The IM I have is a "wound rotor IM", whose rotor terminals are accessible (just like 3 stator terminals, so I have 6 terminals)...
Suppose I use another motor to drive this wound rotor IM rotating and meantime feed three ROTOR terminals by 3ph sinusoidal voltages(synchronous w. rotor position), and leave the three STATOR terminals OPEN. Then, what the ph-ph stator voltage would be? Anything there? I know they won't be synchronous w. rotor voltage, but are they gonna be 3ph sinusoidal as well??
