电机有两大类:交流电机、直流电机。交流电机中用得多的是异步电机(感应电机),转别是鼠笼式异步电机。现在伊诗图电气Eastour给大家介绍直流电机、交流电机调速方法。
直流电机调速方法:
直流电机是指将直流电送到直流电机,把直流电机的电能转换成机械能。这里首先要介绍如何将市电的交流电转换成需要的直流电。六十年代以前采用的是发电机--电机系统(f-d),这种方法只有在电机由专用的发电机供电时才有可能。另一种是可控硅--电机系统(scr-d)。
直流电机的调速还比较方便,可以通过调节电枢供电电压,电枢中串联电阻,激磁回路串联电阻来实现。
可见直流电机调速有三种方法,而且调节电枢供电电压的方法容易实现平滑、无级、宽范围、低损耗的要求。直流电动机电磁转矩中的两个可控参量和是互相独立的,可以非常方便地分别调节,这种机理使直流电动机具有良好的转矩控制特性,从而有优良的转速调节性能。
尽管直流电机调速就其性能而言,可以相当满意,但因其结构夏杂,惯量大,维护麻烦,不适宜在恶劣环境中运行,不易实现大容量化、高压化、高速化,而且价格昂贵。

蜗轮减速机自锁功能的应用
实际上蜗轮减速机就是蜗轮蜗杆减速器,因为蜗轮与蜗杆在减速器的应用当中都是成对出现的。减速器中有一个蜗杆就一定会有一个蜗轮,因此蜗轮减速器只是人们对蜗轮蜗杆减速器的一种口语化叫法。但通常大家更喜欢把蜗轮蜗杆减速器称为蜗轮蜗杆减速机。或者说蜗轮蜗杆减速机是更通用的一种叫法。下面你可以点击查看.
简单介绍一下蜗轮及蜗杆机构的特点
可以得到很大的传动比,比交错轴斜齿轮机构紧凑
两轮啮合齿面间为线接触,其承载能力大大高于交错轴斜齿轮机构
蜗杆传动相当于螺旋传动,为多齿啮合传动,故传动平稳、噪音很小

电机保养维修中心电机保养流程:清洗定转子--更换碳刷或其他零部件--真空F级压力浸漆--烘干--校动平衡。使用环境应经常保持干燥,电动机表面应保持清洁,进风口不应受尘土、纤维等阻碍。当电动机的热保护连续发生动作时,应查明故障来自电动机还是超负荷或保护装置整定值太低,消除故障后,方可投入运行。应保证电动机在运行过程中良好的润滑。一般的电动机运行5小时左右,即应补充或更换润滑脂,运行中发现轴承过热或润滑变质时,液压及时换润滑脂。
