Do you mean you excite one phase single-phase, using a capacitor to the 
third terminal for capacitive starting?  This is an interesting concept. 
  Normally when a three-phase motor is single-phased it quickly 
overheats and burns up.  Of course you have no mechanical load on it, 
but I have seen three-phase motors overheat and fail with little load on 
them.  Because the excited winding heats up eight times faster than 
normal, normal overload protection is ineffective.
