Metal Gearmotor with Encoder - 12V (9.7:1)
This 12V brushed DC gearmotor features a 9.68:1 metal spur gearbox and an integrated 48 CPR quadrature encoder on the motor shaft, providing 464.64 counts per revolution of the gearbox output. The two-channel Hall effect encoder senses a magnetic disk on the motor shaft, delivering speed and direction feedback for precise closed-loop control.
The motor has a cylindrical form factor just under 25mm in diameter, with a 4mm D-shaped output shaft extending 12.5mm from the gearbox face plate. Six colour-coded leads (20cm) terminate in a 1×6 female header with 0.1" pitch for easy connection.
