How does an AC motor work?

2022-11-15 13:39:58

An AC motor mainly consists of an electromagnetic winding or distributed stator winding that can generate a magnetic field and a rotating armature or rotor. Inside the stator, there is a solid metal shaft, a coil, a squirrel cage made of metal strips and interconnects, or some other freely rotating metal part that conducts electricity. The rotor suspended in the magnetic field is an electrical conductor. The constant rotation of the stator and the rotor will generate a magnetic field. The stator windings that generate the rotating magnetic field are generated by alternating current. The magnetic field is constantly changing, and according to Faraday's law, the magnetic field creates a current within the rotor. In AC motors, the windings are used as armature and field windings. When the stator is connected to the AC power flux, an air gap is created, which causes the flux to rotate at a fixed synchronous speed, creating a voltage in the stator and rotor windings.

What is an AC motor?

An ac motor is a motor that utilizes the phenomenon of electromagnetic induction and consists of a stator and a coil that is supplied with alternating current to convert the current into mechanical energy. Unlike DC, which only moves in one direction, the current inside an AC motor periodically reverses direction and continuously changes its magnitude over time. The stator is the stationary part of the motor and the rotor is the rotating part. AC motors can be single-phase or three-phase, and three-phase motors are mainly used for high-capacity power conversion. Single-phase AC motors for small power conversion.

Conclusion

An AC motor is a low-cost, high-efficiency machine. Most of the appliances, equipment, and tools we use every day are powered by AC motors, and even anything that can be plugged in may be powered by AC motors, which shows that AC motors can be used in a wide range of applications.
