Abstract
The 3D magnetic field in the region with ventilation duct of electrical machine has been analyzed. The method of reduced scalar magnetic potential in connection with the FE method has been used to solve the problem. On the basis of field distribution, the slot leakage permeance has been calculated. The problem has also been solved analytically. It has been assumed that the radial component of magnetic field density in ventilation ducts is equal to zero. The comparison of results leads to the conclusion that, in practice, the analytical calculations are satisfactory accurate.
