While both transformers and induction motors are fundamental components in electrical machines and rely on electromagnetic induction, they serve very different purposes and operate in distinct ways. 🔌 Transformer: A static device (no moving parts). Used to transfer electrical energy between two or more circuits through mutual induction. Operates only on AC (Alternating Current). Changes voltage levels (step-up or step-down) without changing frequency. Key Features: High efficiency (up to ~99%) Used in power transmission and distribution No mechanical output – purely electrical ⚙️ Induction Motor: A rotating electrical machine. Converts electrical energy into mechanical energy. Works on the principle of rotating magnetic fields and induced currents. Comes in single-phase and three-phase types. Key Features: Common in industrial and household applications (fans, pumps, conveyors) Rotor rotates due to magnetic induction from stator Mechanical output for driving loads ⚖️ Comparison Table: Feature Transformer Induction Motor Type Static machine Rotating machine Function Voltage conversion Mechanical power generation Output Electrical energy Mechanical energy Moving Parts None Yes (rotor rotates) Energy Conversion Electrical → Electrical Electrical → Mechanical Applications Power grids, chargers, UPS Motors in fans, pumps, elevators
