Abstract

In this paper, new stator pole tip geometry has been investigated. The new stator pole tip and conventional stator pole tip SRM are analyzed using Finite Element Analysis (FEA). It is observed that a small change in stator pole tip geometry results in a significant change in the characteristics of motor. The new stator pole tip results in more flux linkages and hence more saturation of motor at same current. The new pole tip is further analyzed by constructing 5 designs of the SRM with different pole tip parameters and doing a single phase and two-phase FEA analysis. It is observed that with certain pole tip parameters, the single phase torque has a smooth profile. Using the FEA data, torque profile for two phase operation of motor, is generated for the above 5 designs. Minimum torque ripple obtained for all the designs are compared. It is observed that by choosing the stator pole tip parameter properly, the torque ripple can be optimized for a particular motor operation.
