Another area that can offer substantial savings is insuring that all motors in service are healthy. AC induction motors are subject to many different
failure modes. Broken rotor bars, cracked end rings, high resistance joints (bad welds) excessive air gap eccentricity, and shorted stator windings are typical problems, particularly on large motors subjected to multiple start/stop cycles.
