These Planetary Gearboxes are nominally 32mm in diameter with permanent magnet reversible DC motors. We carry 12VDC and 24VDC motors and range from 8 to 265 RPM. Several right angle gearboxes. Several motors have encoders.
These tiny gearmotors are available in a range of gear ratios. 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.
We have a bunch of power supplies laying around. This is a bag of 3 randomly selected 12VDC power supplies (wall warts). 110VAC input. About 6 inches of wire with no ends. If you need a power supply (wall wart), you can't beat this deal.
