Description
Summary:Measurement and determination of parameters of single-phase induction machines is quite a difficult task in comparison with symmetrical three-phase induction machines. This paper describes three different methods for parameter determination of single-phase machines. Conventional (classical) method, usually used for three-phase machines, is complemented by Suhr's and two-phase method. Furthermore, measured parameters are supported and confirmed by means of finite element method and calculations based on electrical machine design. The gained parameters are used in simulation model of single-phase machine in steady-state conditions in stable region and subsequently compared with measurement on a small real motor. Simulation results show a good agreement with behavior of a real machine. Finally, an easy method for the replacement of two-phase supply is described.
