Questiona A4 Pole, lap wound DC shunt motor has a 220 V supply. The armature has 1000 conductors and resistance of Os. If the useful flux per pole is 20 mWh. When Mechanical load is applied it takes 20 A current (Neglect the field Current). Calculate the (a) Total current (b) Induced Voltage (which opposes the supply voltage) (c) Speed of the DC motor (d) Torque Developed (c) At the time of starting of DC shunt motor induced voltage Value 151 Page - 6 - of 9 Questiona A4 Pole, lap wound DC shunt motor has a 220 V supply.
