Comparative Performance Analysis of Surface Mounted Permanent Magnet Synchronous Generators

Öz

One of the generator types used in producing electrical energy is permanent magnet synchronous generator (PMSG). In this study, a surface located permanent magnet synchronous machine with a 1.5 kW inner rotor was used as a reference generator. The finite element analysis of this generator was conducted via Maxwell Rmxprt software. As a result, phase current and voltages waveforms were measured at a rated load. The characteristics of the PMSG under loaded and unloaded working conditions were examined through the measurements on the experimental setup designed in Electrical Machines Laboratory at the Faculty of Engineering of Manisa Celal Bayar University. The values obtained from the open-circuit tests were compared with the simulation and manufacturer's catalog data. This paper also contrasted line voltages measured and simulated at 450 rpm as rated speed.
