I am given the rated values of a squirrel cage induction motor:
A 300hp, 2300V, 3‐phase, 60Hz squirrel‐cage induction motor turns at a full‐load speed of 590r/min. What is the approximate value of the rotor I2R losses?
However, the synchronous speed is not given, nor are the amount of poles in the motor. How would one solve this problem without knowing these values?
