Abstract

A theoritical analysis of linear synchronous motor LSM fed by a current source inverter is presented. The analysis is carried out at the two ends of speed range using entirely two different models. The low speed model assumes a perfect rectangular current waveform which is established in the armature windings. So, the thrust is calculated from the product of specific electric loading and specific magnetic loading. The high speed model assumes that the commutating capacitors are permanently connected in parallel with the LSM and the resulting parallel commutation is fed by a quasi-square current waveform. The equivalent circuit which des-cribes the LSM during commutation is presented and the output power is calculated.
