50:1 Metal Gearmotor 37Dx54L mm with 64 CPR Encoder
This 2.54" x 1.45" x 1.45" gearmotor is a powerful 12V motor with a 50:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 1856 counts per revolution of the gearbox's output shaft. These units have a 0.61"-long, 6 mm-diameter D-shaped output shaft.
Key specs at 12 V: 200 RPM and 300 mA free-run, 170 oz-in (12 kg-cm) and 5 A 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 15.5 mm apart. You can use our custom 37D mm 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.
