Small DC servo motor with high resolution encoder and planetary + spiroid gear combination.
maxon motor Australia have just implemented the first combination of a small PMDC servo motor with a dual gearhead combination using both planetary and Helicon technology. The application is a gyro stabilised cinematography camera mount with three degrees of freedom.
The customer required both inline and right angle gearboxes for the different axis but also needed the same ratio throughout. Worm gearheads could not be used because of their inherently low efficiency and a helical of the correct ratio would be too large for the torque requirements. The solution was to use a combination of a ceramic planetary gearhead and the new spiroid gearhead technology. The multiplication of the two gearbox efficiencies is an impressive 72% while the equivalent ratio in a single ceramic planetary is only marginally better at 75%. The single helicon tooth form in itself has an efficiency of 90% Contact maxon motor Australia for further information or assistance.
