The induction motor is a most important drive in the production area. These motors are used in various industrial applications. They can be protected from the different mechanical and electrical faults using different protection systems. The protection is very important to detect abnormal motor running conditions such as over current, over voltage, overload, over temperature, and unbalance conditions. In the classical protection systems, the time delay is adjusted constantly without considering the fault level. This paper presents protection system for induction motor based on Sugeno Inference. The time delay is computed by this intelligent protection for different faults. The obtained results are interesting and show the interest of the proposed intelligent protection.

W artykule zaprezentowano system zabezpieczeń silnika indukcyjnego bazujący na Sugeno Inference. Określano opóźnienie czasowe dla różnych rodzajów błędów. W stosunku do istniejących systemów proponowany system umożliwia bardziej precyzyjne określenie błędów.

The contribution deals with the use of fuzzy regulators, which are used for modelling and identification of insulating materials for electrical rotary machines. For this purpose, we have used the fuzzy controller with the Sugeno fuzzy inference engine. The objective of this contribution is to outline the problems of adjusting the Sugeno fuzzy controller and determining what of the parameters have dominant influence on the time curve of the identification process of insulating material. By using the term "identification process", we understand the determination of the insulating material parameters on the basis of which it is possible to predict the lifetime of the insulating material.
