This 224:1 gearmotor (gearbox with motor) is a great low-cost
alternative to modified hobby servos.
The low-current motor & compact size of 2.78" x 1.06" x 0.91"
(70.5 x 27 x 23 mm) makes this unit an attractive choice for small robot
designs.
At 5 V, the gearbox and motor provide 50 oz-in of torque and 38 RPM,
which is slightly slower than a servo. The free-running current is
52 mA,
and the stall current is 600 mA. A built-in safety clutch engages at
approximately 60 oz-in.
This gearmotor comes pre-assembled, with the gears fully enclosed.
There are built-in mounting holes, and the output shaft is 7mm in
diameter with two sides flattened.
