Direct Drive Technology Integration: Virtual

Class Agenda:

1. ETEL motor product line introduction and handbook overview
2. Motor drawings review:
   • Important values to take into account for mechanical design
   • Explanation of important tolerances.
3. Important concepts for mechanical integration:
   • Minimum tolerances for housing and shaft and why they are necessary
   • Rotor & Stator temperatures and the effect of shaft expansion.
4. Encoder positioning reading error:
   • How error is effected by shaft eccentricity and the influence on the machine’s overall accuracy.
     • Due to the internal knowledge available at heidenhain, the topic of encoder selection will remain limited.
5. Mechanically coupling motors:
   • How to achieve proper coupling
   • Explanation of the methods outlined in ETEL’s handbook
   • Influence of coupling accuracy on performance
6. Bearings:
   • How to achieve a stiff preloaded assembly
   • The influence of flatness/concentricity tolerances
7. Complete assembly mounting:
   • Torque Motors:
     • Stator & housing coupling
     • Rotor & shaft coupling
     • Rotor & stator insertion
     • Mounting & dismounting for the purpose of maintenance
     • Explanation of ETEL’s bridge and example of user specific mounting tool
     • Rotor/stator mounting assembly video.
   • Linear Motors
     • Magnetic track mounting
     • Air gap and glider coupling to customer structure (keeping to flatness requirements)
     • Mounting & dismounting for the purpose of maintenance
     • Magnet track/motor mounting assembly video
