Coreless Permanent Magnet machines are increasingly used in many industrial applications, such as automotive and aerospace applications, wind turbines, medical equipment, robotics, servo drives, etc. In coreless PMDC machines, the rotor has a coreless winding structure and due to the absence of iron core, the permanent magnet plays significant role in these machines. Also, the shaft’s material can change the flux distribution and is another effective parameter on machine performances. Thus in this paper, a typical coreless PMDC brushed machine is simulated and the effects of magnetization direction and the amount of the residual flux density of permanent magnet, and also the influence of ferromagnetic and non-ferromagnetic material of the shaft on machine performances, are studied and analyzed through 3D finite element analysis. The results show that using of ferromagnetic shaft with diametrical magnetized PM can improves the machine performances in motor mode.
