  1. Useful Approximations for Normal Running and Overload Conditions of Squirrel-Cage Motors • “Normal” running conditions • No load to 15% overload • Rated voltage • Rated frequency • For these conditions, slip is usually <0.03 • Make some simple approximations

  2. for very low values of slip

  3. Rotor Current, Rotor Torque are both directly proportional to the slip

  4. Rotor Current and Developed Torque as functions of slip The motor is loaded from it’s running no-load condition Notice slip = 0 is here --->
