brand: SainSmart SKU: 101-60-155
$22.99

This 2.54" × 1.45" × 1.45" gearmotor is a powerful 12V brushed DC motor with a 29:1 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.

Available in six different gear ratios and features an integrated quadrature encoder with 64 counts per revolution (CPR) of the motor shaft.

 

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 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. 

Using the Encoder

A two-channel Hall effect encoder is used to sense the rotation of a magnetic disk on a rear protrusion of the motor shaft. The quadrature encoder provides a resolution of 64 counts per revolution of the motor shaft. To compute the counts per revolution of the gearbox output, multiply the gear ratio by 64.
