Abstract :
Expanding Part I of our contribution, this paper deals with the analytical calculation of the tangential forces in brushless dc machines, where we extend previously developed methods using conformal mapping and the Maxwell stress theory to enable a greater applicability of such methods. While Part I focuses on the explanation of the methodology itself, aiming to convey the overall picture and not to obscure the message with lengthy developments of formulae, this present Part II provides the detailed developments of the different expressions that are important for those to carry out further research in this area.
