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.
The Dynamixel MX-28R RS-485 Servo is the newest generation servo from Robotis. Equipped with an ARM Cortex M3 features a PID control algorithm and provides feedback information such as speed, temperature, position and load.
