![]() The invention of the induction motor is without a doubt, one of the greatest achievements in harnessing electricity to power our lives. Even though apparently the Italian inventor first developed this motor in 1885, Nikola Tesla was first to file the patent in 1888. ![]() It has been invented by two independent researchers - the one and only Nikola Tesla and Galileo Ferraris. The asynchronous induction motor isn’t something new. Asynchronous induction motor - Brief history lesson Is this variety of designs relevant for the electric motors as well? How many types of motors do we have in e-mobility? The answer is just 3 main ones. In the quest for improving efficiency, many designs have been introduced throughout automotive history by engineers. The question that almost automatically arises is, why do we have so many internal combustion engine designs and concepts? The answer is simple - because none of them is good enough from an efficiency standpoint. Naturally aspirated engines, turbocharged engines, direct injection, indirect injection, or both direct and indirect injection! Petrol, diesel, CNG, LPG, Atkinson cycle, Miller cycle, Budack cycle, Diesel and Otto cycle (See Mazda Skyactiv-X engine), fixed geometry turbo, variable geometry turbo, twin-scroll turbo, variable camshaft timing… the list goes on. If you are interested in performing a deep dive in internal combustion engine technology, you must be prepared to be bombarded with many different concepts.
