Electrical machines are devices that convert electrical energy into mechanical energy or vice versa. They play a crucial role in various applications, from powering household appliances to driving industrial equipment. Common types of electrical machines include motors, which convert electrical energy into motion, and generators, which transform mechanical energy into electrical energy. These machines operate based on electromagnetic principles, utilizing components like coils, magnets, and rotors. Their efficiency and performance are essential for energy management in modern technology, making them vital in sectors such as manufacturing, transportation, and renewable energy systems.
