摘要
非晶合金材料电磁性能优异,应用于电机领域能显著降低电机铁心损耗,提高电机效率。针对非晶合金材料的特点,基于永磁电机基本设计理论,推导了非晶合金电机铜耗与铁心损耗的解析表达式。基于非晶合金永磁电机损耗的解析表达式对非晶合金永磁电机裂比(定子内外径之比)、磁密比值(气隙磁密与铁心磁密之比)的设计进行了研究,得出了非晶合金永磁电机裂比、磁密比值的设计规律。在对非晶合金永磁电机设计规律研究的基础上完成了一台非晶合金永磁电机的设计并进行了试验。所做的研究对非晶合金电机的设计及优化具有一定的参考价值。
Due to its excellent magnetic performance, amorphous metal offers the potential of reducing the core loss of motors dramatically and improve the motor efficiency. According to the characteristics of amorphous alloy materials, based on the basic design theory of permanent magnet motor, the analytical expression of copper loss and core loss was derived. Through the expression of loss, several key design variables were emphasized： the inner-to- external diameter, the flux density, that assumed a decisive role in the permanent magnet motor. The design rules of amorphous alloy motor were summarized. On the basis of design rules, an amorphous alloy permanent magnet motor was designed and tested. The study had certain reference value for design and optimization of amorphous alloy motor.
