The presented study examines the effect of voltage subharmonics, which relates to components of the frequency less than the fundamental voltage harmonic, and the currents and vibration of the line start permanent magnet synchronous motor. The obtained experimental results corresponded to a production motor with a rated power of 3 kW and a rated speed of 1500 rpm. The main purpose of our study was to highlight that the subharmonic value had a non-linear effect on the vibration level of the considered motor. It was found that for subharmonic values up to approx. 0.5% of the vibration level could be considered acceptable for long-term operation, whereas vibration caused by voltage subharmonics of values greater than approx. 0.8% might promote machine damage.

A line start permanent magnet synchronous motor (LSPMSM) supplied with distorted voltage is analysed. The study is based on the field–circuit model. The algorithm for solving the equations of the model is discussed. In the analysis of the selected states of the motor the non–linearity of the magnetic circuit and skewed slots of the rotor are taken into consideration. In order to verify the developed algorithm and software, among others the startup process of the motor has been examined. The electromagnetic torque and phase currents are calculated. The results of computations have been compared to the results obtained using the commercial FEM package Comsol Multiphisics. Selected results of simulation tests are shown.

Artykuł prezentuje analizę możliwości zastosowania silnika synchronicznego wzbudzanego magnesami trwałymi o rozruchu bezpośrednim typu LSPMSM (Line-Start Permanent Magnet Synchronous Motor) do napędu przenośnika taśmowego. W artykule przedstawione są wyniki symulacji komputerowej rozruchu i pracy napędu przenośnika z napędem oryginalnym oraz z zaproponowanym modelem matematycznym silnika LSPMSM. W programie symulacyjnym został zamodelowany cały układ napędowy, składający się z silnika napędowego oraz obciążenia. Symulowany był rozruch i praca przenośnika dla różnych prędkości transportowych ustalanych przełożeniem przekładni. W artykule przedstawione zostały wyniki symulacji rozruchu i pracy przenośnika dla wybranej prędkości transportowej, natomiast w podsumowaniu została przedstawiona analiza porównawcza parametrów elektrycznych i mechanicznych nowego napędu w stosunku do napędu oryginalnego dla 3 prędkości transportowych i 2 napięć zasilających.

In the paper the transients under starting process and the steady states of squirrel-cage motor (IM) and line start permanent magnet synchronous motor (LSPMSM) have been compared. The original stator of 3 kW induction motor type Sg 100L-4B, was used in both structures. In order to determine opportunities to increase energy parameters of LSPMSM the heating curves of both motors were compared. In LSPMSM the rotor with aluminum and copper cage was used. The basic operating parameters of the two structures which are characterized by identical stators were tested. Particular attention has been given to the transient under starting process. Efficiency, power factor and current in the stator windings obtained during measurements for both structures have been presented. The paper focuses on achieving a much higher output power for LSPMSM than an induction motor of the same size. The selected results of experimental tests were shown.
