Analysis of Linear Switched Reluctance Motor having gashed pole

19 Jun 2014-pp 1-3
Abstract: In this paper, the results of a finite element analysis are carried out on new stator geometry of a four phase Linear Switched Reluctance Motor (LSRM). In the new geometry, stator pole faces are gashed. LSRM performance for variable load conditions is discussed. The two dimensional (2-D) finite element analysis (FEA) results, have demonstrated validity of the proposed new design.

Abstract: Optimal precalculation of the position-phase current projile for current feeding a 4-phase, 4 kW switched reluctance motor, results in a single input, linear. decoupled output torque controller, which provides low torque ripple. A bicubic spline interpolation was used to model the non-linear experimental data. The algorithm is bused 011 minimizing both the average and peak current hence improves the dynamic performance of the novel six switch, current fed, igbt 4 kW, 40 kHz inverter. Test results by instuntaneous speed measurement over the speed runge 100-300 rpm, ruted torque, open-loop optimizing technique are presented,

Abstract: High starting force with reduced volume and mass are the primary importance in most of the linear transportation applications. This paper presents a novel tilted Linear Switched Reluctance Motor (LSRM) with reduced mass, volume, force ripple and improved force profile. Three Dimensional (3-D) finite element analyses are carried out on the proposed design to estimate the performance the motor. A thorough comparison has been made between the basic and the proposed structures. Experimental results reveal that, the proposed design is well suited for high starting force applications.

Abstract: Higher torque ripple is one of the few drawbacks of switched reluctance motor (SRM) drives which otherwise possess excellent characteristics for applications in many commercial drives. This paper begins with an extensive review of torque ripple reduction methods that appear in the literature and then presents a new strategy of PWM current control for smooth operation of the drive. This method includes a current control strategy during commutation when torque ripple minimization is of utmost importance.

Abstract: The converter topology with a minimum number of power devices and control implementations to facilitate the pulsation-free force control of the linear switched reluctance machines are investigated for the first time in this paper. The minimization of the devices offers cost reduction, compact packaging, and enhanced overall reliability. With that in view, a topology with 3N/sub sc/+3 devices is chosen where N/sub sc/ is the number of sectors in the linear machine. The propulsion force with conventional control of single-phase excitation has high-commutation torque pulsation and it is overcome with a multiphase excitation strategy, proposed in this paper. Further, the proposed control strategy reduces the normal force pulsation. A systematic step-by-step design procedure of the switching strategy for the converter known as unipolar switching strategy, proportional plus integral current controller, and gating control strategy of a long linear switched reluctance machine is presented. Experimental correlation of the proposed converter arrangement and control strategy is presented with a 4.8 m-long linear switched reluctance machine in achieving the stated objectives.
