The electric motor sees its birth in the late 18th century. However, it was Nikola Tesla in 1888 who patented the three-phase system which brought the use of the engine to the industrial field. Later in 1934 the first transistors were born which revolutionized the world of power electronics. Only in 1983, however, was the first IGBT (Insulated Gate Bipolar Transistor) introduced, which will be widely used in the control of synchronous and asynchronous motors, within the first VFD (Variable Frequency Drive). From there the world saw further inventions, such as stepper (or "stepper") motors, brushless motors and other products that revolutionized the industrial and non-industrial world.
