Dynamic reluctance mesh method (DRM) combines the advantages of finite-element method(FEM) and magnetic equivalent circuit method. The attractive advantages of this method include as follows: less mesh units compared with FEM; higher computational accuracy than traditional magnetic equivalent circuit method. This paper presents modeling and analysis of permanent magnet synchronous motor using DRM...
Induction heating is a process where a varying magnetic field is used to heat a conductor or workpiece. When a piece of metal or conductor is placed near a magnetic field created by energising a coil of wire, the magnetic field transfers energy into the conductor, thus heating it up. This paper presents three methods for modelling induction heaters at mains frequency. These models are known as the...
Existing circuit-field coupling schemes can deal with a single magnetic field model connected to an external circuit. However, modern electrical systems are a complex interconnection of multiple magnetic devices, which opens up the question of how to consider multiple interacting field models. In this paper, we propose a scheme based on the finite element and modified nodal analyses, to solve the...
The investigation on flux-switching permanent magnet (FSPM) machines in existing papers has been restricted to specific combination of stator and rotor pole numbers, viz. 12/10 stator/rotor poles. In this paper, the influence of stator and rotor pole numbers on the optimal parameters of the FSPM machines are investigated by the finite element analysis and the lumped parameter magnetic circuit model,...
The aim of this paper is to design a lightweight transverse flux permanent magnet (TFPM) machine for large scale direct-drive wind turbines. The requirements for suitable generator systems for wind turbines are discussed. Analytical modeling of TFPM machines is discussed by considering the machine parameters and the magnetic circuit. The proposed analytical model is verified by comparing it to results...
