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 brushed permanent magnet DC gearmotors have a rated speed of 191 RPM and a gear reduction of 1:27. They work great on our robots as well as your own applications. Former item number TD-014-195. These are excellent geared motors for robots.
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A.
