Electromechanical Systems Quiz

What does the armature do in an electromechanical system?

• Generates a magnetic field

• Stores electrical energy for later use

• Converts electromagnetic energy into mechanical movement

• Converts mechanical energy into electrical energy

What is the role of the bearings in the system?

• To ensure smooth rotation by reducing friction

• To transfer energy to mechanical components

• To reverse the direction of the current

• To generate electrical current

What do the brushes maintain contact with?

• The armature

• The field windings

• The drive shaft

• The commutator

What is the function of the commutator?

• To support the drive shaft

• To reduce friction

• To reverse the direction of the current

• To produce a magnetic field

What does the drive shaft do?

• Produces a magnetic field

• Generates electrical energy
