Before enumerating the advantages and disadvantages between AC and DC gears, we have to make a brief definition of both systems, when we speak of dc we are referring to the electrical charges that flow over a conductor of the shape-invariant, i.e. which do not change their intensity over time. Alternating current behaves differently, which is crucial when you buy gears online, unlike the continuous or direct this if varies its intensity as time goes by, this is given by the electrical loads changing their direction of movement in the driver periodically.
