| Abstract: |
| An approach of on-line condition-monitoring and mixed fault diagnosis for squirrel cage induction motors is introduced.It is based on the spectrum analysis of average instantaneous power,which requires no stator or rotor parameters and has the ability to separate mixed rotor faults.Theoretical analysis and experimental results demonstrate its effectiveness. |
| Key words: squirrel cage induction motor,fault,on-line monitoring,diagnosis,spectrum analysis |
