一种新型的换向器
本技术涉及换向器,尤其是涉及一种电机用的新型的换向器。
技术介绍
换向器是直流电机和交流整流子电动机电枢的一个重要部件。电机转动时起换向作用,是直流电机、交流串激电动机上作为电流换向,为了能够让电动机持续转动下去的一个部件。为了节省定位套管,使换向器安装方便、焊线牢固,中国专利CN204441680U公开了一种玻璃升降电机换向器,包括换向基体和换向铜片,换向铜片包括顶部带弯钩的主片体和上下两只固定脚,上下两只固定脚植入换向基体内与换向基体牢固结合,换向基体的上端面向上高高隆起形成隔离锥台,弯钩的背面由换向基体进行抵靠,主片体的中间沿主片体高度方向设有上下三个镂空型腔,最上和最下的镂空型腔分别与上下固定脚对准,镂空型腔设有左右开口从主片体的左右侧面往外进行贯穿,设有内侧开口从主片体的内侧面往外进行贯穿,最上和最下镂空型腔的内侧开口还将上下固定脚从中间进行贯穿,镂空型腔内填充电木粉材料与换向基体牢固结合。然而,上述换向器的弯钩背面由换向基体进行抵靠,这种结构会减小弯钩形变的空间,导致弯钩的形变得 ...
