Study Notes
Electric Machines
- The general term for machines using electromagnetic forces in electrical engineering is electric machines.
Electric Generators
- Electric generators convert mechanical energy into electrical energy.
Electric Power Generation
- About 95% of all electric power on Earth is produced by synchronous machines.
Transformers
- The role of transformers in the context of electric machines is to change the voltage of an alternating current (AC) electrical signal.
Electric Generators Analogy
- The function of an electric generator is analogous to a water pump, where mechanical energy is converted into electrical energy, just as a water pump converts mechanical energy into hydraulic energy.
