Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Power flow in the Induction motor is as shown below.
Rotor input or air gap power,
Rotor copper losses,
Mechanical power developed or shaft power output is
Now mechanical power developed (Po) in terms of the air gap (Pag) will be (1-s) Pag
∴ Po = (1 - s) Pag
Where, s = slip
Additional Information
The relation between the rotor air gap power, rotor copper losses, and gross mechanical power output is,
