Method for determining the heating up of an electrical rotating machine

摘要

The method involves measuring a first overheating value of a moto-ventilated electric rotating machine while a rotor is immobilized with respect to a stator. A second overheating value of the machine is measured while the rotor rotates at reduced rotation speed without load. A third overheating value of the machine is measured while the rotor rotates at nominal rotation speed without load. Overheating of the machine against nominal functioning conditions is calculated by adding a difference between the first and second overheating values with the third overheating value. An independent claim is also included for an installation for determining overheating due to totality of thermal losses of a moto-ventilated electric rotating machine against nominal functioning conditions.
