Question
Download Solution PDFIn an induction motor, the relationship between gross mechanical power developed and rotor input is _______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGross mechanical power developed = (1 - S) × Rotor input
Concept:
Power flow in the Induction motor is as shown below.
The relation between the rotor air gap power, rotor copper losses and gross mechanical power output is,
\(\Rightarrow {{P}_{in}}:{{P}_{cu}}:{{P}_{g}}=\frac{1}{s}:1:\left( \frac{1-s}{s} \right)=1:s:\left( 1-s \right)\)
where
s is the slip
Pin is power developed in the motor
pg is the air gap power of the motor
