RCFans论坛有刷电机是真不能随便超压

有刷正常的，换无刷会好一点

我感觉是电机问题，我3S用过15T的红蜘蛛，发热问题不用过多考虑，加个散热片就行，这个21T，按说该更耐压才对

谢谢敏锐的大佬们，今天拆了一下，固定铝合金电机座的两颗螺丝已经松了，而且高温变色，渗碳底盘没有烫坏，如果是原厂底盘估计会变形，电机拆解后发现果然是短路了，里面一堆焦炭味儿，电机后盖的两颗螺丝也松了，轻轻一拿就掉了，另外说一句这电机真不行，动平衡太拉了，一根轴线上糊了两大块鼻屎一样的配重泥，三槽绕线肉眼可见的不均匀

所有刷電機，都不建議用大c(大過30c)的鋰電，超容易燒摩打。高轉，電火花會燒熔碳刷及communtator 整流子。我小孩的時候， 540 電機用兩排7.2x2=14.4v NiCd玩，田宮機械電調，一樣沒事。雖然電壓大，但電池能提供的電流遠不及鋰電，所以沒燒電機。

雪豹，不如黑皮好用，还贵。。。发热厉害

同价位我选红蜘蛛，15T用3S随便干，压个小风扇温度完全可控

正常，2s田宫白皮玩一会也非常热

ski 发表于 23-6-11 07:34:18

我3s白皮猪还行但是那样子玩的时间不长就换无刷了时间长了不知道会咋样

Zealot233 发表于 23-6-19 09:44:48

我也和楼主差不多的问题，总之是不会再买雪豹了，发热太严重，固定的螺丝第一次玩就掉了，各种塑料变形，而且我还是2s，还是换了个550电机爽玩
