END COMPONENT OF STATOR LEAKAGE REACTANCE OF SQUIRREL CAGE INDUCTION MOTORS: Part 1. General analysis

The leakage reactance end component is calculated by considering the net flux linking the stator end winding when both stator and rotor are excited with currents so that the net flux density in the airgap is zero. The stator and rotor end windings are assumed to consist of coils that close through the airgap by means of fictitious filaments and thus their respective current distributions are represented by systems of closed currents. Iron boundaries other than the end plate are neglected and the end plate is considered to be unsaturated and also a magnetic mirror, i.e. μ=∞, ό=0.
