Measuring, Registering and Recording the vectors' characteristics of Induction Machines

Evolution of power semiconductor devices and power static frequency converters is a key factor in development of advanced applications. Availability of energy sources derived adjustable frequency AC motor allowed to reach a new horizon in research studies and technical applications, completely untapped today.However, the advantages inherent in the operation of adjusting the frequency cannot be fully exploited without adopting a proper control strategy, which is essential in characterizing the parameters and the overall performance of a command system. Control techniques are to ensure a fair and effective command of the operation. During normal operation, the nominal engine and inverter must be secured and the engine order should be placed in area of maximum torque. In case of overloads or faults of another nature, redesigning of installation parts is preferable in order to adopt advanced operating strategies and to determine the parameters.
