DR-10: Design of magnetization yoke to Reduce the number of Double spoke type pmsm magnetization using i-core

This paper conducted a study on the reduction of the number of split Magnetization and the prevention of irreversible demagnetization using the I-Core of a double spoke type motor. Recently, as interest in spoke-type motors using ferrite permanent magnets has increased, the need for research on magnetization and irreversible demagnetization in double spoke-type rotor shapes has emerged. However, in the existing spoke-type rotor shape, the magnet was deeply embedded in the rotor, making it difficult to magnetization. As it is important to use permanent magnets excluding rare earths in the future, the use of spoke-type motors becomes important, and design to consider magnetization and prevent irreversible demagnetization accordingly is important. Therefore, this paper proposed a magnetization yoke shape design in consideration of magnetization and irreversible demagnetization on using I-Core of Double Spoke type PMSM to solve this problem.
