Squirrel cage induction motor cast rotor defect detection with magnetic field analysis

  title={Squirrel cage induction motor cast rotor defect detection with magnetic field analysis},
  author={Scott W. Clark and Daniel Stevens},
  journal={2015 18th International Conference on Electrical Machines and Systems (ICEMS)},
Testing of squirrel cage induction motor rotors for rotor cage defects while the motor is in an unassembled state is an important quality control check in the manufacturing and repair process. A new testing method using magnetic field analysis capable of identifying defects in squirrel cage inductor motor rotors is described. The rotor field analysis, RFA, testing technique is explained with finite element analysis used to demonstrate the magnetic field detection process. A guideline for test… CONTINUE READING
