Electric motor is now present in locomotives around 1879

The electric motor has been implemented in electric locomotives around 1879. The electric motor had many advantages compared to steam power, animal power, and also the waterwheel.

However, the high cost in manufacturing the electric motor and also to have a vulnerable switch leeson 175310, made the scientists seek to develop an electric motor to produce a lower cost ma manufacturing, were an electric motor able to withstand the pressure when required and also present a low maintenance cost.

Several researchers worked on the idea of ​​developing a more robust electric motor and among many, the highlight is the Yugoslav Nikola Tesla, the Italian Galileo Ferrarris and Russian Michael von Dolivo-Dobrovolski, because these three researchers have perfected only the electric motor DC, but they have started to work on alternating current.
