Motor

100:1 Metal Gearmotor 37Dx73L mm with 64 CPR Encoder This gearmotor is a powerful 12V brushed DC motor with a 102.083:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 6533 counts per revolution of the gearbox’s output shaft. These units have a 0.61"-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available without an encoder. Key specs at 12 V: 100 RPM and 300 mA free-run, 220 oz-in (16 kg-cm) and 5 A stall. Details for item #2826 Exact gear ratio: 25×30×28×28×3010×10×12×12×12≈102.083:1 Dimensions   ..

This cylindrical, 2.54" x 0.98" x 0.98" brushed DC gearmotor with a 46.85:1 metal gearbox is a lower-current alternative to the HP version. It has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 2249 counts per revolution of the gearbox’s output shaft. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. These motors are intended for use at 6 V. In general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range, though they can begin rotating at voltages as low as 1 V. Higher voltages could start negatively affecting the life of the motor. Gearmotor Dimensions These gearmotors have output shafts with a diameter of 4 mm. The..
