# How A 3 Phase Ac Motor Works

By | December 3, 2021

Whether you're a homeowner looking to install a new HVAC system or an engineer studying the physics of electricity, it's important to understand the inner workings of a 3 phase AC motor. A three phase AC motor is an electric motor that runs on alternating current and utilizes three separate phases of power to create a rotating magnetic field. This type of motor is used in a variety of applications, from powering fans and pumps to driving industrial machinery. The following article will discuss how a 3 phase AC motor works and explain some of the advantages of using this type of motor.

At its most basic level, the 3 phase AC motor functions by converting electrical energy into mechanical energy. This can be done through the use of magnets, electrically charged coils, and an arrangement of three separate but connected phases of alternating current. By running different phases of current through these components, a rotating magnetic field is created. As the magnetic field turns, it acts upon the rotor of the motor, causing it to rotate and transfer mechanical energy.

In order to better understand the mechanics of the 3 phase AC motor, it's important to first examine how the alternating current is produced. The source of this current is typically a generator or an inverter, which are connected to three separate phases of power. This three-phase system is then channeled into the motor, where it is converted into a rotating magnetic field. Each of the three phases of current flows through a coil, creating a different magnetic field for each one. When these fields interact with each other, they produce a rotating force that turns the rotor.
