Abstract:

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 conformity of the design parameter’s stage in this study, the calculated values of the magnetic field and cogging force characteristics are compared with that of their desired values. Also, the proposed configuration is compared to a 6-4 and 3-phase conventional LSRM with similar number of stator teethes, number of phases, and constraints in volume. From the numerical analysis of a proposed novel configuration, it has been observed that this machine produces higher force per unit volume and almost similar cogging force when compared to a conventional LSRM with identical number of stator teethes, number of phases, and constraints in volume. The obtained primary electric and magnetic characteristics for the proposed configuration are verified with the help of 2-D FE computations.
