Abstract：This paper deals with a new method called equivalent open slot method for calculating the Carter Factor of closed slot submersible motors. Two analytical methods including conventional method and improved method were introduced to calculate the Carter Factor and the results are compared with the finite element method to find a proper analytical method for open slot machine. Then we first proposed that the closed slots can be replaced by open slots because the flux density in the slot bridge is highly saturated. Permeability ratio method and geometric method are introduced to calculate the Carter Factor by considering the fringing effect and the magnetic saturation of the slot bridge. Models with different closed slot types are constructed and finite element computations in turn validated the equivalent open slot method including permeability method and geometric method.
