Discover the intricacies of electrical machine design and performance parameters, including the role of Carter Coefficients in determining air gap lengths. Abstract—The air-gap flux density in a single side slotted unsaturated machine is computed via two dimensions finite element method (2D-FEM) and via some analytical approximations. For this purpose, different approaches were used to solve the air gap field diagram using finite element method and the magnetic field distribution uniformity was evaluated by Carter's factor … In the coming lectures we will utilize this effective length of air gap equation to find the magnetic fields at the air gap and MMF's with respect to the air gap. Five formulations for calculating Carter's factor were compared, highlighting significant differences in results. The proposed methodology addresses complex air-gap geometries, enhancing … As it turns out, the effects of slots can be readily incorporated into the analysis by replacing the air gap g with a modifi ed air gap g . In particular, for the case of the stator slots, the modifi ed air … Carter coefficient is a ratio of the fundamental airgap flux density calculated for double slotted and smooth air gap. There are 25 stacks of 30 mm long, with 10 mm cooling ducts (24 ducts). Airgap is 3 mm. ### Calculate the effective core length if the rotor surface is smooth. The magnetic flux density distribution in the air-gap of single sided slotted electric machines is analyzed in the paper and the Carter's factor is computed. The finite element method (FEM) … · Slots, Reluctance, Permeance, Slot opening, Airgap length, Carter coefficient...more
