Herein lies the problem of integral windup (also referred to as reset windup or integral saturation). It is a problem that has been around for decades and was solved long ago. We discuss why it occurs and how to prevent it to help those who choose to write their own control algorithm.
AC Windings Ac windings are generally of a 3-phase kind because of the inherent advantages of a 3-phase machine. The armature coils must be connected to yield balanced (equal in magnitude and successive phase difference of 2r/3 rad) 3-phase emfs. Application of Fractional Slot-Concentrated Windings to Synchronous ... winding machines, the average end turn length is a reciprocal function of the pole-pairs p , however in the single tooth wound machine it is a reciprocal function of the number of Design considerations for fractional-slot winding configurations of ... Design considerations for fractional-slot winding configurations of synchronous machines Abstract: This paper presents some design considerations for synchronous machines characterized by a fractional number of slots per pole per phase. The main advantage of this configuration is a smooth torque, which is due to the elimination of periodicity between slots and poles. A second advantage is a higher fault-tolerant capability, making the machine able to work even in faulty conditions. However ... Alternators:Short-pitch Winding : Pitch factor/chording factor ...

Armature windings of alternators are different from that of d.c machines. Basically, three phase alternators carry three sets of windings arranged in the slots in such a way that there exists a phase difference of 120° between the induced e.m.f.s in them.In a dc machine, winding is closed while in alternators winding is open i.e., two ends of each set of the winding are brought out. dc motor - why dc machines have double layer winding why dc machines have double layer winding? Double layer windings fall into two main classes depending upon the value of SSP-integral slot winding when SPP is an integer and fractional slot winding when SPP is a fractional number. To meet the requirement of symmetry among phases, the number of slots phase (S/3) must be a whole number.
