This paper addresses the analysis of the main thermal phenomena in brushless permanent magnet machines, such as demagnetization of the magnets due to the h eat created by losses. Several methods are investigated to mitigate complex loss components; i.e., magnet losses and AC copper losses. The efficiency of the cooling system, with natural or forced convection, is also presented.

Abstract
This paper addresses the analysis of the main thermal phenomena in brushless permanent magnet machines, such as demagnetization of the magnets due to the h eat created by losses. Several methods are investigated to mitigate complex loss components; i.e., magnet losses and AC copper losses. The efficiency of the cooling system, with natural or forced convection, is also presented.File in questo prodotto:
