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 268 RPM and a gear reduction of 1:19. They work great on our robots as well as your own applications. These are excellent geared motors for robots.
