Electric generators and motors: An overview
CES Transactions on Electrical Machines and Systems, 2017 Starting with Faraday's law of electromagnetic induction in 1831, electric (electromagnetic) machines have been developed ever since as “assembles” of electric and magnetic coupled circuits that convert mechanical to electrical energy (in generators) and
