Abstract :
The superior features like rugged and simple construction and direct online starting of induction motors lead to its diversified application. However, the obligation towards reduction of the carbon emission needs highly efficient motors. Synchronous Reluctance Motors (SynRM) possesses the same merits as induction motors. Also, SynRM has an upper edge over Permanent Magnet motor technologies and switched reluctance motor technologies because of cost-effectiveness. The work described in this paper addresses new rotor design modification of the existing induction motor rotor for constant speed applications with improved efficiency. The novel design is based on the variations in barrier size and its placement. The analysis is carried out using Finite Element software. A 1/2HP induction motor as a reference motor has been utilized for the proposed conversion to direct online SynRM (DOL-SynRM). The modified motor has been investigated to determine its synchronous operation as well as its efficiency. The results demonstrated the size and location of the barrier greatly affect the performance of direct online SynRM. The analysis determined the best-fit size of the barrier to evaluating the optimum performance.
