1000:1 Micro Metal Gearmotor
This miniature, high-torque gearmotor has a 1000:1 gearbox, making it a great choice for applications
requiring fine control at very low speeds.
These units have a 0.365"-long, 3mm-diameter D-shaped output shaft.
Key specs at 6V: 14RPM and 40mA free-run, 70oz-in (5kg-cm) and 0.36A stall.
(Note: stall torque and current specifications are theoretical values; stalling the motor will damage the gearbox.)
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.
With no load, the 1000:1 micro metal gearmotor HP
output shaft turns at approximately 32RPM at 6V, and we were able to achieve
rotation rates of around 2.5RPM at 0.5V on a test unit (note that performance will vary slightly from unit to unit).
The lower-power 1000:1 micro metal gearmotor is even slower,
with a no-load rotation rate of approximately 14RPM at 6V, and we were able to
a achieve smooth rotation speed of around 1RPM at 0.6V on a test unit.
These motors are intended for use at 6V, 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 – 9V range
(rotation can start at voltages as low as 0.5V).
Lower voltages might not be practical, and higher voltages could start negatively affecting the life of the motor.
Micro Metal Gearmotor Versions
The micro metal gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and offer a choice
between two different motors: high-power (HP) and standard.
With the exception of the 1000:1 gear ratio versions, all of the micro metal gearmotors have the same
physical dimensions, so one version can be easily swapped for another if your design requirements change.
Please see the micro metal gearmotor comparison table for detailed specifications of all our micro metal gearmotors.
This dynamically-sortable table can help you find the gearmotor that offers the best blend of speed, torque,
and current-draw for your particular application.
A more basic comparison table is available below.
Some versions of the gearmotors are sold with an additional 1mm-diameter output shaft that protrudes
from the rear of the motor.
This 4.5mm-long rear shaft rotates at the same speed as the input to the gearbox and offers a way to add
a custom-built encoder to provide motor speed or position feedback.
