Flux-Switching machines (FSM) have been gaining attention during the last decade. Their electromagnetic behavior has been extensively studied for various topologies, i.e. U-core and E-core, simple (wound field or PM) and hybrid excitations FSM machines. Even though noise and vibrations of electromagnetic origins can be important drawbacks, depending on the application, only few studies are analyzing...
This paper describes the modeling of a permanent magnet synchronous machine (PMSM) by using lumped models (LMs). Designing electrical machines necessarily involves several fields of physics, such as electromagnetics, thermics, mechanics, and acoustics. Magnetic, electrical, electronic, and thermal parts are represented by LMs, whereas vibro-acoustic and mechanical parts are represented by analytical...
Cogging torque is one of the important issues for permanent magnet machines. Due to the interaction between the permanent magnets and slotted armature lamination, there exists cogging torque in slotted permanent magnet machines, which may cause noise and vibration. To reduce the cogging torque, the expression of the cogging torque was studied based on the Fourier analysis in this paper. Based on the...
