Lumped-Parameter Network Thermal Analysis of Permanent Magnet Synchronous Motor

Abstract

This paper develops a model based on an original lumped-parameter network configuration for the thermal transient analysis of a permanent magnet synchronous motor (PMSM). The specific PMSM was designed and optimized for a demanding aerospace application. The validity of the proposed lumped-parameter model is verified by measurements carried out in a thermal chamber.

3-D FEM and Lumped-Parameter Network Transient Thermal Analysis of Induction and Permanent Magnet Motors for Aerospace Applications

“…Under the extreme mode of operation, torque and rotating speed are equal to 6.0 m N ⋅ and 6,000 rpm respectively. High temperature, samarium cobalt permanent magnets and non-overlapping, alternate-teethwound, fractional slot concentrated winding configuration were used [8]- [11]. Induction Motor.…”

“…The specific lumped-parameter networks were implemented using Matlab and the SimPowerSystems library of Simulink [8]. The values of the parameters of the elements of the two models were determined by analytical expressions taking into consideration the geometric and operational characteristics of the IM and PMM.…”

“…The conventional approach for electric machine thermal analysis is based on lumped-parameter networks [8]. The popularity of the specific method stems from the fact that it is simple, easily applicable and computationally cheap.…”

An Improved LPTN Method for Determining the Maximum Winding Temperature of a U-Core Motor

“…After that, many researchers followed up and built various thermal networks. For example, Yabiku et al built a 9-node network for one linear motor, Rostami et al built a 13-node network for one axial flux permanent magnet machine [14][15][16][17], and Aldo Boglietti et al established four different orders of LPTN to study the effect of order on temperature prediction [18]. Moreover, Mohamed et al built a 3D LPTN to describe the thermal behavior of a YASA motor [19].…”
