Metal Gearmotor with Encoder - 12V (9.7:1)

This gearmotor combines a low - power 12V brushed DC motor with a 9.7:1 metal spur gearbox. It features an integrated 48 CPR quadrature encoder on the motor shaft, which offers 464.64 counts per revolution of the gearbox’s output shaft. With a cylindrical shape and a diameter just under 25 mm, it has a 4 - mm diameter D - shaped output shaft that extends 12.5 mm from the gearbox face plate. A two - channel Hall effect encoder senses the rotation of a magnetic disk on the motor shaft's rear protrusion. The quadrature encoder gives a resolution of 48 counts per revolution of the motor shaft when counting both edges of both channels. The motor/encoder comes with six color - coded, 8″ (20 cm) leads terminated by a 1×6 female header with a 0.1″ pitch. The Hall sensor needs an input voltage (Vcc) between 3.5 and 20 V and draws a max of 10 mA. The A and B outputs are square waves, about 90° out of phase, with the transition frequency indicating motor speed and the order showing direction. Note that the listed stall torques and currents are theoretical. Stalling or overloading can reduce the gearmotor's lifespan or cause immediate damage. The recommended continuous load limit is 4 kg⋅cm (55 oz⋅in), and the intermittent torque limit is 8 kg⋅cm (110 oz⋅in). General advice for brushed DC motor operation is to keep the current at 25% or less of the stall current. Key features include 12V voltage, 0.9A stall current, 60mA no - load current, 9.7:1 gear ratio, 580 RPM no - load speed, 1.3 kg⋅cm (18 oz⋅in) stall extrapolation at 0.9A, and 1.8W max power.

Using this gearmotor is quite straightforward. First, make sure to connect the six color - coded leads to the appropriate power source and control system using the 1×6 female header. The input voltage for the Hall sensor should be between 3.5 and 20 V. You can then monitor the motor's speed and direction through the A and B outputs. When using the motor, avoid stalling or overloading it. The continuous load should not exceed 4 kg⋅cm (55 oz⋅in), and for short - term use, don't go beyond 8 kg⋅cm (110 oz⋅in). To keep the motor in good condition, it's a good idea to run it at 25% or less of the stall current. If you notice the motor getting too hot, stop using it immediately to prevent damage to the windings and brushes. Regularly check the connections to ensure they are secure. Also, keep the motor clean and free from dust and debris.
