A 10-hp, 230-V, 500-r/min shunt motor, having a full-load armature current of 37 A, is started with a four-point starter. The resistance of the armature circuit, including the interpole winding, is 0.39 , and the resistances of the steps in the starting resistor are 1.56, 0.78, and 0.39 ,in the order in which they are successively cut out. When the armature current has dropped to its rated value, the starting box is switched to the next point, thus eliminating a step at a time in the starting resistance. Neglecting field-current changes, armature reaction, and armature inductance, find the initial and final values of the armature current and speed corresponding to each step.
