| 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. |

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

Please help me :) |
