Description

管状电机 技术领域
本发明涉及一种管状电机，特别是一种用于卷帘门升降的管状电机。
背景技术
管状电机主要应用在卷帘门的升降上，因此，当管状电机断电时要求管状电机能迅速停止运转以保证卷帘门的升降位置，这就需要管状电机具备良好的刹车性能。现有的管状电机均采用直接移动刹车组件的方式来控制刹车，这就造成了刹车组件和激磁线圈必须设置在管状电机的同一端，而造成了电机设置刹车组件和激磁线圈的该一端结构过于复杂，装配困难，同时也降低了刹车的可靠性。
 技术问题
本发明解决了现有技术所存在的电机设置刹车组件和激磁线圈的该一端结构过于复杂，装配困难，同时也降低了刹车的可靠性问题，提供了一种装配方便，刹车可靠的管状电机。
 技术解决方案
本发明的上述技术目的是通过以下技术方案解决的：它包括机壳，机壳内装配有定子，定子内设有转子，转子的转子轴两端与机壳形成旋转支撑并可在机壳内进行轴向移动，机壳内部的一端设有激磁线圈，该激磁线圈与电机同步通、断电，转子轴与激磁线圈相邻的一端固定有吸铁组件，转子轴对应于吸铁组件和转子铁心之间的部位套设有压缩弹簧；机壳内部另一端固定有静刹车盘，转子轴上与吸铁组件相对的另一端固定有与静刹车盘对应的动刹车盘；当激磁线圈与电机一并通电时，激磁线圈产生的磁力将吸铁组件吸合使转子克服压缩弹簧的阻力在机壳内向激磁线圈该侧移动，动刹车盘与静刹车盘脱开，电机正常运转；当激磁线圈与电机一并断电时，激磁线圈的磁力消失，在压缩弹簧的作用下转子在机壳内向设置静刹车盘的一端移动，动摩擦盘和静摩擦盘相互压紧阻止转子转动，电机迅速停止运转。本发明将激磁线圈、吸铁组件与静刹车盘、动刹车盘分别布置在机壳的两端内部，克服了电机一端结构过于复杂的问题，从而便于电机的装配，也提高了刹车的可靠性。当电机与激磁线圈一并通电时，激磁线圈得电产生磁场，与吸铁组件发生磁力作用并吸合，从而带动转子轴向激磁线圈一端轴向移动，动刹车盘与静刹车盘脱开，电机正常运转；当激磁线圈与电机一并断电时，激磁线圈的磁力消失，在压缩弹簧的作用下转子在机壳内向设置静刹车盘的一端移动，动摩擦盘和静摩擦盘相互压紧阻止转子转动，电机迅速停止运转。
作为优选，所述动刹车盘的外径和静刹车盘的外径均与机壳内壁的内径相配，从而可尽量加大动刹车盘和静刹车盘的直径及两者的接触面积，以增大两者的摩擦力，加强刹车效果。
 有益效果
因此，本发明具有装配方便，刹车可靠的特点。

当激磁线圈5与电机一并通电时，激磁线圈5产生的磁力将吸铁组件6吸合使转子克服压缩弹簧的阻力在机壳内向激磁线圈该侧移动，动刹车盘与静刹车盘脱开，电机正常运转；当激磁线圈与电机一并断电时，激磁线圈的磁力消失，在压缩弹簧的作用下转子在机壳内向设置静刹车盘的一端移动，动摩擦盘和静摩擦盘相互压紧阻止转子转动，电机迅速停止运转。
