Outer rotor permanent magnet machines have been applied to low-speed and high-torque applications for their high moment of inertia and torque density. The 12-slot/10-pole outer rotor fractional slot permanent magnet machine model is established by the finite element analysis (FEA) in this paper, and the no-load back EMF, air-gap flux density and flux distribution of the machine are preliminarily simulated and verified. The stator tooth width of outer rotor permanent magnet machine is analyzed, and five different schemes of stator tooth width are designed. It is proved that the torque density can be effectively improved by using reasonable armature tooth width and auxiliary tooth width by FEA. At last, the reason of improving the output torque is explained by the analysis of the magnetic density and the winding coefficient of the armature tooth.
