二、无刷电机与有刷电机性能之比
1、摩擦大,损耗大
有些朋友在用有刷电机的时候常碰到这个问题,那就是使用电机一段时间以后,需要打开电机来清理电机的碳刷,费时费力,维护强度不亚于来一次家庭大扫除。
2、发热大,寿命短
由于有刷电机的结构原因,电刷和换向器的接触电阻很大,造成电机整体电阻较大,容易发热,而永磁体是热敏元件,如果温度太高的话,磁钢是会退磁的,使电机性能下降,影响有刷电机的寿命。
3、效率低,输出功率小
上面说到的有刷电机发热问题,很大程度是因为电流做功在电机内部电阻上了,所以电能有很大程度转化为了热能,所以有刷电机的输出功率不大,效率也不高。
通过比较不难发现,相对于有刷电机,无刷电机的优势在哪里了。但是万事都不是的,有刷电机低速扭力性能优异、转矩大等性能特点是无刷电机不可替代的。不过,就无刷电机的使用方便性来看,随着无刷控制器的成本下降趋势和无刷技术的发展与市场竞争,无刷动力系统正在高速的发展与普及阶段,这也极大促进了国内无刷电机的发展。

行星减速机用途广泛,一般适用于工业行业。又可作为配套部件用于起重、挖掘、运输、建筑等行业。其性能可与其它军品级减速机产品相媲美,却有着工业级产品的价格,行星减速机广泛在华东地区、华北地区被应用于广泛的工业场合。
行星减速机厂家对行星减速机的工作原理和日后保养的介绍
行星减速机
一、行星减速机厂家对行星减速机的工作原理介绍
由一个内齿环(A)紧密结合於齿箱壳体上,环齿中心有一个自外部动力所驱动之太阳齿轮(B),介於两者之间有一组由三颗齿轮等分组合於托盘上之行星齿轮组(C)该组行星齿轮依靠著出力轴、内齿环及太阳齿支撑浮游於期间;行星减速机当入力侧动力驱动太阳齿时,可带动行星齿轮自转,并依循著内齿环之轨迹沿著中心公转,游星之旋转带动连结於托盘之出力轴输出动力。

不允许用榔头敲击轴承,注意轴承不要掉在地上(或者是类似的处理不当)。安装前也应对轴和轴承座的状况进行检查,即使是微小的磨损也会导致配合不良,从而引起轴承的早期失效。对轮毂轴承单元,不要企图拆开轮毂轴承或调整轮毂单元的密封圈,否则会使密封圈受损导致水或灰尘的进入。甚至密封圈和内圈的滚道都受到损坏,造成轴承的失效。装有ABS装置轴承的密封圈内有一个磁性推力环,这种推力环不能受到碰撞、冲击或者与其他的磁场相碰撞。
