YFROBOT Metal Gearmotor GA25 12V with 360 CPR Encoder photoelectric speed measurement Ratio:1:34 but they feature helical gearsOverview: These brushed DC gearmotors have a diameter of 25mm (0. 984 inches) , with all versions available with an integrated quadrature encoder on the motor shaft. The 12V motors provide roughly the same performance at their respective rated voltages. Its motor shaft is a 4mm D shaft. These motors can typically be run at voltages above and below their rated voltage, with lower voltages being less practical and higher voltages beginning to have a
