The field analysis using cylindrical coordinates for sleeve rotor induction machine is discussed.
The magnetic field equations are carried out applying a simple model. The electric loading of
rotor and the air gap flux density are calculated and plotted as a function of the machine speed.
The effect of the sleeve material is taken into consideration.
The stator phase induced voltage is determined, and the air gap impedance is obtained in terms of
machine design geometry. The individual sleeve rotor resistance, leakage reactance, and stator to
rotor mutual reactance expressions are simplified for a minimum calculation effort.
