The no-load and shunt field current of a 300 V, four-pole, wave-connected DC shunt motor are 10 A and 3 A, respectively. Its full-load current and armature resistance are 80 A and 0.2 Ω, respectively. At no-load, the flux per pole is 0.05 Wb. The motor has 800 conductors and the contact drop per brush is 1 V. The field flux is reduced by 2 percent due to armature reaction. Analyse this motor in the following ways: 4.5.2 Determine the no-load speed.
