This paper proposed a simple strategy for parameters identification of switched reluctance motor (SRM) direct instantaneous torque control. without rotor locking includes measuring and calculating steps. In the step, flux linkage curves with current at three critical positions are obtained. At intermediate position, curve is measured under chopper control (CCC). aligned unaligned when winding given voltage pulse. whole flux-linkage characteristics position can be calculated based on curves....
Purpose This paper aims to clarify the relationship between stator tooth shape and DC voltage fluctuation of a double salient hybrid excitation generator (DSHEG). It analyzes asymmetrical characteristics magnetic circuit inductance each phase. The study reduce by using optimization scheme, which helps reducing difference. Design/methodology/approach opted for method combined with theoretical analysis, simulation experimental verification. scheme is given based on analysis Taguchi method. A...
This paper proposed an optimum design of 4/3 SRM (switched reluctance motor) for fuel pump in HEV. The structure and principle is briefly introduced the equivalent magnetic circuit analyzed. To acquire larger torque production lower ripple, rotor geometry controlling parameters are optimized. Furthermore, stator improved considering both radial force vibration model. frequency low harmonic order proved much than resonance so will be reduced.
This paper proposes a new optimum design method of switched reluctance motors (SRM) based on direct instantaneous torque control (DITC) algorithm. The total copper losses minimization the motor has been investigated through adjusting stator pole arc and rotor in order to improve efficiency motor. Meanwhile, ripple can be limited within range because use DITC method. optimal is processed combining FET MATLAB simulation. simulation comparisons are also presented 12/8 validate proposed scheme.
In this paper, a description and operating principles of novel hybrid excited synchronous generator are presented for EVs. The excitation source is produced by two permanent magnets different sizes field windings. latter can regulate the magnetic density air gap then adjust output DC voltage current. advantage to match engine power with battery charging characteristics. addition, several factors discussed achieve an optimum extended range mileage.
