The study proposed a design of magnetization yoke of ferrite spoke-type permanent magnet synchronous motor. A high magnetic field intensity(H) is required for the magnetization of permanent magnet, meaning that the analysis of nonlinear finite elements methods is needed considering saturation of core. The permanent magnet is placed deeply to the shaft especially in spoke-type motor. The high H, however,...
This paper presents optimal magnet shape of the spoke type interior permanent-magnet synchronous motor for using the ferrite magnet. Normally an electric motor used the ferrite magnet has lower output power and efficiency than an electric machine using the rare-earth magnet. Nevertheless, because the price of a ferrite magnet is chipper than a rare-earth magnet, the motor design using a ferrite magnet...
