Motor Repair Specification

This is a brief outline specification for a typical motor repair.

  • Each motor is run and a vibration conformance check is carried out.
  • The motor is stripped and a root cause failure analysis is performed. This includes a strip-down and analysis of the bearings.
  • The motor windings are tested using Baker surge test equipment.
  • The bearing housings and journals are ‘8 point’ measured using precision digital micrometers capable of measuring to 3 decimal places to check for correct SKF fit tolerances.
  • The rotor is balanced to an enhanced G1.0 balance specification. (Better than a new motor)
  • All stators are stripped using a controlled pyrolysis (burn off) oven set to 370 °C to ensure the motor efficiency is not affected.
  • Lexseco Core loss testing is performed before and after stripping to prove motor efficiency is not affected.
  • Stator rewinds are carried out to full class ‘H’ specification (better than a new motor)
  • Genuine SKF bearings are fitted to SKF procedures using a degaussing and temperature controlled bearing heater.
  • The motor feet are checked for flatness.
  • The motor is run tested and vibration conformance is recorded and analysed against strict SKF specifications.
  • A compressive service report is compiled and shipped with the motor
  • All rewound motors are covered by a 2 year guarantee (Better than a new motor)
