Pololu 9.7:1 Metal Gearmotor 25Dx63L mm LP 12V w/ 48 CPR Encoder
Integrates a 48 CPR quadrature encoder
Offers 464.64 counts per revolution
Features a 9.68:1 metal spur gearbox
Compatible with diverse mounting hubs
Provides precise speed and direction control
The Pololu 9.7:1 Metal Gearmotor 25Dx63L mm LP 12V w/ 48 CPR Encoder is a sophisticated component designed for precision motion control applications. This gearmotor integrates a low-power, 12 V brushed DC motor with a 9.68:1 metal spur gearbox, offering a compact cylindrical form with a diameter of just under 25 mm. The motor features a D-shaped output shaft, 4 mm in diameter, extending 12.5 mm from the gearbox face plate, ensuring compatibility with various mounting and coupling options.
A notable feature of this gearmotor is its integrated 48 CPR quadrature encoder, which provides 464.64 counts per revolution of the gearbox’s output shaft. This high-resolution encoder is facilitated by a two-channel Hall effect sensor that detects the rotation of a magnetic disk on the motor shaft. The encoder outputs square waves that indicate both the speed and direction of the motor, making it ideal for applications requiring precise control.
The gearmotor is versatile, with options for different gear ratios and power levels, all maintaining the same 25 mm diameter case and 4 mm output shaft. This allows for easy interchangeability to meet varying design requirements. The motor and encoder are connected via six color-coded leads terminated by a 1×6 female header, compatible with standard 0.1″ male headers.
Mounting is facilitated by two M3 threaded holes on the face plate, and the output shaft is compatible with Pololu multi-hub wheels and various mounting hubs. This gearmotor is suitable for integration with a range of motor controllers and drivers, providing flexibility for diverse control interfaces.
