Bharat Forge Interview Questions and Answers

3ph induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• Three-phase AC power is supplied to the stator winding, creating a rotating magnetic field.

• This rotating magnetic field induces a current in the rotor, which in turn creates its own magnetic field.

• The interaction between the stator and rotor magnetic fields causes the rotor to rotate, converting e

1 HP is equal to 746 watts.

• HP stands for horsepower, a unit of power used in the automotive and manufacturing industries.

• Watt is the SI unit of power.

• The conversion factor between HP and watt is 746.

AC drive is used for controlling the speed of AC motors, while DC drive is used for controlling the speed of DC motors.

• AC drive is based on the principle of changing the frequency of the input voltage to control the speed of the motor.

• DC drive is based on the principle of changing the voltage applied to the motor to control its speed.

• AC drives are commonly used in industries for applications like pumps, fans, and conve...read more

A scale is a device used to measure weight or mass, while an encoder is a device used to convert motion or position into digital signals.

• A scale is commonly used in households to measure the weight of objects or people.

• An encoder is often used in robotics or automation systems to determine the position or speed of a motor.

• Scales can be analog or digital, with digital scales providing more accurate measurements.

• Encoders...read more

Quality Assurance focuses on preventing defects while Quality Control focuses on identifying and correcting defects.

• Quality Assurance is a proactive process that involves planning, designing, and implementing processes to prevent defects from occurring.

• Quality Control is a reactive process that involves identifying defects and taking corrective action to eliminate them.

• Quality Assurance is focused on the entire process...read more
