Magnetic Field Analysis of a Brushless DC Motor Comparing Ferrite and NdFeB Magnets on Rotor

摘要：

This paper presents comparisons between threephase permanent-magnet motor with ferrite magnets on rotor and other with NdFeB (Bonded). Related to this replacement, the advantages and disadvantages are quoted. The analysis of magnetic field is made through the Finite Element Method. The used machine has nonsinusoidal flux. Its application main is in hermetic compressor household refrigeration systems. Also, the geometric and magnetic characteristics are presented.

关键词： Electrical machines brushless DC motor finite element analysis.
