Features reversible motor terminals
Ensures reliable performance with built-in hysteresis
The Pololu 1000:1 Micro Metal Gearmotor HPCB 12V w/ 12 CPR Encoder, Side Connector is a compact brushed DC motor equipped with a metal gearbox. It features a 10×12 mm gearbox cross-section and 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 on the motor shaft's rear protrusion. The encoder provides a resolution of 12 counts per revolution, utilizing both edges of both channels for precise motion detection.
The encoder is equipped with a 6-pin JST SH-style male connector, compatible with corresponding cables and connector boards. The side connector orientation is perpendicular to the motor, ensuring versatile mounting options. The motor terminals are accessible via red and black wires, and the motor can be operated in both directions by alternating the polarity of the power supplied to the leads.
The sensors are powered through designated Vcc and GND pins, with Vcc supporting a range from 2.7 V to 18 V. The quadrature outputs, A and B, are digital signals that indicate motor direction and speed through their phase and frequency. These signals are square waves with approximately 50% duty cycles and are 90° out of phase. The built-in hysteresis in the sensors' comparators prevents false signals during transitions, ensuring reliable performance.
