67:1 Metal Gearmotor 37Dx57L mm
This 2.13" x 1.45" x 1.45" gearmotor is a powerful brushed DC motor
with 67:1 metal gearbox intended for operation at 12V.
These units have a 0.61"-long, 6mm-diameter D-shaped output shaft.
This gearmotor is also available with an integrated encoder.
Key specs at 12V: 150RPM and 300mA free-run, 200oz-in (14kg-cm) and 5A stall.
The face plate has six mounting holes evenly spaced around the outer edge threaded for M3 screws.
These mounting holes form a regular hexagon and the centers of neighboring holes are 15.5mm apart.
You can use our custom 37D metal gearmotor bracket (shown in the left picture below)
to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.
Please note that unlike our smaller metal gearmotors, these 37D mm gearmotors have output shafts with a diameter of 6mm.
The Pololu universal aluminum mounting hub for 6mm shafts can be used to mount our larger
Pololu wheels (80mm- and 90mm-diameter) or custom wheels
and mechanisms to the gearmotor’s output shaft (see the right picture above).
The picture below shows the dimensions (in mm) of the 37D mm line of gearmotors.
The value of X is 22mm for the 19:1 37Dx52L mm and 29:1 37Dx52L mm versions,
24mm for the 50:1 37Dx54L mm and 67:1 37Dx54L mm versions,
and 26.5mm for the 100:1 37Dx57L mm and 131:1 37Dx57L mm versions.
