RE: Rotor Beats

If you don't know why, then why worry about how

just kidding.

I think that maybe you are talking about the fact the motors will sometimes give a vibration which beats.

That can either be due to interaction of a harmonic of running speed with the 2*LF vibration, or else it can be due to pole-pass modulation which occurs when rotor bars are broken or when there is dynamic eccentricity. See a recent post entitled RBF.

I'm not sure if that's what you're after.  If you have specific additional questions please ask.

RE: Rotor Beats

Suggestion: Please, would you clarify nature of beats, i.e. electrical linked to torque, or mechanical linked to rotor vibration?
