Parameter estimation and performance evaluation of a Linear Permanent Magnet Synchronous Motor prototype

This paper deals with theoretical evaluation and practical determination of the parameters of a 3-phase, 4 pole, 320 W, 5 m/s linear permanent magnet synchronous motor (LPMSM). The motor had been designed in the laboratory and fabricated at the works of local manufacturer. The parameters have been estimated by analytical calculations and validated using standard FEM packages. The practically determined machine parameters are found to be in excellent agreement with theoretically estimated values. This fact highlights the accuracy of the design, precision of fabrication and the correctness of the testing exercise. The field weakening capability of the LPMSM motor has also been investigated.
