就算唔係mod過既motor
唔同廠商既Turn數同kv值都會有唔同
如果要咁樣對照的話,只可以搵同一間廠兩隻唔同Turn數既motor做比較
如kai0621師兄所講,Hobbywing有呢d對照表
但係唔代表其他廠商既motor都岩用作者: yokomo 時間: 2009-11-13 11:21
Actually, I got a Team Power 3700kv Brushless motor.... but don't know what is the suitable gear ratio.作者: Aurora 時間: 2009-11-13 11:54
這個很難有說, 每一間廠的T數對KV值都不一樣,比如說LRP的9.5T是3900多KV, 但Dualsky的7.5T才有這個值。 而且每間廠的摩打扭力/散熱/耗電/齒比都不一樣, 齒比搭激一點的, 要小心會燒, 都係自己慢慢試穩陳。作者: hardmankam 時間: 2009-11-13 12:09 9#yokomo
You can treat a 3700kv to be a 'typical' 10.5R motor. So gearing should be in the 5.2 to 6.5 range.
However, many factors will affect gearing: ESC, battery, car weight, size of course, outside temp. etc...
It is best to use a temperature gun and measure the motor's temp after a few laps. If temp between 140 to 160F (or 60 to 70C) then your gearing is good for that course.作者: yokomo 時間: 2009-11-13 13:40

3700kv @ 7.2V = 26640Rpm/7.2V
