Any Ac 3 phase motor driven with a VFD Drive produces Rotor Voltage,

Perthitic ? New one on me! , is it as bad as Covid?
An AC induction motor does not produce any real voltage in the rotor shorted turns it is extremely small, there is a very high current flow however in the the single turns of a squirrel cage rotor which produce fractions of a volt.
