缝纫机电机的电刷结构
本技术涉及缝纫机领域,尤其是一种缝纫机电机的电刷结构。
技术介绍
直流电机常用电刷接电;中国专利申请号:CN201310053581.0的专利技术公开了一种直流电机电刷,包括:电化石墨、电刷压板、电刷辫子和与电刷辫子的一端连接的刷辫端子;其特点是,电化石墨为浸渍电化石墨,电刷压板安装在浸渍电化石墨的顶面上;电机电刷还包括:绝缘变色导向套管,从浸渍电化石墨内通过电刷压板向上延伸出,电刷辫子的另一端穿过绝缘变色导向套管并通过电刷压板伸入浸渍电化石墨内;以及V型绝缘垫块,安装在电刷压板的顶面上。缝纫机电机为了减轻重量,电机壳体和端盖常采用塑料制作;传统的直流电机的电刷用于缝纫机电机中存在安装不够稳固且壳体易损坏的不足;因此,设计一种安装稳固且壳体不易损坏的缝纫机电机的电刷结构,成为亟待解决的问题。
