Comparative study of integrated radial-axial flux rotor motor using ferrite magnet

We have previously proposed an integrated radial-axial flux rotor permanent magnet synchronous motor for EV traction motor, and confirmed that the motor had almost the same performance as an IPMSM, which uses sintered NdFeB magnet, based on a computer simulation. Our next target is general industrial-use motors, whose design policy is different from EV traction motors with a requisite forced cooling system. This paper describes a comparative study based on computer simulation using FEA and the experimental results in a compared motor, which is the comparison between our IRAF-PMSM and an IPMSM for general industrial-use.
