This learning track covers a comprehensive understanding of electrical machines, with a primary focus on transformers and Direct Current (DC) machines. It starts with the basics of transformers and magnetic circuits, moving on to the mechanics of transformers, their efficiency, regulation, and equivalent circuits. The track further delves into the types, functions, and mathematical expressions related to transformers. It also provides a detailed understanding of three-phase transformers, their construction, connections, and applications. The track then shifts its focus to DC machines, explaining their operations, characteristics, and the principles of armature winding. It also covers the effects of armature reaction, the role of compensating winding, and the distribution of armature current along the air gap of the machine. The track concludes with a comprehensive understanding of DC motors, their operations, control mechanisms, and braking. It also covers the functioning, characteristics, speed control, operation of universal motors, and testing methods of DC series motors.
