Abstract

Power consumption of refrigerator is the top three among the various household appliances. This is because of the lack performance and efficiency of the conventional refrigerator compressor system. This paper describes about the design of linear permanent magnet motor for reciprocating air-vapor compressor application. There are various types of linear motor technologies and topologies for air-vapor compressor that have been discussed, such as, linear induction machine, linear synchronous machine, linear DC machine, and linear permanent magnet machine. The significant designs criteria considered are based on their force capability, higher efficiency, simplicity and cost-effectiveness. Among the linear motor technologies reviewed, a linear permanent magnet machine is the most preferable technologies for the reciprocating air-vapor compressor application due to the high thrust capability and efficiency. There are three categories of the linear permanent magnet, which are, moving-coil, moving-iron, and moving-magnet. This paper is mainly focused on the moving-magnet topologies which considered a tubular permanent magnet, a slotted and a slotless stator, and also a different type of magnet configuration for the reciprocating air-vapor compressor application. The linear permanent magnet topologies have been studied and analyzed in order to obtain the best three designs for the reciprocating air-vapor compressor application. ANSYS software, ANSOFT Maxwell, is used to draw and analyze the proposed designs to get the results of air-gap flux distribution, air-gap flux density and the respective graph. The result for the three designs will be compared discussed in order to choose one best design for air-vapor compressor application. In conclusion, the best design obtained can be apply for air-vapor compressor to increase efficiency, performance and reduce the energy consumption as well.
