稀土永磁材料在无刷直流电动机中的前景

Rare Earth Permanent Magnet Material in the Prospects of a Brushless DC Motor

稀土永磁无刷直流电动机既有精确的控制特性,又能消除电刷和换向器的机械接触带来的负面因素,而且应用具有较高磁性的稀土永磁材料可减轻重量和简化电磁计算。

Rare earth permanent magnet brushless DC motors have precise control characteristics, but also toeliminate the negative factors brought about by the mechanical contact of the brushes and commutator, and the ap- plication of higher magnetic rare earth permanent magnet materials to reduce weight and simplify electromagnetic calculations.
