The feasibility study of the application of a synchronous reluctance motor in a pump drive

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 of SynRM in a pump drive is able to assist to significant improving of efficiency of pump installation.
