Abstract

LINEAR PARALLELEPIPEDIC ELECTRIC MACHINE: LOSSES IN THE MOVING PLATE

Pierre Kenfack*, Stève Ngoffe Perabi and Abraham Dandoussou

ABSTRACT

This paper details the calculation of losses in the flat moving plate (rotor) consisting of permanent magnets (NdFeB) between two fixed stators of a linear parallelepipedic electric machine. The resistivity of Neodymium-iron-boron (NdFeB) magnets is between 120 and 160*10-8 ?.m. The heat dissipation from the two stationary stators can cause a temperature rise that demagnetizes the highly temperature-sensitive NdFeB magnets. The heating of the NdFeB magnets reduces the remanent induction Br and therefore the tangential force. In addition, this heating can damage adhesives, resins or varnishes, which can cause permanent magnets to loosen. Eddy current losses in permanent magnets are created by the space and time harmonics of the armature reaction field, as well as by the permeance variations seen by the magnets (alternating teeth and slots); they cannot be neglected. The losses in the magnets (moving plate) of the linear parallelepipedic machine are determined by the finite element method using the ANSYS MAXWELL software.
