• DC Machines – Construction, armature reaction, commutation, characteristics of generator/motor, speed control, testing (Swinburne’s, Hopkinson’s).
• Transformers – EMF equation, equivalent circuit, regulation, efficiency, auto-transformer, 3-phase connections, parallel operation.
• Induction Motors (3-Phase & 1-Phase) – Rotating magnetic field, torque-slip characteristics, starting methods, speed control, equivalent circuit.
• Synchronous Machines – Alternator construction, voltage regulation (synchronous impedance, MMF, Potier methods), synchronizing, parallel operation, synchronous motor starting/V-curves.
• Special Machines – Stepper, universal, reluctance, hysteresis, permanent magnet, and servo motors (introductory, but exam-relevant).
