While electrical machine designers typically go to great lengths choose the optimal number of stator slots based on electromagnetic performance, often thermal aspects this selection are overlooked. This article investigates multi-domain impacts related slot selection, combining both and aspects. Taking an existing 42-kW 4-pole, 12-slot with Halbach-array surface-PM rotor, used within a more-ele...

This paper describes a unified approach to modeling and simulation of hydraulic systems using bond graphs. Unlike the others, the causalities are not applied in bond graph settings. This leads that mathematical model is generated in the form of differential algebraic equation (DAEs) and solved as such by suitable solver. Bond graph model of simple hydraulic system has developed using program Bo...

We present an efficient algorithm for solving the one-dimensional cable equation in the Laplace (frequency) domain for an arbitrary linear membrane. This method, a reformulation and extension of the geometrical calculus developed by Butz and Cowan (1974), solves for the transfer impedance between any two points in a branched cable structure of arbitrary geometry (but without loops) by the repet...
