Abstract

Permanent Magnet Linear Motors (PMLMs) are widely applied in xy-positioning stages such as laser cutters, pick & place systems or vision inspection devices.In this paper, a 2-D quasi-static coupled magnetic-thermal model based on the spectral element method which is used to model the temperature distribution in a synchronous linear motor due to ohmic and hysteresis losses. The magnetic and thermal field distributions are derived separately using the Galerkin formulation where Legendre-Gauss-Lobatto (LGL) polynomials are applied as basis functions. Coupling of the magnetic and thermal domain is performed by nodal calculation of the hysteresis losses using Steinmetz's equation.
