The saving energy with train operation is more important than before from the view points of the global environment. However the energy saving design on the traction equipments sometimes has a trade off relation against the down sized and lighter weight traction equipments. In this paper, an optimizing method of the generic algorithm is applied to the numerical simulation to calculate the consuming...
The paper presents a complete mathematical analysis of a sinusoidal BLDC motor commutation. The motor is supplied from a DC source via a 6-leg inverter using the 120degON operation. The commutation period of 60 electrical degrees is divided into two sub-periods, for which the corresponding differential equations are solved using the initial and final conditions. The obtained model is simple to apply;...
Compared with their three-phase counterparts, multiphase machines with phase number n ges 5 have many advantages like lower torque pulsation, higher power density, better fault tolerance, etc. Due to these advantages and the increasing demands on high performance and high power adjustable speed drives, the research on multiphase drives has experienced a significant growth since the end of last century...
