Q5- Adjust a fire angle for a three-phase full-wave semi-controlled converter to feed the separately exciter DC motor to get a load torque can be reached to 750 rpm. When the supply voltage of converter is 150 volts per-phase and the absorbed current through the armature 40A with resistance 0.2 a and a constant back emf 0.4v/rpm. Then find the maximum speed for motor assume the previous parameters values are a constant.
