I am driving a DC motor with H-Bridge Mosfet using PWM. The problem is I don't know exactly which frequency should I use.
1- Do the DC Motors have a very specific frequency for their best performance at all or they have a range of the frequencies they are able to work with?
2- What happen if I work with a DC Motor with Higher or Lower frequency that it can work with? Am I damaging that? (Because I have done that and with higher frequency my Motor make a strange noise like zzzz and with lower frequency it is shaking)
