Example 29.13 (a). Find the load and full-load speeds for a four-pole, 220-V, and 20-kW, shunt motor having the following data : Field-current = 5 amp, armature resistance = 0.04 ohm, Flux per pole = 0.04 Wb, number of armature-conductors = 160, Two-circuit wave-connection, full load current = 95 amp, No load current =9 A. Neglect armature reaction.
