Abstract
Commutation time of inverter fed synchronous motors is commonly expressed in terms of the commutation reactance Xc. A precise method of calculation is desirable especially for solid salient pole motors. A magnetic circuit method is used to model a machine cross section which is coupled to the stator windings making possible a direct coupling of the magnetic circuit with the inverter.
Commutation is effectively a line-to-line short circuit superimposed on a load condition and initial studies have been made on a line-to-line short circuit without rotor motion.
Calculated commutation on load agrees well with test results.
