TITLE: "Modeling of Rotor Flux-barriers in a Brushless Doubly-fed Reluctance Machine"

WHEN: March 8, 3 - 3:50 pm via ZOOM (please contact rsmth@illinois for meeting specifics)

ABSTRACT: A brushless doubly-fed reluctance machine (BDFRM) is an attractive option for megawatt-scale wind-energy generation and electrified transportation due to its partially-rated power converter, reduced maintenance, and absence of permanent magnets. However, BDFRMs have inherently poor torque density and high torque-ripple because of using a sub-optimal rotor. Since the flux-modulation in a BDFRM is carried out by the rotor, the rotor structure plays an important role in torque production. This presentation describes an analytical model to compute the air-gap flux density and torque characteristics, with the aim of modeling the effect of the flux-barriers on the mean and ripple torque. Through the analytical and finite element analysis, it is verified that the position of the flux-barrier ends highly influences the torque waveform, and thus cannot be arbitrarily designed.
