Analysis of the steady-state components in a balanced single-phase synchronous reluctance motor with a running capacitor

Steady State Analysis Of Single Phase IPM Motors By D-Q Harmonic Balance Method

“…Flux linkage in the field windings of the 1-Φ machine due to the permanent magnet in the rotor and which rotates in an unbalanced condition is modeled as [11]: The q-d axis currents of the magnet torque can be derived once the IPM machine operates as a generator and the field winding is bridged, the established torque then became the braking torque produced by the presence of rotor magnets. Because of this, equations ( 14) and (15) were substituted in the q-d axis voltage equations ( 1) and ( 2) while setting the voltages to zero as the machine operates at a constant speed. The d-q axis magnet flux linkage equations, therefore, emerge as stated in equations ( 16) and ( 17) below [12].…”

“…Applying phasor analysis to the electromagnetic torque equation (21) in a decoupled arrangement by replacing equation (10 -13) in equations(1 -9) also in decoupled form and other physical variables as expressed in equation ( 31) and (32) and solving algebraically, the harmonic balance torque equations expression in the parts would therefore be derived as illustrated below [14,15].…”

“…Further, when the frequency is kept constant, Equation ( 2) is satisfied at certain value of slip. Varying of the slip (S) leads to variation of the stator currents while for certain values of the slip specifically S = S sym , the stator currents will equal each other [21]. The phase-angle between the phase currents that required establishing the balance can be obtained by using shifting capacitor.…”
