The project leader is the co-organizer and the vice-chair of the international scientific committee of the biennale Symposium on Applied Electromagnetics (SAEM) (http://www.users.pjwstk.edu.pl/~ptze/SAEM08/Welcome.html). The symposium is devoted to exchanging ideas, presenting achievements of established and also junior researchers, in topics related to applied electromagnetics. The members of the project team have presented 6 papers, mainly related to design, modelling and analysis of electric devices and drives, which is directly connected to topics of the applied research project.
B.01 Organiser of a scientific meeting
COBISS.SI-ID: 12600342The scientific committee of the IEEE CEFC 2008, which is one of two most important events from the field of electromagnetic field computation in 2008, has awarded the best poster paper award (see Appendix 2) to members of the project team. As presented in the awarded paper, the authors and members of the project team have shown how it is possible to join theoretical and practical knowledge from the field of design, control and modelling of electric machines, optimization methods and experimental methods in order to solve complex problems in a relatively simple way.
E.02 International awards
COBISS.SI-ID: 12540694This work evaluates the braking performance of line-start interior permanent magnet synchronous machines (LSIPMSMs), which may be employed for shortening of stopping-times in large-inertia drives, braking energy recuperation and in passive brake systems with explicit dynamics. The comparative analysis is based on measurement data of voltage, current, output power and rotor speed in dependence of the braking torque produced by the two tested LSIPMSMs, one with a symmetrical three-phase and one with a symmetrical two-phase stator winding.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 13808406The work presents the correlation between the usage of different stator and rotor slot number combinations, magnetic flux density distributions, no-load iron losses and rated load winding over-temperatures for a specific induction motor (IM). The motor’s magnetic field was analyzed by traces of the magnetic flux density vector, obtained by FEM. Post-processing of FE output data was used for posterior iron loss calculation of the motor iron loss at no-load. Presented is a comparison of calculated and measured iron loss values for a four pole IM with 5 different slot number combinations.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 12351766This work presents an experimental method appropriate for determining magnetically nonlinear characteristics of hybrid electric machines such as the line-start interior permanent magnet synchronous motor. It has been shown that the currents induced in the machine damping windings or squirrel cage disturb the flux linkage characteristic determined by formerly known methods and therefore, only the final points of each hysteresis loop, where the currents induced in the damping windings already died-out, can be used as correct points of machine’s magnetically nonlinear iron core characteristic.
