Custom Gearmotor: Dual Planetary DC Motor
Featured Product from Groschopp, Inc.
The dual output Permanent Magnet DC (PMDC) Planetary Gearmotor, by Groschopp Inc, drives two hinged arms on an automated surgical table used in orthopedic surgery. It was designed so that two hinged arms could be positionally aligned, and their movement synchronized at all times.
The traditional solution of link chains, belts, and pulleys has a greater margin of operational error and it is significantly more difficult to synchronize the movement and alignment of the two hinged arms. This design provided the desired operational performance, AND it eliminated the need for two separate motors - which are also difficult to synchronize and are a more expensive solution.
This is a custom designed, high torque, fractional HP PMDC motor with two planetary speed reducers, one on each end, driven by the same motor shaft. Because the same motor drives both outputs there is both mechanical AND electrical "linkage". If two separate motors were used, a more complex common control would be required to achieve the same positioning and synchronized movement. In addition to eliminating the need for two separate motors, this design essentially eliminates the need for a more complex (and expensive) control scheme to provide electrical linkage.
