This paper presents an optimum design process and operational analysis of a permanent magnet-assisted synchronous reluctance motor (PMASynRM) as a low-cost and highly efficient consumed magnet material machine. The motor's topology is based on inserting partial permanent magnetic materials into flux barriers of an original synchronous reluctance motor (SynRM) that implicitly increase the difference between the machine's inductances, thereby increasing output torque. The procedure of rotor design as the main contribution of this paper is carefully illustrated. The rectangular shape of the flux barriers was found to achieve cost reduction and improve productivity. The impact of the permanent magnet added to the rectangular flux barriers and how it decreases the q-axis flux are described. For analytical studies, the optimum structure of a sample machine for high-power application is designed through the 2D finite element method in a Maxwell environment. For the sample machine, it is shown that the optimum number of flux barriers, optimum insulation ratio, and optimum width of permanent magnets in order to maintain the rating level of output and minimize the ripple are 4, 0.375, and 30 mm, respectively. In addition to demonstrating the operation of the motor with and without permanent magnet material, the performance of the hybrid motor is evaluated with two different permanent magnet materials, ferrite and NdFeB. Simulation results show that despite a negligible rise of ripple torque, the PMASynRM is able to achieve a higher output torque than the original SynRM with a low amount of permanent magnet material.
After the arrival of new technologies to communities, the way of using these technologies in organizations had been encountered with several developments. An organization's authorities necessarily need to understand that today accountability and acceptance responsibility in organizational serving criteria has been reached into the field of information technology. Dependency of organizations and employees and referrers, as well as organizational processes and procedures on information technology tool has doubled the necessity to take seriously the issue called information technology universality in server organizations. Therefore, information technology universality is an organizational advantage. Organizations need to be managed effectively in information technology universality for serving in order to succeed. The purpose of this article is to provide appropriate and desirable strategies for serving by spreading the use of information technology. The effective factors on spreading the use of information technology for serving have been firstly identified in this article. Then, the current and desirable status of organization in terms of the use of information technology has been investigated. In continue the appropriate strategies have been provided to apply information technology for serving in this institution while identifying critical factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
