This handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments is increasing.

Previously this type of motor operated at fixed speed, but recently it has been integrated more and more in processes at variable speed. For this reason it seemed useful, or necessary, to write a handbook on the various aspects of the motor itself, its control and finishing with the diagnosis aspect.

An asynchronous motor is used in industry nowadays where variation speed and reliability are required. For sensitive systems, we must decisively know the state of the process and inform the operator of the appearance of any anomaly and its severity.
