Abstract

Electrification in railway industry offers better performing trains with reduced pollution and maximised capacity. SynREL is gaining more interest as a candidate for traction application in place of IM due to its simple and robust structure. Consequently, induction machine (IM) and synchronous reluctance machine (SynREL) are designed and compared for same electrical (1.5 kV and 170 A), thermal and mechanical specification in this paper. IM is found to have a higher torque capability than SynREL for the same torque speed characteristics. Around 67% of the torque at both rated and maximum speed of operation is achieved by SynREL in relation to the specification. The absence of rotor cage improves the efficiency and reduces the weight of SynREL However, SynREL is found to suffer from poor power factor.
