Electric machines are devices that convert electrical energy into mechanical energy or vice versa. They are commonly used in various applications, such as powering appliances, vehicles, and industrial equipment. The two main types of electric machines are electric motors, which convert electrical energy into motion, and generators, which convert mechanical energy into electrical energy. These machines operate based on electromagnetic principles, utilizing components like rotors, stators, and windings. Electric machines are essential in modern technology, contributing to energy efficiency and automation in numerous sectors, including transportation, manufacturing, and renewable energy systems.
