Calculation of temperature in the permanent magnet tubular linear motor

Abstract

The calculation results for the thermal field of the permanent magnet tubular linear motor (PMTLM) have been presented in the paper. For the analysis of heating, four different mathematical field models have been created. Each of them uses the finite element method (FEM). In the most simplify model only the standard convective heat transfer coefficient has been implemented. In the most sophisticated model, thermal radiation, convective heat transfer and dependence of the coil resistance vs. temperature have been included. The numerical models have been verified experimentally.
