Analiza silnika synchronicznego o rozruchu bezpośrednim i magnesach w wirniku rozłożonych w kształcie litery U

In the paper transients under starting process and steady states of line start permanent magnet synchronous motor have been analyzed. Computer simulations have been performed using field circuit model of the LSPMSM elaborated in the Maxwell environment. The structure of the rotor with permanent magnets arranged in "U" shape per pole has been used. It was assumed that the stator is made on the basis of mass-produced 3-phase, 4-pole, 3 kW squirrel-cage induction motor. The influence of supply voltage and coils turn number of the stator phase winding on the starting and functional parameters in steady state of the motor have been investigated. Selected results and conclusions have been presented.
