🔍 Key Concepts

• Compare what an across-the-line starter looks like versus a reduced-voltage starter in a schematic (how many contactors/paths between line and motor). • Look at the motor symbol and leads: what is usually shown for a squirrel‑cage induction motor versus a wound‑rotor or synchronous motor (extra windings, slip rings, or field excitation). • Notice whether there are any components that go in series with the motor only during starting, such as starting resistors, autotransformers, or reactors.

💭 Think About

• Count how many main contactors or switching paths are between L1–L3 and T1–T3. Does the motor ever see anything other than full line voltage when the contactor M is closed? • Ask yourself: if this were a wound‑rotor or synchronous motor, what additional parts would you expect to see connected to the rotor or field, and do you see them here? • Focus on the labels around the motor symbol. Are there separate rotor circuits or DC excitation shown, or just three stator leads from a standard induction motor?

✅ Before You Answer

• Verify whether there is a single main contactor directly connecting the line to the motor (typical of across‑the‑line starting). • Check if there are no separate rotor resistors, slip rings, or field excitation circuits drawn anywhere in the diagram (which would rule out some options). • Confirm that there are no autotransformers or series starting resistors in the power path to the motor, which would indicate reduced‑voltage starting.
