    Comparison of a flux barrier and a salient pole synchronous reluctance machine for high rotational speeds in electric traction applications

    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

    On fuzzification mechanisms for unary quantification

    We address a salient issue arising in Gloeckner's two-step methodology for modeling vague quantifiers: the design of quantifier fuzzification mechanisms (QFMs). These are mechanisms to turn formal models of vague quantifiers operating only on crisp arguments (semi-fuzzy quantifiers) into vague quantifiers accepting vague arguments as well (fully-fuzzy quantifiers). We critically examine desiderata formulated by Gloeckner for QFMs and also point out that previous approaches to quantifier fuzzification largely ignored the question whether the resulting quantifiers can be expressed in suitable extensions of t-norm based fuzzy logics, in particular in Lukasiewicz logic. We also introduce a new family of QFMs, and assess how it fares with respect to the mentioned desiderata. We exclusively focus on unary quantifiers, in order to circumvent interference with vagueness related problems arising for all truth functional accounts of quantifiers that refer to more than one argument formula
