建议多看贴。
kv值不同。代表在同一电压下的转速不同。高kv带小浆，扭力小，速度快。
低kv带大浆，扭力大，速度慢，
楼上说的 对&&LZ还有什么不明白的话 我可以帮助你 可以在论坛提问
多潜水看帖子就明白了~~
kv1000跟kv930，带同尺寸桨，商家给的静推力是一样的~~
我也不明白，但不知道飞起来差别大不大~

请问fxadm(自由沸点）：电机的kv值，除了与线径有关外，和电机转子的槽数、磁铁的级数多少有什么关系？

请问fxadm(自由沸点）：电机的kv值，除了与线径有关外，和电机转子的槽数、磁铁的级数多少有什么关系？
这里的kv不是电压单位。这种电机输入电压每提高1v,电机空载转速提高的量，称为KV值。230kv即电机空载情况下，1V电压，转速为每分钟230转，2V电压每分钟460转相同型号电机，低KV值比高KV值的提供的推力大。但是，KV值的需要配大桨，很多机型都不适合，会造成严重的反扭现象。 低KV值的电机虽然推力大，但是速度慢。很多人不理解了，为什么力量大速度反而慢？ 我打个比方，汽车挂一档时，力量最大，但是速度最慢，挂五档时，力量最小，速度最快。 相同型号电机，KV值高的比KV值低的速度快。 以下是配桨参考：飞翼，后推、腰推战斗机，纸飞机，飘飘机等，用高KV配小桨。 练习机，微风，赛斯纳，战斗机等，用KV1500左右的电机，3D机用低KV配大桨。 希望新朋友不要盲目选择电机，选择最适合你的机型的电机才是最好
明白了吗？
