i) The field of separately excited DC Motor is excited by a separate single phase voltage source of 240V-RMS at 60HZ and single phase full wave uncontrolled rectifier, whereas the armature is connected to a single phase voltage source of 230V-RMS at 50HZ through a single phase full wave controlled rectifier. Name plate details of the motor shows Ra = 0.14 Q, Rf = 3502, Motor constant K = 1.35 %3D VIA-rad/sec. The motor is taking a rated armature current of 8A, and the Motor takes a 6% of the full load current under no load. Calculate the following. а. What happens to the speed of the Motor if the armature converter is fired at lower firing angles? b. Torque produced by the motor under 0.75 % of the full load. с. Calculate the speed of the Drive system, when the armature converter is fired with a firing angle of 130°. d. Calculate the firing angle of the armature converter to run the motor at 1460 RPM, under at its 60% of full load.

Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
