The field form of a three phase, 50 Hz, 10 pole star connectedalternater has a spatial flux density distribution given byexpression B = sinθ +0.3 sinθ +0.2 sin5θ +0.1sin7θ Tesla . The machine has 180 slotes and has a twolayer winding with 3-turn coil. Each coil spans 15 slotes, the coilbeing connected to 600 groups.The armature diameter is125 c.m. and core length 45 c.m.. Determine (a) the expression forthe instantaneous emf per conductor (b) the expression for theinstantaneous emf per coil (c) the r.m.s. phase and line voltages.
