N20 gearmotor with encoder and wheel

This custom made N20 size metal gear motor comes with a built-in quadrature encoder and a 42mm diameter silicon rubber tire.Quadrature encoders are used in advanced robotics for speed control, precise turns and movements, distance calculations and dead reckoning.In order to function well with lower voltages we reduced the impedance to 13 ohms. Here is a mounting bracket for this type of motor.SpecificationsRecommended voltage range for motors: 6vRecommended voltage for encoder circuitry: 3 to 5VDCGear ratio 1:30The encoders are connected to the input shaftRevolutions per minute: @6VDC no load = 500 rpmRevolutions per minute: @6VDC with load = 375 rpmToque kg*cm = 0.35Stall torque kg*cm= 0.4Motor stall current @6VDC = 550mAPinoutM1 — Motor contact 1 (connect your motor driver here)GND — GND for encoder circuitryC1 — output of first encoderC2 — output of second encoderVcc — 3 to 5VDC for encoder circuitryM2 — Motor contact 2 (connect your motor driver here)DocumentsTutorial: Motor Encoders with Arduino
