   Engineer Design of Levitation Electromagnet
By Patoèka M., Huták P., Feiler Z. [View]
[Download]

Abstract: The paper deals with the engineer design of the levitation magnet for transport systems or magnetic bearings. The optimal solution for the minimum whole volume of iron and copper is showed. The optimisation has been based on the idea, that all the linear dimensions of the magnet are expressed as multiples of the longitude module. It allows comparing the technical utility features of the different dimension magnets with different modules. This problem is solved as a part of the project CEZ J22/98:26 22 000 10

   Model Development and Design of a Wheel-Motor Drive System
By Godoy Simoes M., Vieira P.Jr. [View]

Abstract: An interactive methodology where a prototype is followed by refinements of the model requirements and a design that cycles back into the development of the final model is called protocycling. A protocycle methodology can be used in the design of novel electrical machines for evaluation of suitability and optimization issues: volume, torque/current ratio, bus voltage, losses and transient response. Drive systems and control strategies have been advancing promises and improvements in electric machine performance for EVs applications. Therefore, optimization of efficiency, weight, volume and wider range control are possible with good modeling for analysis and development. The present paper shows how a five phases direct-drive high torque wheel-motors machine was modeled by the interaction of the construction and electromechanical issues in order to achieve a dynamic model, useful for control strategy implementation. The dynamic model was implemented with Simulink/MATLAB and then used to design the control strategy and validate a DSP based torque loop control.

   Theory and Application of Oscillating Electrical Motors
By Kudarauskas S. [View]
[Download]

Abstract: The article analyses classification of electrical machines by the temporal and spatial properties of mechanical movement. It is purposive to group the machines by movement temporal properties thus marking out an independent group of oscillating machines. The article demonstrates operation principles, design diversity and practical utilisation of these machines. There are presented principles of theoretical analysis of main regime (i.e. steady oscillations). The appendix presents rationale of analogy between electrical circuit and magnetic circuit from energy standpoint.
