Principles of CA

Electric synchronous AC motors are basically operated at a fixed speed, used only in cases where high power is required or when constant speed is required. Induction motors usually operate at a constant speed, which can vary subtly with the mechanical load applied to the shaft. Due to its great simplicity, ruggedness and low cost, the induction motor is by far the most commercialized and used of all other manufactured ones, noting that they also become suitable for almost all types of driven machines, found in practice.

Nowadays, unlike in the past, it is feasible to perform the speed control of the induction motors with the help of frequency inverter devices. Alternating current motors are considered to be the most sought after for different purposes, and one of the many existing reasons that directly contribute to this fact is based on the continuous distribution of electrical energy, which can usually be realized by alternating current . The most relevant categories of alternating current motors are synchronous motors and induction motors.
