Brushless motor speed how to calculate?

If you want to test the speed of the brushless motor speed: there are 2 ways:
1 available tachometer direct test
2 the frequency of back EMF waveform can be calculated by using oscilloscope. Frequency / pole *60 is the speed per minute.
If the write speed closed loop control procedures, this is more complex. Divided into acceleration / deceleration / uniform three cases to write.
Generally for the continuous exchange of 12 phase /2 is a lap time (in the three-phase six polar uniform as an example).
