The frame, the core, the winding, and the end plates are parts of which machine component?

• A. Rotor.
• B. Stator.
• C. Alternator.
• D. Induction Motor.

Answer: (B)

The stationary part of an electric machine is responsible for creating the magnetic field that the rotor will respond to, so the parts listed—frame, core, winding, and end plates—are all features of that stationary assembly. The frame provides the outer housing and mounting structure, the core is the laminated iron that guides the magnetic flux, the winding carries the AC current to produce the magnetic field, and the end plates cap and support the assembly, helping align everything inside the frame. The rotor, which sits inside this housing and turns, is a separate component and contains its own core and, in some designs, windings or bars, but it does not include the outer frame or the end plates. Therefore, these parts together describe the stator.
