Induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
Induction motor has a stator and a rotor
Stator has a set of coils that are supplied with AC current
This current creates a magnetic field that rotates around the stator
Rotor is made up of conductive bars and is placed inside the stator
The rotating magnetic field induces a current in the rotor bars

Servo motors
A servomotor is a rotary actuator that allows for precise control of angular position, velocity, and acceleration.
It consists of a motor, a feedback device, and a control circuit.
It is commonly used in robotics, automation, and CNC machines.
The feedback device provides information about the motor's position and speed.
The control circuit uses this information to adjust the motor's output.
Servomotors are known for their
Transformers are of two types - step-up and step-down.
Step-up transformers increase voltage and decrease current.
Step-down transformers decrease voltage and increase current.
Other types include isolation transformers, autotransformers, and instrument transformers.
Transformers can also be classified based on their core material - iron core, air core, or toroidal core.
