Sažetak
In recent years, problems of increasing energy efficiency and stability in the work of electromotor drives, gets more and more on current events. Reducing costs of production in many industries necessarily modernizing our technological processes, the introduction of modern electronic devices with raising the level of automation and modern methods of management and protection. By improvement of production motors technology, motor efficiency has been increased per volume unit significantly, which means that less volume per motor power decreases the thermal time constant, therefore the warming-up is faster under abnormal conditions. Advanced HV cage induction motors are constructed for high powers, dimensioned for the precisely defined load, also with very low permissible overload. There are many different factors which have their own influence on induction motor operating, and any deviation of some of those factors could cause the motor damage. This paper will discuss the issues of failures on high-voltage cage induction motors rotor, the causes of failures and their detection.
