Here, I have not defined any wire cross-section, so I am assuming the resistance is calculated by considering the fill factor as 100% of the area defined as the coil. Am I correct here? If this is the case, then the resistance is not correct. As in actual practice the fill factor is not 100%. How can I correctly calculate the resistance without modelling the coil? The excitation is the current excitation here.<\/span><\/li>\n<li class=\"MsoListParagraph\" style=\"margin-left: 0cm\"><span lang=\"EN-GB\">When the motor is excited with current, the induced voltage for the winding is the sum of back-emf + the resistance drop.
