🔍 Key Concepts

• Identify that figure A shows a 3‑phase AC motor mechanically driving a DC generator, which in turn supplies a DC motor • Remember the classic DC speed control system that uses an M‑G set (motor‑generator set) to vary the DC motor’s armature voltage via the generator field • Contrast this with more modern systems that use solid‑state (thyristor) rectifiers without a rotating DC generator

💭 Think About

• Look at how the DC motor in figure A receives its power: is it coming directly from rectified AC, or from a separate DC generator driven by an AC motor? • Which historical DC speed control system is best known for using an AC motor, DC generator, and controlled generator field to vary the DC motor’s speed? • Among the choices, which name is associated with an older, rotating machinery type of control system rather than an electronics manufacturer or specific brand of converter?

✅ Before You Answer

• Verify that the circuit in figure A includes a 3‑phase AC motor mechanically coupled to a DC generator (M‑G set) feeding the DC motor armature • Confirm that speed is controlled by adjusting the field of the DC generator, not by directly chopping or rectifying the armature supply with solid‑state devices • Match the method’s description: classic motor‑generator DC speed control system — then choose the option historically linked to that system name
