Critical wavelength concept is proposed in the paper in order to describe the different behaviors of eddy currents and different harmonic losses in solid poles or non-insulated laminated poles of electrical machines. The concept is developed from an eddy current model which is commonly used for the calculation of slotting effects in solid rotors. Two synchronous machines are used for illustrating...
It is significant to understand the effect of slot skew on the performances of electrical machines, e.g. quality of voltage wave and fluctuation of electromagnetic torque. Since finite element simulations can make the analysis processes very time consuming and complicated, An analytical method for calculating the airgap inductances of windings in electrical machines with skewed rotor or stator slot...
