This paper presents results of magnetic characteristic ana lysis of a magnetic flux concentration type surface magnet motor. Firstly influence of number of the rotor poles on the to rque characteristics was examined for fixed stator construc tion and then some constructions of the permanent magnet array were tested to reduce the cogging torque. Their magnetic flux distributions and torque characteristics were calculated by using the finite element method. Permanent magnets with strong magnetism are widely used in daily life. Especially, role of the permanent magnet material used in the motors is very important for our social life, because we can reduce input energy and improve efficiency by using the perma nent magnets. The magnetic energy of the permanent magnets is directly converted into the rotational force, without supplying current to generate the magnetic field of the field system such as the three-phase s ynchronous motors. Miniaturization of the motors utilizing the permanent magnets has being done with progress of the performance of the permanent magnet materials. Recently, technology to generate a strong magnetic filed ove r 4T in a local region by combining the NdFeB permanent magnets has been developed. As a result, it came to be able to obtain larger magnetic energy than that of the magnet pole's surface due to the resid ual magnetization. There is a possibility of a further characteristic improvement of the permanent magnet motors by using the powerful energy produced by combining the NdFeB permanent magnets. However, the applications of strong magnetic field to the permanent magnet motors are limited and a new appl ied technology has not progressed yet. In order to develop a small size and high power motor, higher magnetic flux density in the air gap needs to increase torque and power under a constant revolution speed. Concentration type permanent magnet arrangement is one of the effective solutions to generate high magnetic flux density as mentioned in the above. We have developed a new surface permanent magnet synchronous motor by using the concentrated permanent magnet arrangements. The same magnetic poles of the assembling permanent magnets on the rotor surface are faced to each other to generate larger magnetic flux density in the air gap. We call this the concentrated surface permanent magnet synchronous motor (CSPMSM). In this paper, the torque characteristics depending on magnet arrangements are numerically examined by using the finite element method (FEM).
