Switched reluctance machines (SRMs) are potential candidates for use in the propulsion systems of electric vehicles. However, they suffer from low power density and high torque ripple. In this paper, a segmented rotor double-sided axial flux SRM (DSAFSRM) is chosen detailed analysis. A hybrid design algorithm proposed to take effects iron non-linearity into account. The procedure benefits simpl...

Switched reluctance motors (SRM) becomes increasingly popular due to its simple structure and dependability. It seems have a two-pole configuration. A stator had also centralized coils along each pole, whereas rotor has an iron core only. As result, the switched motor is anticipated be low cost, incredibly robust variable-speed machine. Because only made up of laminated coils, performance heavi...

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...

Outer-rotor switched reluctance machines (SRMs) have drawn much attention as promising candidates for in-wheel direct-drive motors of future electric vehicles. This article presents a systematic performance comparison three outer-rotor SRM topologies traction applications in terms the specific torque, electromagnetic efficiency, torque ripple, radial force, and mechanical aspects. A generalized...

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...

This paper investigates the effect of rotor flux screens (conducting screens) on performance switched reluctance motors with a higher number poles than stator poles. A high decreases torque ripple, which is desirable for electric vehicle applications. The conducting fill interpolar gaps forming cylindrical hence alleviating windage losses, especially effective at speeds. screen thickness and ma...

This paper describes a speed sensorless vector control method of the torque for cost-effective parallel-connected dual induction motor fed by a single inverter. A natural observer with load torque adaptation is employed to estimate the speeds of the same rating induction motors connected in parallel and fed by a single inverter. The speed difference between the two induction motors for unbalanc...

The advancement on Wireless Sensor Networks for vibration monitoring presents important possibilities for helicopter rotor health and usage monitoring. While main rotor blades account for the main source of lift for helicopters, rotor induced vibration establishes an important source for understanding the rotor performance and blade condition. A discussion on the dual character of blades as rot...

Nowadays the use of the Switched Reluctance Motors (SRMs) has been considerably increased in various home and industrial applications. Despite of many advantages of this type of motors, such as simple structure, low cost, and high reliability, the main disadvantage of them is the generation of high torque pulsation. This paper presents a novel method to optimize a typical SRM such that the torq...
