An AC motor, also known as an alternating current motor, is a type of electric motor that runs on AC power. It converts electrical energy into mechanical energy, allowing it to perform a wide range of applications across various industries. The structure of an AC motor consists of several key components, including a stator, rotor, and bearings. The stator contains coils that are energized with AC power, creating a rotating magnetic field. The rotor, also known as the armature, rotates within this magnetic field, generating torque to drive the motor’s mechanical load. AC motors find extensive use in industrial and commercial applications, such as powering pumps, compressors, fans, conveyors, and many other machines that require continuous and efficient operation. This introduction will further explore the structure and application of AC motors, shedding light on how they function and their significance in various industries.
AC motors are often used for treadmills or ceiling fans, with an average lifespan of up to 10 years. So what exactly is an AC motor and what is the structure of this motor? Please join Thptlaihoa.edu.vn to learn about this issue right in the article below!
What is an AC motor?
An AC motor is a type of electric motor, commonly known as an AC motor. This motor is expanded by alternating current and is quite cheap. Currently, there are many treadmills and ceiling fans on the market that use AC motors.

1.1. Advantages of AC . motor
The outstanding features of AC motors that make many people choose equipment operated by this type of motor are:
- Has a reasonable price and is more commonly used than DC motors.
- While DC motors can only use a control device to operate, AC motors have more ways of working such as using wall switches, pull cords, potentiometers, control devices, etc.
- More designs and styles than DC motors.

1.2. Disadvantages of AC . motor
Besides the above advantages, AC motors also have some disadvantages when compared to DC motors such as:
- AC motors are operated by bidirectional current, so they have a slow rotation speed.
- Consumes more power.
- AC motors operate for about 10 years, so they have a lower service life than DC motors (about 15 years of operation).
Devices powered by AC motors consume more power than DC motors
AC motor classification
AC motor is divided into 2 types including 3-phase AC motor and 1-phase AC motor. Specifically:
2.1. 3 phase AC motor
The rotating magnetic field of a 3-phase AC motor is created by passing a three-phase current into three electromagnets that are spaced apart on a circle. The windings of this motor are the same as in a three-phase generator. However, for electric motors, current is brought from the outside into coils 1, 2, 3.
When the motor is connected to a three-phase network, the stator will create a rotating magnetic field that causes the rotor to rotate on the shaft. Next, the shaft transmits the rotation of the rotor outward to operate tools or other moving mechanisms.
3 phase AC motor
2.2. AC motor 1 phase
The stator of the AC motor 1 is connected by placing two windings at an angle apart, using one wire directly connected to the mains and the other connected to the network through a capacitor. At this time, the two currents in the two coils will be out of phase and create a rotating field.
Small capacity single phase AC motor. Therefore, people can only use this motor in household appliances such as electric fans, vacuum cleaners or water pumps, etc.
Single phase AC motor commonly used in vacuum cleaners
Structure of AC . motor
AC motor is composed of two main parts:
3.1. Stator
In the stator unit there are only windings of three power phases. These coils are wound on the iron core of a ring to create a rotating magnetic field.
The stator unit has only windings of three power phases
3.2. Rotor
The design of the rotor resembles a cylinder, acting as a coil wound on a steel core. Thanks to the action of the permanent magnet, the reluctance convex, the DC or AC coils will generate the rotor magnetic field.

Application of AC . motor
AC motors are widely used in today’s life with many fields such as:
- Civil: Used in small motors of microwave ovens to move rotating discs, washing machines, electric fans or treadmills,…
- Industry: Making machine components in heavy or light industry, mining, oil, industrial machinery, electric crane,…
- Information technology: Used in hard drives, optical drives of computers.

In conclusion, an AC motor, or alternating current motor, is a type of electrical motor that is widely used in various applications. It consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part. The stator is composed of a series of electromagnets that generate a rotating magnetic field when an alternating current is supplied to them. This magnetic field induces a current in the rotor, causing it to rotate.
AC motors have numerous applications in industries and households. They are commonly used in appliances such as refrigerators, air conditioners, washing machines, and fans, as well as in industrial machinery, pumps, and conveyors. They are preferred over DC motors in many cases due to their simplicity, reliability, and ease of control. AC motors are capable of providing high torque at low speeds, making them suitable for heavy-duty applications.
The structure and design of AC motors allow for efficient conversion of electrical energy into mechanical energy, making them an essential component in many devices and systems. Their ability to run on AC power, which is readily available in most places, makes them widely accessible and convenient. Additionally, advancements in motor technology have led to the development of more energy-efficient AC motors, contributing to the overall energy efficiency and sustainability of various applications.
Overall, the AC motor is a fundamental and versatile device that plays a crucial role in modern society. Its simple structure, wide range of applications, and energy efficiency make it a preferred choice for many industries and households. As technology continues to evolve, the AC motor is likely to further advance, enabling more efficient and sustainable power solutions for the future.
