Drive performance evaluation of linear switched reluctance motor using a current source inverter

This paper presents drive performance evaluations of a linear switched reluctance motor (LSRM) driven by a current source inverter (CSI). First, we describe a new drive circuit with CSI for the LSRM drive. For deliberations of drive performance evaluations, a simulation model is built by a circuit simulator. The drive performances of the LSRM with the proposed drive circuit are compared with a traditional voltage source inverter. As a result, it is confirmed that a deterioration of thrust with increase in velocity and an efficiency characteristics are improved by using the proposed drive circuit.
