Abstract :
A direct method of field orientation has been implemented that requires little knowledge of machine parameters and requires only readily measurable quantities. The system uses tapped stator windings to measure the air gap flux. The signals from the tapped windings are also used in a flux regulation loop. The ripples created in the tapped windings by the motion of the rotor slots through the flux provide speed information to the speed controller.<>
