A method for dynamic modelling of induction
machine with a doubly slotted air gap is proposed and
implemented for the case of a cage induction motor. The
described method is easily extensible to wound rotor machines. A
numerical description of the air gap permeance is provided that
takes into account a slotted stator and rotor structure as well as
their mutual, time and space dependant positions as a function of
rotor rotation. The multiple coupled circuit model approach is
used with the modified winding function in order to calculate the
inductance of all motor windings. The developed model is general
in nature and could be used for the analysis of different dynamic
regimes of induction machine, particularly different combinations
of stator and rotor slot numbers. Model validation is provided by
stator current spectrum analysis of a standard four pole induction
motor with S=36 and R=32 slots. The experimental results
presented clearly support these findings.
