An AC motor is an electric motor that produces mechanical energy using alternating current. From small home appliances to large industrial pieces of equipment, an AC motor is used to generate a secure and stable energy cycle. AC motors are flexible and versatile to different requirements, which makes them a suitable choice for most industry applications.
In contrast to DC motors that operate on a direct power source, an AC motor, or Alternating current motor, utilises a variable current to create mechanical motion. An AC motor consists of a rotating part called a rotor and a stable stationary component called a stator.
You can choose from a single-phase and a three-phase AC motor for a wide range of applications. However, based on the power source and speed, AC motor is classified into two categories:
The main principle of AC motors is based on electromagnetic induction. It has a basic AC motor consisting of a wire coil and two magnets near a shaft. By providing alternating current to the wire coil, it transforms into an electromagnet that generates a magnetic field. The continuous creation of magnetic fields helps produce stable electricity for home appliances, tools and large-scale machinery.
AC motors are one of the most common engines used in the world. They offer multi-fold benefits at every level of production or process.
As an industry and household favourite, there are a wide range of uses of AC motor in a variety of industries:
The flexibility of variable speed and power allows AC motors, especially with Variable Frequency Drives, to be a safe and reliable energy engine for household appliances. From large appliances like washing machines and refrigerators to smaller fans, it can help power everything.
With effortless usage and noise-free application, AC motors are a staple for the food and beverage industry, where there is a need for consistent speed and high torque for long hours. They are used to run machinery such as mixers, conveyor belts, packaging machines and others.
HVAC refers to the equipment that helps produce the desired temperature in a room, such as AC, fans, coolers, heaters, etc. AC motors provide convenient adaptability in temperature management and assist in airflow regulation, making them essential components of HVAC systems. They help run compressors, high-power fans and pumps.
The rise in AC motor technology has directly influenced the growth of the automotive industry, especially electric vehicles. AC motors aid in windshield vipers, regulate speed, cooling fans and power windows.
Manufacturing industries require engines that can run their heavy-duty machines and robots for fast and high-volume production. AC motors provide high-volume torque that helps power machines such as conveyor belts and robotic arms. It offers continuity and an easy-to-manage application that saves costs in the long run.
The durability and ability to bear long-term wear and tear make AC motors a popular choice for farmers and the agricultural industry. They help run various pieces of machinery, such as irrigation pumps, grain elevators and ventilation systems. They also offer the added benefit of minimal repair and reduced energy usage.
AC motors are an industry favourite due to their strong design, stable output and flexible torque volume. And, if you’re looking to invest in an authentic AC motor for your business or household usage, look no further than L&T-SuFin.

The most commonly used AC motors are three-phase systems, particularly induction AC motors. They offer stability, flexible output and durability.
The speed of the AC motor is determined by the frequency of the power supply and the number of poles. Traditionally, a double-poled AC motor operating at 60 Hz will run approximately 3600 rpm. With four poles, it will boost upto 1800 rpm.
The basic principle that AC motors work on is electromagnetic induction. When AC flows through the stator, it creates a rotating magnetic field, which in turn generates electricity or mechanical energy.
AC motors use Faraday’s Law of Electromagnetic Induction, which talks about how a rotating magnetic field can generate electric current in the rotor.
