POLOLU-4750 · Pololu
This is the motor and encoder portion of our 12V 37D mm metal gearmotors with 64 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our helical pinion 37D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes. Key specifications: voltage no-load performance stall extrapolation 12 V 10,000 RPM, 200 mA 0.5 kg⋅cm (7 oz⋅in), 5.5 A (Pololu item #4750)
