| Abstract [eng] |
Permanent magnet synchronous motors (PMSM) utilization rate is increasing in industry today. Due to this fact high efficiency ratio of PMSM reaches IE5 premium class efficiency. Therefore, the efficiency coefficient of PMSM variates from 92% to 97% that is why this type of motor is replacing traditional asynchronous motor by falling into efficiency classes of IE1, IE2, IE3 and IE4, ranging from 75% to 92% in industry. Thus, the object of the research is method for efficiency determination of permanent magnet synchronous motor application in order to identify and verify the variating parameters. In this article innovative and safe method of PMSM testing is presented through the research when nominal parameters of the motor are unknown. Also, the comparison of PMSM oscillograms with different types of load types and phase shift oscillograms, generated by using operation amplifier, are analyzed in the research which is scrutinized in the article. During the designing process PMSM is projected for IE5 premium efficiency class. But after the production PMSM sometimes does not match the nameplate parameters which are declared by the factory. As a result, during the testing procedures PMSM nameplate parameters did not match the projected parameters. Facing the problem of projected and tested efficiency mismatch, the PMSM highest efficiency determination experiments were performed in laboratory in order to prove the highest efficiency of PMSM. The outcome data showed different PMSM input parameters. Furthermore, the experimental results of PMSM testing were confirmed with electrical machines theory and simulation results were performed with electrical circuits. |
