Pololu 5:1 Micro Metal Gearmotor HP 6V w/ 12 CPR Encoder, Back Connector
Integrates compact 5:1 metal gearbox
Features 6V no-load speed of 6100 RPM
Includes 12 CPR Hall effect encoder
Utilizes robust 10×12 mm gearbox
Delivers 0.11 kg⋅cm stall torque
The Pololu 5:1 Micro Metal Gearmotor HP 6V w/ 12 CPR Encoder, Back Connector is a compact brushed DC motor featuring a robust metal gearbox with a cross-section of 10×12 mm. It is equipped with a 9 mm long, 3 mm diameter D-shaped output shaft. This gearmotor integrates a two-channel incremental Hall effect encoder, which detects the rotation of a magnetic disk located on the rear extension of the motor shaft. The encoder provides a resolution of 12 counts per revolution (CPR) of the motor shaft, which can be adjusted by multiplying with the gearbox reduction factor to determine the counts per revolution of the gearbox output.
The encoder is connected via a 6-pin JST SH-style male connector, compatible with corresponding cables and connector boards. The back connector orientation aligns parallel to the motor, ensuring efficient integration into various applications. The motor terminals are accessible through designated pins, allowing for flexible operation by alternating the polarity of the power supply to the motor leads. The sensors are powered through specific pins, with the quadrature outputs delivering digital signals that indicate motor direction and speed.
This gearmotor is designed for a voltage of 6 V, offering a no-load performance of 6100 RPM and a stall torque of 0.11 kg⋅cm. The gear ratio is approximately 4.995:1, utilizing durable brass plates. The encoder's built-in hysteresis in the sensors' comparators helps prevent erroneous signals, ensuring reliable performance.
