A two-dimensional (2D) analytical method is presented for predicting the armature-reaction field in the slotted opening airgap/magnet region of a permanent magnet (PM) disc-type generator. The current in the slot is equivalent to the uniform distributed current sheet along an arc of the slot opening. The effects of stator slot openings are being accounted for by the introduction of a 2D relative permeance function which is calculated directly from the nonlinear equation described by conformal transformation. A more refined permeance distribution can then be obtained subsequently.
