Newer version: The original 37D gearmotor we supplied under this part number used spur pinion gears internally, this has been replaced by a newer version that features helical gears for the first stage of the gearbox. This makes the gearbox a little quieter and more efficient. The performance is otherwise unchanged, and the dimensions are the same, so the new version with helical pinion gears can be used as direct replacements for the original units.

This 57 × 37 x 37mm geared motor is a powerful brushed DC motor with 100:1 metal gearbox intended for operation at 12 V. These units have a 15.5mm-long, 6 mm-diameter D-shaped output shaft.

Key specs at 12 V: 100 RPM and 300 mA free-run, 220 oz-in (16 kg-cm) and 5 A stall.

This powerful brushed DC gearmotor is also available in five other gear ratios.

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 15.5 mm apart. You can use our custom 37D metal gearmotor bracket (see related products below) to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.

The dimensioned picture above shows the dimensions (in mm) of the 37D mm line of gearmotors. The value of X is 22 mm for the 19:1 37Dx52L mm and 29:1 37Dx52L mm versions, 24 mm for the 50:1 37Dx54L mm and 67:1 37Dx54L mm versions, and 26.5 mm for the 100:1 37Dx57L mm and 131:1 37Dx57L mm versions.

Warning: Do not screw too far into the mounting holes as the screws can hit the gears. We recommend screwing no further than 3mm into the screw hole.
