Both the AC motor and DC motor work very the same in terms of converting electrical into mechanical energy. However, they are designed, built, controlled, and powered in different ways. The most obvious distinction is, of course, their power source. DC motors are powered by direct current like a battery while AC motors are powered by alternating current, hence their names. AC motors are commonly preferred for their increased efficiency and power output while DC motors are opted for their output and speed control.
In addition, an AC motor comes either in single-phase or three-phase types while the DC motor often always comes in single-phase configuration. When it comes to the motor’s construction, DC motors are made with a commutator and brushes while AC motors don’t have brushes, making them so rugged and can last for a long time. An AC motor has several components, including a stator and a rotor. The energy it generates is from the magnetic fields that are generated by the coils around the output shaft. It has been a viable solution for numerous power generation needs due to its efficiency, flexibility and durability.
AC motors come in two different types to choose from and can be used for various range of applications such as water heaters, food service pumps and garden tools and equipment. The first type is the induction AC motor that consists of two electrical assemblies - the rotor assembly and the wound stator. They are deemed to be the most rugged yet simplest electric motor design and are the one of the most commonly used motors available worldwide. The energy required to run the rotor is created through electromagnetic induction produced by the stator winding. The other option is the synchronous motor type. As its name implies, this motor rotates with the same rate as that of its supply current. It consists of the synchronous motors, a rotor and a stator, and is used in a variety of applications.
