1. A 200 V shunt motor has armature and shunt field resistances of 0.15 Q and 1250, respectively. When running light, it takes 6 A and runs at 1200 rpm. A series winding of 0.05 is added to make it long shunt commutatively compounded. This winding increases the flux per pole by 25% when the motor is taking its full load current of 100 A. Neglecting armature reaction, solve for the operating speed as a compound motor.

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.
Question
Please Answer Question number 1.
Transcribed Image Text:1. A 200 V shunt motor has armature and shunt field resistances of 0.15 Q and 1250, respectively.
When running light, it takes 6 A and runs at 1200 rpm. A series winding of 0.05 is added to
make it long shunt commutatively compounded. This winding increases the flux per pole by 25%
when the motor is taking its full load current of 100 A. Neglecting armature reaction, solve for
the operating speed as a compound motor.
2. A four-pole machine generates 250 V when operated at 1500 rpm. If the flux per pole is
1.85x10 Maxwells, the number of armature slots is 45, and the armature winding have four
parallel paths. Calculate the number of conductors for each slot.
3. A series motor takes 285 amperes and develops 153 Ib-ft torque when operating at 1200 rpm.
Calculate the torque for a speed of 1700 rpm under the condition the current drops to 210
amperes and the flux is decreased by 18%.
