电动车电机2000w要多大电流
2000w电机9.09a限流额定功率2000w的电器，电流是9.09安。我居民最常用的标准电压的有效电压值为220V,根据功率(P)=额定电压(U)*电流(I),可以推导出：电流(I)=功率(P)/额定电压(U)。也就是2普通三拉二是80 不过锂电池最好是控器的2倍会好点电流乘电压等于功率，你这个算个大概，2000÷72,大约等于28安的电流。起步或者猛加速的时候电流会加大翻倍以前拿200a的*过没几天就退磁没力了。你看你电机能吃下多少安相电流，,然后看控器需要多少母线电流能够满足控器输出这么多相电流，这种不好说的，一般2000瓦都用像远驱330这种控，远驱330全开是170母330相我是401S拉2000电，100a电流，起步boost120a,能到103 全顺2000wp吃150安没问题

启动电流看控器的输出电流和电门给多大的信号，如果控器直接输出最高电压，启动电流在50A以上。电池用几安合适你好，启动电流不是这样计算的，启动电流看控器的输出电流和电门给多大的信号，如果控器直接2000w的电器，电流是9.091安。根据瓦特定律P=UI可以求出：2000W的功率电流有效值I=P/U=2000W/220V≈9.091A。2、你现在只有8.5A则P=UI=220V*8.5A=
