A new hybrid-excited flux-switching machine with excitation coils in stator slots

摘要

This paper presents a new topology of Hybrid Excited Flux-Switching Machine (HE FSM) with excitation coils located in stator slots (or inner DC windings). After describing the three phase structure to be investigated, the working principle is discussed and main electromagnetic performances are simulated by Finite Element (FE) Analysis. It is demonstrated that the air-gap field can be easily controlled which is interesting for variable-speed applications. Finally, a prototype having 12 stator poles and different rotor teeth number (10 or 14) was built. Experiments were performed validating FE simulations and the operation principle.
