Induction heating is widely used in Industry, it’s meaningful to control the process of heating accurately. In the heating process, electromagnetic field and Thermal field are strongly coupled. Through the comparison of two-way coupled and single-way coupled, this paper verified the importance of multiphysics simulation in heating process by simulation of the cycle induction heater.
Because of the flexibility and clear physical concept, magnetic circuit calculation method (MCCM) is preferred during the early stage of the electromagnetic design of generators and motors. Based on the analysis of magnetic field distribution in halbach magnetized permanent magnet generator (HMPMG) by finite element method (FEM), this paper proposes a distributed magnetic circuit calculation (DMCC) for HMPMG. Because of the low permeability of permanent magnet (PM) material, the DMCC for HMPMG is quite different from that for electrical excitation generator. By dividing half-pole generator model into sub-sections along radial and circumferential direction with circumferential equi-interval nodes in air gap, the DMCC for HMPMG employs iteration to calculate magnetic flux density on air gap nodes. In the end, the validity and accuracy of DMCC are proved by FEM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
