چکیده
his paper investigates the influence of the rotor structure, more specifically, the influence of the open angle between the two magnet’s segments of each V-shape pole on the general characteristics of the machine keeping always the same magnets volume. In fact the investigation is done by using a free Finite Elements Methods (FEM) program coupled with another optimization program. This obtained methodology is used to analyze a wide range of first and second order phenomena like the average and oscillation of torque, cogging torque, torque-speed characteristics.

متن کاملTorque Ripple Reduction in Switched Reluctance Motors by Rotor Poles Shape and Excitation Pulse Width Modification
In this paper, at first, a 24/16 three-phase switched reluctance motor is designed, then the rotor poles shape tips corrected for reduction ripple of single-phase torque waveform. By doing this, the single-phase torque waveform has a flat surface and consequently, the single-phase torque ripple is reduced. Also, due to the commutation between the machine phases, the torque drops during this tim...
متن کاملStudy on Application of Two Different Magnetic Materials in Rotor of Cylindrical Synchronous Generator to Produce Reluctance Torque
Synchronous generators are of two type’s salient pole type and round rotor type. The load angle curve of a cylindrical rotor synchronous machine comprises a single sine term only while in salient pole synchronous generators, power-angle characteristic has two terms. The first term is the fundamental component due to field excitation (the same as the cylindrical rotor) and the second term ...
متن کاملElectromagnetic field analysis of novel low cogging force, linear switched reluctance motor, based on 2-D finite element method
This paper deals with electromagnetic design and 2-D (two-dimensional) magnetic field analysis of novel low force ripple linear switched reluctance (LSR) motor. The configuration that has been presented here has a higher number of rotor poles than stator poles, and the purpose of this configuration is to improve the force ripple, which is the weak point of LSRMs. In order to illustrate the ...
متن کاملA Markovian Approach Applied to Reliability Modeling of Bidirectional DC-DC Converters Used in PHEVs and Smart Grids
In this paper, a stochastic approach is proposed for reliability assessment of bidirectional DC-DC converters, including the fault-tolerant ones. This type of converters can be used in a smart DC grid, feeding DC loads such as home appliances and plug-in hybrid electric vehicles (PHEVs). The reliability of bidirectional DC-DC converters is of such an importance, due to the key role of the expec...
