Three Phase Induction Machine

Representation of Field

Objective:
	To present a rotating vector representation of a rotating field pattern.
Steps:
	For a 2-pole machine the field pattern, due to 3-phase stator currents, rotates as shown.

	This can be represented as a rotating vector.

	The length of the arrow can represent maximum flux density,

	or "total field" or flux across the air gap.
