Most residential and commercial buildings are not powered by batteries through DC current but through alternating current or AC motor. What makes this motor highly functional is the rotating magnetic field surrounding the outside part of it, which makes up the stator. Inside of this stator is a coil, a loop of wire, a cage comprised of metal bars and interconnections. You can think of the cage as the rotating cages set up for mice to run. There are also other metal parts that freely rotate inside to generate electricity. As for the coils, they are paired in sequence to produce the magnetic field that surrounds the stator.
The stator itself is made of copper wires tightly wound into coils, which are also referred to as the windings. So, how does such a rotating magnetic field enable the AC motor to move? It is basically due to the rotor that serves as the electrical conductor. It is suspended inside the constantly changing magnetic field. This constant rotation is what produces the electric current inside the rotor. This operating principle of the motor has simply grounded upon the laws of electromagnetism that is achieved through the various metal parts inside the motor.
If the electrical conductor is a single piece of metal, it is the famous eddy current that rotates around it but if it is a ring, the current also flows in a loop around it. Whatever is the conductor material, the produced electrical current also generates a magnetic field. With this unique operation, an AC motor is designed to handle a wide range of loads at a consistent speed. But if your specific application for this motor requires high levels of output power, you have to carefully consider which type is most suitable for it.
