Calculating RPM from BEMF frequency of BLDC motor

(1/2) > >>

Tomsik:
Hello,
I'm a beginner in driving motors and I need to calculate RPM (rotation speed) from frequency BEMF signal on 1-phase of a 12N14P motor when it'is possible.

I measured 1.6kHz repeating signal (sinus) at 1-phase of BLDC motor.
Can I calculate RPM from these parameters?

Thank you

You would need to know the number of poles in the motor to derive RPM from that figure.

Tomsik:
According to the shared thread I think I have 12 poles of stator, it means 6 pair poles.

Tomsik:
Please help me  :)
