In this paper, a novel 42 slot, 20 pole ironless winding for use in an axial-flux machine is presented. The proposed design improves the utilization of the available air gap area and is based on the implementation of the winding as a printed circuit board (PCB). Besides, it is compared with a conventional 21 slot, 20 pole ironless axial-flux winding regarding the criteria: torque generation and induced...
This paper deals with the analytical calculation of torque in PM machines with surface mounted magnets. The calculation is based on the cross-correlation of stator and rotor flux density. As a consequence of the Parseval's theorem, the magnetic cross-energy, given by a space-dependent function, is equal to the sum of the components of the spectral energy density in the frequency domain. By using the...
In the following paper, an analytical approach for the calculation of the the induced emf in windings of electrical machines is provided. This method uses the complex Fourier series that describe the stator winding function and the magnetic flux density distribution in the air gap that is caused by the rotor permanent magnets. By using a special case of the Parseval's theorem, the induced emf can...
