FAQs on Working of Induction motor Video Lecture - Electrical Machines - Electrical Engineering (EE)

1. What is an induction motor?
Ans. An induction motor is a type of AC electric motor where power is supplied to the rotor by electromagnetic induction, rather than a direct connection. It is one of the most commonly used types of motors in various industrial applications.
2. How does an induction motor work?
Ans. Induction motors work on the principle of electromagnetic induction, where a rotating magnetic field is created in the stator, which induces a current in the rotor causing it to rotate. This rotation is what drives the mechanical load connected to the motor.
3. What are the main components of an induction motor?
Ans. The main components of an induction motor include the stator (stationary part), rotor (rotating part), and the housing that encloses the motor. The stator is typically made of laminated steel with windings to create the magnetic field, while the rotor can be squirrel cage or wound type.
4. What are the advantages of using an induction motor?
Ans. Some advantages of using an induction motor include simple design, low maintenance requirements, high efficiency, and the ability to operate in harsh environments. They are also cost-effective and reliable for a wide range of applications.
5. How can the speed of an induction motor be controlled?
Ans. The speed of an induction motor can be controlled using methods such as changing the frequency of the power supply, adjusting the number of poles in the motor, or using variable frequency drives (VFDs). These methods allow for precise control of the motor speed to suit different applications.
