🔍 Key Concepts

• Motor-generator (M-G) set: understand which machines are on the same shaft in an M-G set • Difference between a DC generator and a DC motor in this diagram • How mechanical drive is shown versus electrical connections in the illustration

💭 Think About

• In figure A, look closely at which two machines are drawn together and labeled as the M-G set. Which one is clearly marked as the three-phase motor, and which as the DC machine? • Ask yourself: when we say the three-phase motor ‘mechanically drives’ something, does it drive an electrical part (field or armature winding) directly, or an entire rotating machine that contains those parts? • Trace the power flow: from 3~ supply, to the three-phase motor, then to what component before power reaches the DC motor on the load shaft?

✅ Before You Answer

• Identify the common shaft in the M-G set and see which machine(s) are mounted on it • Confirm which device in the options is a separate rotating machine versus just a winding or component inside a machine • Verify that the element being ‘mechanically driven’ must be the unit that converts mechanical power back to DC electrical power for the DC motor
