Expert Solution

Step 1

“Since you have posted a question with multiple sub-parts, we will solve the first three sub-
parts for you. To get the remaining sub-part solved please repost the complete question and
mention the sub-parts to be solved.”

Given information:

A shunt motor is lap-wound with 83 slots and 6 turns per phase.

The supply voltage across which motor is connected is $V_{t} = 230$ Volts.

The speed of the motor is $N = 1000$ rpm.

Total armature resistance is $R_{a} = 0.15 Ω$ .

Armature current is $I_{a} = 60$ A.

Since brush voltage drop is not given so we can ignore it.

We need to determine CEMF, conductor loss and mechanical power of the motor in KW and HP.
