Abstract
This paper proposed a calculation method of the torque and power density especially for the fractional-slot concentrated winding machines. The torque coefficient and the inductance coefficient to transform from m-slot/n-pole machine to 3-phase/2-pole machine are used. Some machines were designed and these torque densities and power densities are compared. Experimental results showed the effectiveness of the proposed calculation method and have good accordance with both calculation results and FEA results.
