Hi all,
I am conducting some tests on a simulated physical model of a motor/drive axle system. The goal of the experimentation is to come up with some suggestions to reduce the peak magnitude at the resonant frequency by 30%.
Based on the analysis done, a few proposed changes are 1) increasing the motor resistance, 2) increasing the motor constant and 3) modifying the inertia of the flywheels that the axle is attached to.
I am having some difficulty in figuring out why these would lead to a reducing peak magnitude at the resonant frequency and I was wondering if anyone could help out.
For example, my understanding is that motor resistance has a direct correlation to motor efficiency- ie if I have a motor with a lower motor resistance my motor will be more efficient and thereby be able to supply more power. However what does this really have to do with the resonant frequency.
I would greatly appreciate if anyone could give me some tips on how those above listed factors are related to resonance/ resonant frequency.
Thanks for your time and I hope i have explained myself clearly enough.
