Analiza charakterystyk trakcyjnych silnika liniowego synchronicznego współpracującego z przemiennikiem częstotliwości

The paper concerns of the analysis of traction characteristics of the linear synchronous motor (LSM) fed from frequency inverter. The conducted examinations served for the quality assessment of the new type of drive. During attempts and tests of LSM drive was being encumbered with different types of burdens. Received courses were of help for analysis of the drive in terms of his accuracy and the precision. Analysis consisted on comparing with oneself individual stages of the move, for the maximum and minimum load. For every type of the burden a relative error corresponding to the entire sequence of the move was appointed. The conducted examinations confirmed the superiority of the drive, and agreeable parameters with declared by the producer. With evidence of it there is a relative error get in the process of calculations, for the maximum load of the motor, of which the value is on the level 1.5 %.
