Variety of Characteristic Magnetic Material on Permanent Magnet Synchronous Generator (PMSG)

Abstract

Wind energy conversion system, one of the main components is a Permanent Magnet Synchronous Generator (PMSG). During the past two decades, many types of permanent magnet generators for wind power applications have been the research topic. This study focuses primarily on designing a PMSG to create, simulate, and analyze an internal permanent magnet topology with twelve slots and eight poles. The simulation was carried out at a rotational speed of 1000 revolutions per minute, using several types of permanent magnet materials: Ceramic 11, SmCo 26/26, and NdFeB 48/11. The result of the analysis shows that permanent magnets applied in the design of a generator impact its output power and efficiency. At 15 ohm and 60 ohm loads, SmCo 26/26 and NdFeB 48/11 are the only ones that fulfill the specified requirements in this investigation. The permanent magnet type with the most optimal characteristics is Neodymium Iron Boron 48/11 because it has a high flux density, thus causing the electrical energy generated to be greater than other types of permanent magnets. The 48/11 NdFeB permanent magnet generates the most output power, which is 2110.86 watts when loaded with 15 ohm. The best efficiency of 89.38 percent for the PMSG twelve-slot eight-pole configuration occurs when the load is 15 ohm using the 48/11 NdFeB permanent magnet.
