Career Episode 3 Introduction This career episode is about the project that I created as part of my final examination for my AC/DC Motors subject during my second year as an Electrical Engineering student at Mindanao University of Science and Technology. As part of my final examination, I was given a task to rewind a single-phase AC motor and present it to my instructor, Mr. Abella who is one of the head in the Electrical Technology department. Background During the duration of my AC/DC Motors subject in my second year, the fundamentals of electric motors were discussed to us such as the different parts of the DC and AC motors, their uses and their functions. Topics like why do we use electric motors and what are the appropriate motors …show more content…

After removing each part, I write and document it in a notebook so I have a guide when I assembled it again. Little parts of the motor such as screws and washers are easily lost therefore counting, documenting and placing it in a safe storage is very important. Lost parts such as screws in the casing or yoke can make the motor unstable and wobbly when it will be energized. CE 3.4 After removing the casing, the screws and the washers, I documented and wrote the present configuration of what is inside the motor such as the number of poles, the number of brushes, the configuration of the armature, rotor and the windings. The next thing that I did was to observe the windings in the armature slot. I pulled the windings going towards me so that it will protrude a little bit and so that cutting will be easy. After that, I cut the coils of the windings. These windings are magnetic wires. CE 3.5 It was taught to us during the theory discussion of the subject that there are two kinds of winding, the lap and the wave winding. After cutting the windings and observing it, I concluded that the motor’s configuration is a lap winding because the end of one winding is connected to the armature slot, the other winding’s end is also connected to it. Both windings are under the same pole. CE 3.6 There are also two types of lap winding. The simplex and the duplex. The simplex
