This is a very useful Motor
Gearbox combination supplied as a kit of easy to assemble parts. It
includes a DC motor, supporting framework with all necessary parts and two
sets of gears to give two different gear ratios (1:60 and 1:288). Choice
of gear ratios gives the user greater flexibility in matching speed and
torque to his own particular application. Although this is still very much
a light duty arrangement it makes it much more usable for the robotics
enthusiast than a simple DC motor which tends to have too little torque
and too much speed. The motor is typically used with supplies in the range
3.0v - 6.0v DC
Basic Specifications at 4.5v operating voltage
speed no load at 1:60 ratio is approx 200rpm
speed no load at 1:200 ratio is approx 42rpm
The
diagram above shows the parts included and the two different gear sets
available, specified as number of teeth for each gear position.
