Abstract: This paper presents a novel three-phase U-core stator
motor with the modular topology based on the conventional single-phase motor
to solve the problems of high torque ripple and non-self-starting ability,
which has the similar advanced performance as a two-phase motor. Basic
topology and torque analysis are discussed for the proposed three-phase
motor in terms of the single-phase modules. Finite-element method (FEM) is
carried out to compare and verify the competitive performance of the
proposed motor and the practicability of such modular design concept. The
dynamic starting performance in the proposed three-phase motor is finally
simulated by utilizing the Simulink models and compared to those of the
single-phase and two-phase models.
Keywords: Modular topology, PMSM, simulink models, three-phase U-core stator motor
