Induction motor is also known as
Rotating Transformer
Singly excited motor
Asynchronous motor
All of these
All of these
The correct answer is D (All of these) because an induction motor is commonly referred to as a rotating transformer due to the transformation of electrical energy into mechanical energy. Additionally, it is classified as a singly excited motor and operates asynchronously, which emphasizes its characteristics.

Induction motors operate on the principle of electromagnetic induction where an alternating current (AC) in the stator winding creates a rotating magnetic field that induces a current in the rotor. This induced current interacts with the magnetic field, producing torque and causing the rotor to turn.
An induction motor operates on the principle of electromagnetic induction.
It is commonly called a rotating transformer due to its nature of energy transformation.
Robust construction and low maintenance requirements.
High efficiency and reliability in various applications.
Variable speed operation can be challenging without additional control systems.
Low starting torque compared to some other types of motors.
Used in industrial drives and machinery.
Widely utilized in HVAC systems, pumps, and fans.
Induction motors are designed for efficiency and are less expensive than synchronous motors.
Option B is incorrect as itтАЩs rather a specific categorization that does not encompass the broader functionality of induction motors.
D is correct тАФ An induction motor is often referred to as a rotating transformer and functions asynchronously, making all provided options valid.
Understand the differences between various motor types, especially their operational principles, to answer related questions effectively.
