VAriable Frequency Drives

[mastertech]

Hello,

I want to change the speed of a motor with a Variable Frequency Drive. Does someone know what a motor has to have in order to be suitable to install a VFD? In which motors can I install a VFD and what special features does it has to have????

Thank you. I am mechanical
