電機是一種輸入電功率、輸出機械功率的原動機械。因此，我們關心的是它的轉矩、轉速，以及轉矩和轉速隨輸入電壓、電流、負載變化而變化的規律。據此，電機的運行特性可分為起動特性、工作特性、機械特性和調速特性。

討論各種電機的運行特性時，－般都從轉速公式、電動勢平衡方程式、轉矩公式和轉矩平衡方程式出發。

無刷直流電機的特性計算需要考慮電機的電磁特性和機械特性兩個方面。其中，電磁特性包括電機的電磁勢、電磁轉矩、電機的轉速和電流等，機械特性包括電機的負載特性、轉動慣量、轉矩常數等。下面介紹一些常用的無刷直流電機特性計算公式：

轉速計算公式：

N = K × （V - I × R） / Φ

其中，N為電機轉速，K為電機常數，V為電機電壓，I為電機電流，R為電機電阻，Φ為電機磁通量。

扭矩計算公式：

T = K × I × Φ

其中，T為電機輸出扭矩，K為電機常數，I為電機電流，Φ為電機磁通量。

功率計算公式：

P = T × N / 9550

其中，P為電機輸出功率，T為電機輸出扭矩，N為電機轉速。

效率計算公式：

η = Pout / Pin

其中，η為電機效率，Pout為電機輸出功率，Pin為電機輸入功率。

電機常數計算公式：

K = Φ / （I × N）

其中，K為電機常數，Φ為電機磁通量，I為電機電流，N為電機轉速。
