In addition to these, armature winding of alternator can also integral slot winding and fractional slot winding. Single Phase Armature Winding. Single phase armature winding can be either concentrated or distributed type.. Concentrated Armature Winding. The concentrated winding is employed where the number of slots on the armature is equal to the number of poles in the machine. Articles - Pro Slot Ltd. In slot car motors the rotor (armature) is very small. Not only in length, but most critically in diameter. Its this small diameter and light rotating weight that makes it difficult to balance this tiny piece--if its size were not enough, slot car motors usually operate at very high RPM. electrical machine design - Kings College of Engineering Stator slots 48, conductors per slot 30, rotor slots 53, one bar per rotor slot, length of each bar 12 cm, area of bar 0.6220cm2, mean diameter of end rings 18cm, area of ring 1.5cm 2. Full pitch winding with phase spread for stator. Specific resistance is 0.021 Ω/m length per mm area. 21. i. What is the relationship between armature turns and ... The armature turns will decide the amount of magnetic flux that can be produced while the conductor size will determine how many will fit in the armature slots…Both will determine the amount of magnetic lines of force and the strength of the magnetic flux that will be developed…
