Radioengineering - September 2012, Volume 21, Number 3 Without dependence on predefined common control channel (CCC), Dcscap relies on the distributed message passing among CRs through their available channels, making the algorithm applicable for large scale networks. untitled Depending on the OZD ProfiAt least one bus subscriber must be switched on and Technical University OF Liberec - Faculty OF Mechanical… The computation is based on 3-D micro-mechanical model of the composite material and on the FEM analysis. The model takes into account the effects of the complex geometry of reinforcement and of different mechanical properties of each …
Investigation on Slot/Pole Number Combinations for PMSM
IMPACT OF VARIOUS SLOT-POLE COMBINATIONS ON AN IN-WHEEL ... Impact of slot-pole number variation on current density When the simulation results are assessed (Table 2), 24 slot/20 pole configuration stands higher than all other conductive current density and efficiency values. 2.2. Simulation Study for Various Slot/Pole Combinations As a result of various slot/pole combinations, the IMPACT OF VARIOUS SLOT-POLE COMBINATIONS ON AN IN-WHEEL ... In the light of these parameters, the slot/pole combinations of 24/18, 24/20, 36/24 and 36/30 which are suitable for in-wheel BLDC motor structure are investigated by means of FEA study. FEA is rather useful particularly for divergent slot/pole combinations [3, 15-17]. jimhendershot.com Skewing of the rotor poles and stator slots can also be investigated. Such modeling methods save considerable cost and time with the added benefit of revealing some very useful and not so obvious slot/pole combinations. V STATOR SLOTS/WINDINGS It is surprising that certain rotor pole, slot/winding and phase relationships seem to be quite popular.
