A method for dynamic simulation and detection of dynamic air-gap eccentricity in synchronous machines Conference Paper uri icon

abstract

  • This paper presents the performance of salient pole synchronous machines with eccentric rotors. Relationships between stator current induced harmonics and dynamic eccentricity are investigated. The winding function theory accounting for all space harmonics in electric machines and presented by earlier researchers has been modified to adopt non-symmetric air-gap for the calculation of machine winding inductances. In addition, the winding inductances have been computed by finite element method to support those calculated by the modified winding function approach (MWFA). Magnetic coupled circuits approach has been utilized for simulating rotor and stator currents. The simulation findings are in close agreement with experimental results.
