I applied via Instahyre and was interviewed before May 2023. There were 2 interview rounds.

Round 1 - HR 

(3 Questions)

  • Q1. Family background
  • Q2. Tell me about yourself
  • Q3. What's your salary expectation
Round 2 - Technical 

(5 Questions)

  • Q1. What is speed difference between stator's rotating magnetic field and rotor's rmf?
  • Ans. 

    The speed difference between stator's rotating magnetic field and rotor's rmf is called slip.

    • The slip is necessary for inducing current in the rotor and producing torque.

    • The slip is typically around 1-3% in most induction motors.

    • Higher slip values can indicate issues with the motor such as overload or mechanical problems.

  • Answered by AI
  • Q2. What is induction motor
  • Ans. 

    An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.

    • Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.

    • They do not require brushes to transfer power to the rotor, making them more reliable and maintenance-free compared to brushed DC motors.

    • The speed of an induction motor is determined by the frequen...

  • Q3. What is synchronisation
  • Ans. 

    Synchronisation is the process of coordinating multiple systems or devices to work together in harmony.

    • Synchronisation ensures that different components or processes are aligned in time.

    • It is commonly used in electrical systems to ensure that multiple generators are running in phase with each other.

    • In data communication, synchronisation is important for ensuring that data is transmitted and received at the correct timi...

  • Q4. What is the speed of a rotor with respect to the stator magnetic field in an induction motor?
  • Ans. 

    The speed of a rotor with respect to the stator magnetic field in an induction motor is known as slip speed.

    • The slip speed is the difference between the synchronous speed of the rotating magnetic field in the stator and the actual speed of the rotor.

    • It is necessary for the rotor to operate at a speed slightly slower than the synchronous speed in order to induce current and generate torque.

    • The slip speed allows the roto...

  • Answered by AI
  • Q5. What is slip? Per unit slip?
  • Ans. 

    Slip is the difference between synchronous speed and actual rotor speed in an induction motor. Per unit slip is the slip expressed as a fraction of synchronous speed.

    • Slip is the difference between synchronous speed (speed of the rotating magnetic field) and the actual rotor speed in an induction motor.

    • Per unit slip is the slip expressed as a fraction of synchronous speed, typically denoted as a percentage.

    • For example, ...
