有刷电机爆转子你见过吗？
话不多说先上图，这个是粗齿锯EV2履带车上的390有刷马达，转子线圈被甩了飞出来了，彻底废了。。。http://image.rcfans.com/pic/20220828/1661698096397426_844.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
无奈花了34元(含运费)买了个原装电机，为何买原装电机？我也不想的，奈何铜齿轮拆不下来，齿轮连电机轴切下来，用螺丝刀想把轴敲下来，结果把钢材质的螺丝刀干断了。。。无语

分析了下原因，马达散热环境太差，持续高温运转导致线圈发热膨胀甩出，之前论坛有模友提过这个发热问题，所以趁这次机会加装了马达散热风扇，波箱开洞，风扇尺寸刚好，基本完美安装

安装好了，通电，运转正常

尾灯是之前就改装过的，依旧骚气https://app.rcfans.com/public/emotion/face_wangchai.png

转向260马达感觉也快不行了，艹https://app.rcfans.com/public/emotion/face_055.png，顺便拆开保养了下，换向器和碳刷磨损严重，运转时灵时不灵的，不想再花钱了，独家秘法处理了下，完美修复，应该能撑一段时间了！
铜线圈还会发热膨胀？ 蔷薇蔷薇 发表于 2022-09-02 10:57
铜线圈还会发热膨胀？
线圈肯定发热呀，热胀冷缩，再加上高转速，离心力，甩爆也不是没有可能 说的有道理
