在EVM的说明里面写的很清楚啊。不知道你说的是什么。
A.3.1.3.2 Pole
The number entered into the Pole text field is used to calculate the RPM in the Display section, given by
the formula in Equation 1.
If motor speed (Hz) ≥ 2, motor speed (rpm) = (1 000 000 / electrical period [µs]) × 120/pole. Else, motor speed (rpm) =
motor speed (Hz) × 120/pole.
The default value of this control is 1.
