Description

一种电机结构 技术领域
本发明涉及电机设备技术领域,具体是指一种电机结构。
背景技术
电机,俗称“马达”,是指依据电磁感应定律实现电能、机械能转换或传递的一种电磁装置。它主要是由定子、转子、机座及附件组成,定子是发电机和电动机等电机的重要组成部分。定子由电机壳或定子铁芯固定件、定子铁芯、电机绕组组成。转子由转子和电机传动轴、轴承等组成。定子铁芯的主要作用是通电后产生旋转磁场或是通过转子的转动产生的旋转磁场在绕组中产生感应电流,而转子的主要作用是在定子铁芯的旋转磁场中产生转矩或是通过转动产生旋转磁场,它的主要作用是在电能与机械能之间互换。
当电机运行时,在它的内部空间,以及电机绕组与铁芯所占的空间区域,存在着电磁场。而电机的性能,正是由电磁场在不同的媒质中的分布,变化,以及和电机绕组电流的互相作用决定的。现代科学已经证明,电机运行时内部是三维的电磁场,而现有的电机只有定子的内圆周面和转子的外圆周面交互做功,电机绕组两端还穿出定子铁芯裸露在外,仅利用了电机的部分电磁场。
综上所述,现有的电机存在浪费电磁铜线,铜损耗高,单交互面做功转矩小、发电量小,且电机还会产生局部过热,电机效率低,减少电机的使用寿命,因此需要进行改进。
