🔍 Key Concepts

• Trace the power circuit from L1–L3 to T1–T3 and notice what components are in series with the motor during starting. • Compare where the resistors (the zig‑zag symbols) are located: are they in the line side (primary) or in the rotor/secondary side of the motor? • Ask yourself whether this drawing shows any voltage‑changing transformer in the motor circuit itself, or just a control transformer.

💭 Think About

• When the motor first starts, what current path does it take through each phase, and what happens later when the 1A contacts change state? • If this were an autotransformer starter, what extra windings and tap connections between line and motor would you expect to see in the power circuit? • If it were an across‑the‑line starter, would there be any extra series components between the line contactor (M) and the motor leads T1–T3?

✅ Before You Answer

• Verify exactly where the resistors are inserted in the circuit: between L1–L3 and the motor, or in a separate rotor/secondary circuit. • Confirm whether the only transformer in the diagram is a small control power transformer, not a three‑phase autotransformer feeding the motor. • Check if the motor is ultimately connected directly across the line after starting, and whether any starting components (resistors or transformer windings) are bypassed at that point.
