Amer Group Interview Questions and Answers

Armature working principle is the basic principle of operation of an electric motor, where a current-carrying conductor experiences a force in a magnetic field.

• Armature is a rotating part of an electric motor or generator.

• When current flows through the armature winding, it creates a magnetic field.

• The interaction between the magnetic field and the current in the armature produces a torque, causing the armature to rotat...read more

I use tools like 5 Whys, Fishbone Diagram, and Pareto Analysis to find the root cause of a problem.

• Utilize the 5 Whys technique to ask 'why' multiple times to get to the root cause of the problem.

• Create a Fishbone Diagram (Ishikawa diagram) to visually map out potential causes of the problem.

• Conduct a Pareto Analysis to identify the most significant factors contributing to the problem.

• Use tools like Scatter Diagrams, C...read more

The critical process in windings is the winding insulation process.

• Proper insulation of windings is crucial to prevent short circuits and ensure the longevity of the equipment.

• Insulation materials such as varnish, epoxy, or insulation tapes are used to coat the windings.

• The insulation process must be done carefully to avoid any gaps or voids that could lead to electrical failures.

• Testing the insulation resistance is im...read more
