Electrical Engineer fresher Interview Questions and Answers

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

• This current creates a magnetic field in the rotor that interac...read more

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 high accuracy and repeatability.

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.
