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
What are the three probable areas of trouble in a split phase motor? The bearings, windings, and the centrifugal switch.
The equivalent electrical circuit of a dc motor is shown in figure 5.2. It can be represented by a voltage source (Va) across the coil of the armature. The electrical equivalent of the armature coil can be described by an inductance (La) in series with a resistance (Ra) in series with an induced voltage (Vc) which
Brushless motors are a bit similar to normal DC motors in the way that coils and magnets are used to drive the shaft. Though the brushless motors do not have a brush on the shaft which takes care of switching the power direction in the coils, and this is why they are called brushless. Instead the brushless motors have three coils on the inner (center) of the motor, which is fixed to the mounting. On the outer side it contains a number of magnets mounted to a cylinder that is attached to the rotating shaft. So the coils are fixed which means wires can go directly to them and therefor there is no need for a brush. The reason why QuadCopters use brushless motors instead of normal DC motors is the much higher speeds and less power usage for the same speed. The brushless motors are more efficient as there is no power lost as there is in the brush-transition on the DC motors. Usually rated with a KV rating (revolutions per volt). This is not equivalent to torque, but lower KV motors are usually used for larger
Qualitative proposal paper is still continuation of previous paper in a way it will state the statement of problem, give justification with evidence on why the study of electric propulsion is relevant and worthy of doctoral-level, state the purpose statement and research question. The difference with this paper is, it will goes little bit deeper on the discussion of potential signature paper in a qualitative methodology, discussing two articles in an overview manner on the research method and design, giving specific qualitative design, sample, data collection analysis of data and trustworthy of the end result. The end of the paper, it focus on the major strength and challenges of the hypothetical study and any ethical consideration
Consider vehicles as well as hustling? Verify on your own in NN. We have one of the most useful product scientific research electric motor in the course, indicating that every little thing functions the method it does reality be informed. Recorded specifications, dyno representations, furnishing lays out and also drove race sizes will certainly aid you place your understanding to make use of.
In a normal motor set-up, there are different mechanical and electronic components, for example, the admission complex, flash attachments, Mass wind stream/Volume wind stream, and so forth. Present day motors utilize the utilization of an ECM to give the best harmony in the middle of execution and emanations. Through the OBD correspondences convention, the electronically controlled parts of the motor can be altered in the process known as 'mapping'. Changing so as to map can either be performed the product inside of the ECU (chip tuning by means of firmware adjustment), or by giving false information through module equipment (piggybacking). Mechanical segments can likewise be supplanted, for example, turbochargers or
Brushless permanent magnet DC motors are being manufactured and used increasingly in everything from home appliances to automobiles due to their inherent advantages. The merits of these motors could be enhanced further according to another design approach method which alters the typically used winding parts for low to medium power range motors. This paper deals with the high power brushless DC motor used for traction in a 48 V golf cart system.
The difficulty that my partner and I had while building the machine was putting the medium motor in a stabled way. Since our machine needed a wheel on the top and the bottom we had to use
Pictured above, is a parallel HEV system, as made obvious by the position of the electric motor and
When it comes to choosing a career path there are various questions one must consider. What do I want to do for the rest of my life? How much money will I make? What population will I work with? What kind of skills will I need? For me, I knew very early on that I wanted a career that focused on helping people. This budding interest to help others, coupled with the suicide of a close childhood friend is what lead me to pursue a career in social work. After starting the BSW program here at Wayne State University, I knew that I had made the right career choice. However, I soon learned that if I wanted to be the best social worker that I could be, I would have to further my education and obtain my master’s degree.

I would also like to acknowledge and appreciate the role of mechanical workshop staff and instructor Mr Jason Knapp for permitting me to work on the machines for my reports and also for some helpful tips.
I have successfully completely my Bachelor’s degree in Accounting and have over five years of work experience. There are several notable achievements in my professional career. I have always left a positive mark on my employers and looked for ways to make a difference in every position. For instance, I once took an initiative to update the organization’s processes for creating internal reports. I built custom queries in Oracle to address various vendor inquiries and aging report to view the outstanding balances. This effort had an immediate impact on several departments, which drastically saved time and increased productivity.
Stator winding is cooled by Flow path I . This flow path passes through the stator bars via insulated barbefor this it passes through the water manifold on the exciter end of the generator which is connected to thestatus bars by a separate hose.Cooling water flows through hollow strands inside the bars. At the turbine end, the water return to the primary water tank which comes from another water manifold which in turn comes from the similar hoses.Minimum temperature rise is obtained for both the bars and the coolers because the water folw is single pass through the stator. Movements are relatively minimised which are caused due to the different thermal expansions between the bottom and the top bars.
The second part consists of the gearhead, power generator, and flywheel. These components are use to convert the motion into useful energy.
