Mathematical modeling of frequency-controlled electric drive with dual-winding induction machine considering spatial harmonics
Mathematical modeling of frequency-controlled dual-winding induction electric drives typically involves using mathematical circuit models to investigate transient and steady-state modes. Such models often disregard spatial harmonics. Spatial harmonics in machines refer to the harmonics of the distribution of the winding function within the machine stator slots. Mathematical models based on the method of finite element analysis are primarily used to study the influence of spatial harmonics on the stator current and electromagnetic torque of dual-winding machines.
