TY - JOUR TI - Calculation methods for eddy current losses with the example of a permanent magnet excited synchronous machine inside the threshing cylinder of a combine harvester AU - Schuffenhauer, Uwe AU - Michalke, Norbert TI - Calculation methods for eddy current losses with the example of a permanent magnet excited synchronous machine inside the threshing cylinder of a combine harvester AB - Electrical drives become more and more interesting for many applications in mobile machines including farming equipment. In this paper, the electromagnetic design of a threshing cylin der for an electrical combine harvester with a function-fitted external rotor and an inner stator is shown. Special attention will be paid to the calculation of the eddy current losses within the magnets through different FEM methods. The influence on the losses of segmentation of magnets in tangential and axial directions is shown.
