What are the advantages and disadvantages of short-pitched …
WebA full-pitch winding will have coils whose average span corresponds to a number of slots equal to the pole-pitch or 360°/p whereas a short-pitch winding will span fewer slots. The … WebView Answer. 3. In the equation for RMS value of the generated EMF in a full pitched coil of an AC machine, E = E max /√2 = √2πf r NΦ, f r depends on ____________. a) rotating speed of the armature coil. b) rotating speed of the flux density wave. c) relative velocity between the flux density wave and armature coil. WebThe ratio of the voltage induced in a short-pitch winding to the voltage induced by a full-pitch winding. ... Distributed winding has the advantage of reducing harmonics in the generated emf and improving the sine waveform. It improves cooling and reduces armature reaction. Because the coil is distributed across the slots, ... c視聴率
