title = "Torque-density improvement in brushless doubly-fed reluctance machines using additional stator winding",
abstract = "Brushless doubly-fed machine (BDFM) 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, BDFMs have inherently poor torque density because of under-utilized machine magnetics in terms of achievable peak air-gap flux density that drastically offsets all the benefits. This paper proposes to use an additional electrical port to better utilize the machine magnetics through interaction of multiple spatial airgap harmonics that lead to additional torque production. Using FEA, the performance of the proposed motor is analyzed and compared with that of a BDFM with two electrical ports to highlight the merits of the proposed design. With the addition and appropriate excitation of the extra stator winding, torque is improved by 26% as compared to a conventional BDFM.",
