100:1 Metal Gearmotor 37Dx57L mm with 64 CPR Encoder
This 2.71"×1.45"×1.45" gearmotor is a powerful 12V brushed DC motor with
a 102.083:1 metal gearbox and an integrated quadrature encoder that
provides a resolution of 64 counts per revolution of the motor shaft,
which corresponds to 6533 counts per revolution of the gearbox’s output shaft.
These units have a 0.61"-long, 6mm-diameter D-shaped output shaft.
This gearmotor is also available without an encoder.
Key specs at 12V: 100RPM and 300mA free-run, 220oz-in (16kg-cm) and 5A stall.
Gearmotor Dimensions
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 37Dmm 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 37Dmm 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 diagram 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.
Note that the encoder PCB and magnetic disc are not shown in this dimension diagram.
The encoder assembly extends an additional 12.5mm beyond the rear of the motor.
