Three-phase field excitation flux switching motor (FEFSM) with salient rotor structure has been introduced with their advantages of rotor easy temperature elimination and controllable FEC magnetic flux. Yet, the salient rotor structure is found to lead a longer magnetic flux path between stator and rotor parts, producing a weak flux linkage along with low torque performances. Hence, a new structure...
A flux switching machine (FSM) with a segmented rotor and non-overlap windings is an attractive alternative for driving high torque density applications. However, a rotor with segments makes the motor less robust as well as difficult to be assembled, whilst, FSMs with salient rotor and overlap windings inherit high copper losses and less efficiency due to high coil volume. In this paper, performance...
This paper presents the study of a C-core topology for direct-drive PM synchronous wind generators (PMSGs) with non-overlap iron-cored stator windings. Some of the most common challenges regarding wind energy converters are first considered, leading to the development of the C-core topology concept and the theory behind it. Results from the finite element (FE) simulations are presented and finally...
