Squirrel-Cage Torque

01/10/2011 9:53 AM

When operated at rated voltage and frequency, a three-phase squirrel-cage induction motor(of the design classification known as a high-slip motor) delivers full load at a slip of 8.7 percent and develops a maximum torque of 230percent of full load at a slip of 55 percent. Neglect core and rotational losses and assume that the rotor resistance and inductance remain constant, independent of slip. Determine the torque at starting, with rated voltage and frequency, in per unit based upon its full-load value.

I did my own homework to get to where I am, I suggest you do the same, assuming you are pursuing an Engineering degree.

If you are pursuing a degree in Management, I perceive you are well on you way to learning how to get other smarter people to do your work for you. Congratulations!

Roll up! Roll up! Nice cheap calulator batteries for the lazy student! Just fell off the back of a Space Shuttle! Just send cash! <Splutter, wheeze, sneeze, dribble>
