Abstract
The stator core loss and eddy current loss was investigated in permanent magnet for the transverse flux permanent magnet linear motor (PMLM). Firstly, the stator core loss was investigated in the three-dimensional magnetic field, and the no-load three-dimensional field map and each point of the magnetic density waveform changes were provided, and the influence of the speed, current and the lagging/leading current control on the stator core loss were discussed. Secondly, The 3D eddy current field mathematical model of transverse flux PMLM was developed, and the eddy current loss was caculated in permanent magnet of the transverse flux PMLM in the mode of no-load and load. Finally, the test platform of core loss in prototype was developed. In order to verify the accuracy of calculation, the core loss measurement is designed and the comparison results are analyzed.
