Document Summary

Sectioiv: one hand-written non-photocopied formula sheet is allowed in this exam, you must show the steps of your calculations. No marks will be given to correct final answers if the steps are incorrect: no questions to be asked during the exam. In the magnetic structure of figure 1. the winding has 160 turns. All dimensions are in mm. and 1/i = 800000 h/rn. Figure 2, is propelled by a separately excited l)c motor hich is coupled with the vehicle"s wheel by a 10:1 gearbox. = 0. 1 fl and the ilux constant of k = 0. 4 nm/a, and is energized by a variable power supply. The radius of the vehicle wheels is r = 0. 5 m. (a) calculate the armature terminal voltage if the vehicle travels at a speed of v. Q3: a fan motor for an automobile cooling system is of the permanent-magnet type.
