This gearmotor is a compact (1.50" x 0.59" x 0.47"), high-quality motor with 35:1 metal gearbox. These units have a 0.365"-long, D-shaped output shaft that matches the micro metal gearmotor output shafts.
Gearmotor Dimensions:This motor has a long (0.365" or 9.27 mm, not 8mm as shown in the drawing below), D-shaped metal output shaft that matches the Pololu wheel 42×19 mm, Pololu wheel 32×7 mm, and Solarbotics RW2 rubber wheel. The brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). Note: this gearmotor is not compatible with our Sanyo-style micro gearmotor mounting brackets (products 989 and 1089).
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. Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor. At 6 V, this gearmotor will have a no-load RPM of around 350 with a free-run current of 70 mA, a stall current of 1.5 A, and a stall torque of around 35 oz-in (2.52 kg-cm).
Specs for the metal gearmotors running at 6 V:
* The stall torque should only be considered a rough estimate. |
