標題: 摩打 T 數及 kV 之關係
喺 RC EVO 成日見到用幾多T 或者幾多 kV 形容摩打速度, 請問有無 c hing 知道佢地嘅關係呢?
好想知呀, 有無公式可以轉換呢?

No formula.  Different factory is different.  Normally lower T, higher kV.

Different size motor (540, 380, 370 etc) also different.  

T-rating seems like an old fashion brushed motor definition that is now used in new 540 brushless definition.  But maybe a better way to look at motor is to look at,
a) KV
b) power rating (Watts can handle) (volts x current)
c) max current (continous current and instantaneous "burst" current)
d) weight of motor

Typically, these are basic items for use when working with other RC models such as planes and boats.

Below are examples of Hobbywing series:-

Motor Size        Turn             KV (rpm/volt)
540        13.5        2500
540        10.5        3200
540        8.5        4000
540        6.5        5200
540        5.5        6000
540        4.5        7300
540        3.5        9100
