Introducing our new line of micro gearmotors! Although these micro gearmotors have a footprint comparable to a micro-size servo and tip the scales at only 0.3oz, they are incredibly powerful. All-metal gears ensure the motor will hold up in even the harshest applications. The extremely versatile gearmotor case (sold separately) provides protection for the gears and offers numerous mounting options to fit a variety of custom applications. These micro gearmotors have a 3mm D-shaft that protrudes from the gearbox. We have several accessories including hubs, pinion gears, couplers and more that will work great with these durable little gearmotors!
