Given:
To describe the magnetic field set up in the air gap of a four-pole three-phase induction motor by the currents in the stator windings is shown as:
To give an equation for the field intensity as a function of angular position around the gap and time, defining the terms in your equation is shown as:
a)The stator windings contains four magnetic poles. This spaced 90o in alternating order. The point towards north poles and then points opposite to the south poles because the magnetic field set up in the air gap of a four-pole three-phase induction motor by the currents.
