Zagadnienia doboru przemienników częstotliwości do zasilania silników reluktancyjnych o rozruchu asynchronicznym

The paper presents test results concerning the influence of the kind of frequency converter used on static and dynamic parameters of a drive with reluctance motor at asynchronous startup. Vector- and scalar controlled converters most widely applied in the industry underwent tests. It was found that there exists the dependence between the kind of converter employed and the parameters of the drive with this type of reluctance motor. The frequency of input voltage modulation also influences the dynamic parameters. Basing on the study carried out, it was demonstrated that SVL vector controlled converters should be mainly used for the powering of such kind of motors. Vector controlled frequency converters of higher quality may introduce engine trouble, as far as the work of drives with such motors is concerned.
