The working of a DC motor is well explained in this video with the help of animation. Construction details of DC Motor, Shunt & Series motor, concept of back EMF are also explained in this video.
Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment, such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical systems of automobiles and aircraft. Electronics engineers, on the other hand, design and develop electronic equipment, including broadcast and communications systems, such as portable music players and Global Positioning System (GPS) devices. Many also work in areas closely related to computer hardware development.
The field of electric power engineering deals with the generation, transmission, and distribution of electricity.These include transformers, electric generators, electric motors, high voltage engineering, and power electronics. Electrical engineers maintain an electrical network called the power grid, that connects a variety of generators using high-voltage transmission lines. Control engineering applications range from flight systems of commercial airplanes to industrial automation. Where there is regular feedback, control theory can be used to determine how the system responds.
Electrical engineers must have a bachelor's degree in a related discipline. Employers value internships or participation in cooperative engineering programs. Courses include digital systems design, differential equations, and electrical circuit theory. Programs in electrical engineering may be accredited by ABET. At some universities, students can enroll in a 5-year program that leads to both a bachelor's degree and a master's degree concurrently.
A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one's career. Licensed engineers are called professional engineers (PE). A professional engineer can oversee the work of other engineers, sign off on projects, and provide services directly to the public.
Certification programs enable electrical engineers to learn new skills and demonstrate their expertise to potential employers. To earn certifications, candidates often complete training programs followed by a written or oral exam.
The EIT certification is an important entry-level certification for engineers in a wide variety of fields. It's often the first step in earning a Professional Engineer (PE) certification. The National Council of Examiners for Engineering and Surveying administers EIT testing in all states during four periods each year. After passing the EIT exam, the candidate's state engineering board issues them the certification, which allows them to work as an entry-level engineer in their area.
The initial Fundamentals of Engineering (FE) exam can be taken after earning a bachelor's degree. Engineers who pass this exam commonly are called engineers in training (EIT) or engineer interns (EI). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering exam. Each state issues its own licenses, although states recognize licensure from other states. Electrical and electronic engineers may advance to supervisory positions in which they lead a team of engineers and technicians.
Artificial Intelligence and Machine Learning - research covers a wide range of topics of this fast-evolving field, advancing how machines learn, predict, and control, while also making them secure, robust and trustworthy.

As a technology it plays a key role in virtually every aspect of modern life including for example entertainment, communications, travel, health, defense and finance.
Systems Theory, Control, and Autonomy - Theoretical research includes quantification of fundamental capabilities and limitations of feedback systems, inference and control over networks, and development of practical methods and algorithms for decision making under uncertainty. From distributed systems and databases to wireless, the research conducted by the systems and networking group aims to improve the performance, robustness, and ease of management of networks and computing systems.
Ask yourself if you can see yourself being a engineer, working with technical concepts and complex equipment, which can be challenging. While engineering classes and internships will prepare you well, certain innate qualities that you bring to bear will help you succeed.
Axial flux motors are considered the ultimate future of electric vehicles and of electric aviation because they have a high torque-to-weight ratio, ideal for aircraft. The first-ever electrical generator, developed by Michael Faraday, was an axial flux type. You can see the axis of rotation is parallel to flux lines.
Every AC machine uses a rotating magnetic field (RMF), an invention that kicked off the industrial revolution.
This hundred-year-old motor—invented by the great scientist Nikola Tesla—is the most common motor type. In fact, about 50 percent of global electric power consumption is due to induction motors.
Alternators are also referred as synchronous generators. Construction details of the generator, functions of slip rings, armature coils, Automatic Voltage regulator (AVR) and pole core are explained.
Overall employment of electrical and electronics engineers is projected to grow 7 percent over the coming decade. The rapid pace of technological innovation will likely drive demand for electrical and electronics engineers in research and development, an area in which engineers will deploy solar arrays, semiconductors, and fiber optics.
The need to upgrade the nation's power grids will also create demand for electrical engineering services. Electronics engineers who work for the federal government research and evaluate electronic devices used in aviation, transportation, and manufacturing. They may work on federal electronic devices and systems, including satellites, flight systems, radar and sonar systems, and communications systems.
