors. The versions with carbon brushes (HPCB) have slightly different terminal and end-cap dimensions than the versions with precious metal brushes, but all of the other dimensions are identical.
Note: The gearbox on the 1000:1 and 1000:1 HP micro metal gearmotors is 12.5 mm long. All of the other micro metal gearmotors have 9mm-long gearboxes, as shown in the above dimension diagram.
