Question

3 how is the stator constructed? a massive iron bundle. a stack of laminated plates with slots. a plastic casing with slots.

Explanation:

To determine the correct construction of a stator (in electrical machines, e.g., motors/generators), we analyze each option:

• A massive iron bundle: Incorrect. Stators use laminated plates (not massive iron) to reduce eddy current losses.
• A stack of laminated plates with slots: Correct. Stators are typically made by stacking thin, insulated (laminated) iron plates (to minimize eddy currents) with slots to hold windings.
• A plastic casing with slots: Incorrect. Stators require magnetic material (iron/steel laminations), not plastic, for magnetic flux paths.

Answer:

B. A stack of laminated plates with slots.

(Note: The original options’ checkmarks may be errors; the correct technical answer for stator construction is a stack of laminated iron plates with slots. The “massive iron bundle” and “plastic casing” are incorrect for standard stator design.)
