T SREEJITH KAILAS Edited By Sarath S Nair www.technologyfuturae.com MODELLING AND ANALYSIS OF A TWO PHASE INDUCTION MACHINE WITH NON-ORTHOGONAL STATOR WINDINGS
Introduction Starting torque is produced by designing the stator windings to be electrically different. Unsymmetrical 2-phase IM is designed to operate from a single- phase source Stationary reference frame is used in order to obtain voltage equations with constant coefficients. Rating of two phase induction machine is usually low. www.technologyfuturae.com
V QS,V DS =QS and DS-axis stator voltages Rm,Xm and Ra,Xsa-QS and DS-axis resistance and leakage inductance Rotor voltages are set to zero(because of squirrel-cage rotors) Voltage and flux equations 4 V DS =R a *i DS +(P/ ω b * ψ DS ) ……(2) V QS =R m *i QS + (P/ ω b * ψ QS ) ……(1) 0=(R r *i QR )-1/k* ( ω r / ω b )* ψ DR +(P/ ω b )* ψ QR …….(3) 0=(K ^2 *Rr*i DR )-k* ( ω r / ω b )* ψ QR +(P/ ω b )* ψ DR.....(4) www.technologyfuturae.com
