3 Phase Rotor / Stator Swapping ??? I have been toying around with the following idea : (specific application project) Normally a stator is the external housing of a motor and is fixed to a structure - the rotor is the shaft through the middle of this stator etc. and is rotating at ...x... RPM ! The application that I have been unable to find on the net is if I were to swop the rotor/stator around - i.e. the shaft (normally the rotating rotor) is static / standing still AND the stator (normally fixed and static) is now spinning at ...x...RPM ? Is there anyone that knows of such a design / motor ?
