The work provides a theoretical and experimental study on the iron loss of an energy efficient synchronous reluctance motor without starting winding powered by a frequency converter. The concepts of basic and additional load losses in the magnetic system of this motor are introduced. Based on the results of the theoretical study, a no-load test procedure was proposed for the motor under consideration,...
This paper describes some aspects of the mathematical modeling and the experimental study of the magnet-free synchronous reluctance motor (SynRM) of IE5 efficiency class (rated power is 750 W, rated speed is 3000 rpm, rated efficiency is 89.5%). The proposed mathematical model allows minimizing the number of the boundary problems which is to be solved and allows calculating power, losses, torque waveform...
The article is devoted to the comparative research of performances of controlled drives with a synchronous reluctance motor (SynRM) and with an induction motor (IM) in a pump application. In this study the performances of the motors are represented as iso efficiency maps. The issues include the calculation of the payback time of commuting of the IM drive to the SynRM drive. It is shown that the application...
This paper presents the results of the development and pilot study of the highly efficient synchronous reluctance motor. The results include a detailed comparative analysis of the performance values of various modes of the developed synchronous reluctance motor and the series induction motor of the same power made in the same housing. These motors heating and other parameters have been compared. The...
