Force Ripple

This paper presents the realization and design of a linear switched reluctance motor (LSRM) with a new stator structure. One of the setbacks in the LSRM family is the presence of high force ripple leads to vibration and acoustic noise. The proposed structure provides a smooth force profile with reduced force ripple. Finite element analysis (FEA) is used to predict the force and other relevant parameters.A frequency spectrum analysis of the force profile using the fast Fourier transform (FFT) is presented.The FEA and experimental results of this paper prove that LSRMs are one of the strong candidates for linear propulsion drives.

Transportation Applications

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.
