These tiny, high-torque gearmotors have the highest gear ratio of any motor we sell, which makes them a great choice for applications that require extremely low motor speeds. The lower-power 1000:1 micro metal gearmotor has a no-load rotation rate of approximately 14 RPM at 6 V, and we were able to a achieve smooth rotation speed of around 1 RPM at 0.6 V on a test unit.
These motors are intended for use at 6 V, though 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 (rotation can start at voltages as low as 0.5 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
The diagram below shows the dimensions for this gearmotor. The 1000:1 gear ratio version of the micro metal gearmotor has a longer gearbox than other micro metal gearmotor versions (12.5 mm for the 1000:1 compared to 9 mm for all gear ratios). All the other dimensions match those of the other micro metal gearmotor versions.
The gearbox has a long (0.365" or 9.27 mm), 3 mm-diameter D-shaped metal output shaft, and the brass faceplate has two mounting holes threaded for M1.6 screws (1.6 mm diameter, 0.35 mm thread pitch). It weighs approximately 0.37 oz (11 g).
Note: Due to the longer gearbox, the 1000:1 micro metal gearmotors do work with the encoder for Pololu wheel 42×19mm. These gearmotors can be used with our micro metal gearmotor bracket and extended bracket, but these brackets will not cover the entire gearbox the way they do when used with other gear ratios of micro metal gearmotors.
