BALANCING DEFINITION

• Balance To change the mass distribution of a
  rotor in such way that the axis of rotation and
  the axis of inertia coincides.

4
SOME CAUSES OF UNBALANCE

• Excentricities during design or fabrication.
• Fabrication defects (porosities)
• Wear, corrosion or dirt.
• Distortion

PARAMETERS TO MEASURE

• 1. Angular Velocity.
• 2. Vibration Amplitude at 1 x RPM.
• 3. Phase of Vibration at 1 x RPM relative to
  Rotor.
• 1 3 ? Strobe light or Photocell.
• 2 3 ? Acelerometers, sismic pickup and
  proximity probes
