This paper presented a novel analytical method for calculating magnetic field in the slotted air gap of spoke-type permanent-magnet machines using conformal mapping. Firstly, flux density without slots and complex relative air-gap permeance of slotted air gap are derived from conformal transformation separately. Secondly, they are combined in order to obtain normalized flux density taking account into the slots effect. The finite element (FE) results confirmed the validity of the analytical method for predicting magnetic field and back electromotive force (BEMF) in the slotted air gap of spoke-type permanent-magnet machines. In comparison with FE result, the analytical solution yields higher peak value of cogging torque.

Abstract EVANOHM alloy S offers optimum stability and flexibility with regard to both size and required temperature coefficient of resistance. Its extremely low electromotive force vs copper together with its high electrical resistivity are highly desirable properties in a precision resistance wire. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as joining. Filing Code: Ni-373.
