AC machines can be considered as the most used in comparison to DC motors, taking into account relevant factors. As an example, the simpler construction and maintenance can be highlighted, as well as having a longer life, since for the same power as a DC motor, the engine becomes considerably more economical.
The electric motor basically consists of a machine whose main purpose is to transform electric energy into mechanical energy. The electric motor is considered the most used of all other existing types, by combining the advantages of using electric power, which has low cost, easy transportation and cleaning and simplicity of command, since it has a simple construction, low cost, wide adaptation versatility of the most diverse types, in addition to gaining better yields.
Therefore, DC motors and alternating current can be applied to simplified equipment such as electric traction for batteries, forklifts, buses, trucks, household appliances, portable machines and tools in the case of direct current, for example. AC motors can be found in water pumps, compressors and machines used in industry in general.
