Download Solution PDFThe correct answer is option 4.
Function of the Armature Core in Magnetic Circuits
Magnetic Path Completion:
- The armature core is a key component in the magnetic circuit of machines like motors and generators.
- It provides a low-reluctance path for magnetic flux to travel between the field poles and yoke, completing the magnetic loop.
Efficient Magnetic Flux Conduction:
- Made of laminated soft iron or silicon steel to reduce eddy current losses.
- It efficiently conducts the alternating magnetic flux without significant energy losses.
Supports Induced EMF:
- As the armature rotates within the magnetic field, the armature windings (placed in slots on the core) cut through magnetic lines of force, inducing an electromotive force (EMF).
Mechanical Structure:
- It also serves as a mechanical support for the conductors/windings.
