Motion Facets and Considerations

The following is a sample of the many aspects of motion that a seasoned motion engineer deals with on a daily basis.

  • Point-to-point motion
  • Controller bandwidth & feedback precision
  • Interpolation
  • Constant velocity scanning (time or position based)
  • Load carrying capacity
  • Acceleration
  • Velocity
  • Settling time
  • Anti-jerk smoothing
  • Position stability at rest
  • Throughput
  • Duty cycles
  • Heat (generation & dissipation) Ambients (temperature, humidity, & pressure)
  • Cleanroom (particle generation & containment)
  • Vacuum environment Accuracy
  • Repeatability
  • Straightness of travel
  • Flatness of travel
  • Pitch, roll, & yaw
  • Single stage
  • Stacked multiple stages
  • Split multiple stages
  • Orthogonality
  • Horizontal motion
  • Vertical motion
  • Support structure
  • Vibration isolation (internal & external)
  • Digital I/O timing coordination
  • Analog I/O control
  • Safety (mechanics & personnel)
  • Utilities (electrical & pneumatic)
  • Vision assisted motion
  • Interferometer feedback (retro & plane mirror)
