| dc.description.abstract | Electric motors are the workhorse of the modern industries and consume about 70 % of the industrial electrical demand. Constructing motors with better efficiency can result in a reduction in energy consumption and cost savings to the consumer. The solution of increasing a motor’s efficiency is to use permanent magnets motors which eliminate the excitation losses experienced by induction machines, thereby increasing the motor’s efficiency. The past 25 years have been a significant period with advances in the development of line start permanent magnet motors. Over this period, these motors have expanded their presence in the industrial and domestic marketplace. LSPMSMs can offer higher efficiency than standard induction motors used in the industry. Due to nonlinear characteristics of magnetic materials, finite element method is considered to be a better approach for design and analysis of line start permanent magnet motors. In order to find the optimized structure, different rotor structures of line start permanent magnet motors are comparatively studied in terms of dynamics and steady state performance. The placement and volume of magnet plays a critical role in motor performance. Three types of rotors with different layers of permanent magnets are proposed and analyzed using finite element method. The performances of three motors are compared to get the best configuration of line start permanent magnet motor. | en_US |
