THERMAL STATE MODIFICATION
If a CMR induction motor is fully loaded it is equivalent to a temperature of 100%, as far as the thermal replica is
concerned. The motor protection relay is normally set to trip when the temperature reaches 100%. However, a
stator temperature of 100% does not necessarily correspond to a rotor temperature of 100%, the rotor
