“…V os3 is updated twice every three spinning cycles, and will settle after V os1 and V os2 become sufficiently small. From equations (5) and (6) it should be noted that the contribution of V os1 and V os2 in the V os3 error signal appears with alternating polarity, and so V os3 will, on average, remain stable until the other two loops settle. At steady state, the residual offset V os1-3 will be limited to ± 1 LSB.…”

“…Comparing to studies on induction motors, faults detection by means of magnetic flux (internal or external) in synchronous machines have been slightly addressed in the literature. Faults evaluation method using flux measurements in the air gap have been discussed since 1970 [15] and interesting researches [16]- [18] and commercial equipments have been developed in the last few years [19], [20]. Another approach (used by a Canadian company called Iris Power [21]) is the installation of coil sensor in the motor or generator air gap region for monitoring flux values (or induction) produced by each poles.…”
