Ns1-500 Stator Rotor Ns2=500 Figure P1.3 Cross-sectional view of de machine (a) Redraw and label clearly the magnetic circuit shown in the figure and clearly indicate the direction of flow of the flux. (b) It is required to operate this machine with an air-gap flux density of 1.8T. Calculate the current that should flow in the stator coils. (c) Calculate the self inductance of the stator coils.
