UNIT – VI Hysteresis Loop (AC Current) Faraday’s Law • Faraday's law of induction is a basic law of electromagnetism relating to the operating principles of transformers, inductors, electrical motors and generators. In fact, the same dc machine can be used interchangeably as a generator or as a motor. Each DC machine can act as a generator or a motor. • The end of the coils are bent and tied together to assure mechanical strength. To explain the operation of transformer and motor we need to follow the Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. A DC generator converts mechanical DC Machines - Electrical Engineering (MCQ) questions and answers Home >> Category >> Electrical Engineering (MCQ) questions and answers >> DC Machines 1) If E b is the back emf of d.c. motor and V is the terminal voltage, then the condition for maximum power is Simple Brushed DC Motor AC Induction Motor Brushless DC Motor.
