5:1 Micro Metal Gearmotor [228]

This gearmotor is a miniature (0.94" x 0.39" x 0.47") high-quality low-current motor with 5:1 metal gearbox similar to Sanyo˙s popular 12 mm gearmotors. These units have a 0.365"-long 3 mm-diameter D-shaped output shaft.

Key specs at 6 V: 2500 RPM and 50 mA free-run 1 oz-in (0.1 kg-cm) and 0.36 A stall.

These tiny high-quality 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 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.

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.

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 0.35 oz (10 g).
