In this paper rotor topologies of synchronous reluctance machines are compared with regard to electrical traction applications. Electrical machines for electric vehicles are usually operated in a wide speed range including flux weakening. In contrast to permanent magnet synchronous machines and induction machines synchronous reluctance machines have advantages of a very simple and cost effective rotor design, which makes this machine type very interesting for this application. For synchronous reluctance machines different rotor topologies as salient poles or flux barrier designs are known and both are investigated in this work regarding high speed operation in flux weakening range. Because of the mechanical strength limitation of flux barrier machines a salient pole machine is proposed, although design steps to accomplish the same machine harmonics characteristic of the salient pole type have to be implemented. Finally, both machines provide sufficient operation in the whole speed range. However, the machines show slightly different behavior and require different manufacturing technologies for the stator winding and the rotor.
