AC motors are also distinct from DC motors due to the fact most AC motors do not include brushes. This means that maintenance and parts replacement requirements for AC motors are inclined to be considerably decreased, with most consumers typically anticipating a lengthier regular lifespan. In contrast to DC motors, the output velocity of a lot of kinds of AC motors is often decided by inverter control – yet again, we will briefly outline a assortment of prospective variations on the fundamental AC motor design.
