Determine the resistance steps in the starting rheostat for 1000-hp, 720 rpm 575 volts shunt motor, Full-load efficiency 93.4 per cent and brush drop is constant 2.5 volts. The inrush current is to be limited to 150 per cent of rated current, Armature resistance is 0.009 ohm and shunt-field resistance is 93 ohms, At what steady speed will the motor operate at each resistance step? Make a table of the resistance steps, the resistance cut out per step, the counter emf and the steady speed on each step. Hint: Since the field winding is connected to the line voltage the flux is constant therefore the speed varies directly with the counter emf.
