Motors for Compressors

If a name could be enough to understand a motor, it would probably be named asynchronous electric motors for compressors. Isn’t it? Don’t you know already that it’s an electric motor with some asynchronous movement? The activity happens in the motor’s rotor, but other than that, you have got the idea right. It is a very robust and incredibly reliable machine and has many applications in various industries.

In terms of the scientific definition, the asynchronous electric motor for compressors is a machine that works only with the alternating current. It usually takes its power from the induced energy in the electromagnetic field. Therefore, it is also known as the induction motor.

In this design, the stator can induce a current in the rotating field, making it impossible to synchronize the movement. It is a more classic type of electric motor. Although more efficient synchronous motors for compressors are available, many industries still rely on asynchronous motors for their incredible power, versatility, and longevity.

Why Are Asynchronous Electric Motors Best For Compressors?

The asynchronous motors, the other name is the induction motor. This motor is running by the principle of the electromagnetic induction theory.AC induction motor is known by the name of the asynchronous electric motor. 

The changes in the applied voltage do not affect the torque of the AC induction motor. So when you are looking through the compressor’s purpose, you will see the compressor is working based on the torque speed. And for the asynchronous electric motors, the applied voltage does not affect the torque speed. This is the reason asynchronous motors for compressors are the best option.

Let’s look at the constructional structure of the asynchronous motors and the advantages of using them.

The Construction And The Structure Of Asynchronous Motors

The Construction And The Structure Of Asynchronous Motors

The principle theory of asynchronous motors for compressors is pretty similar to the synchronous motors functioning process. There is a fundamental exception, however. Conduction is not a source of electric power for the rotor of an induction motor, but it is in a synchronous motor. The induction motor also doesn’t come with anything external to wind up the rotor.

In terms of constructions, asynchronous motors don’t use any magnets. Instead, it creates a magnetic field by connecting its phases to the coil. To make the induced voltage, it needs to apply the magnetic field to pass through the rotor. The design makes it vary the speed between the rotor and the magnetic field. It means that the slip value in these motors is not null and can not be changed.

The Advantages Of Using Asynchronous Motors For Compressors

The Advantages Of Using Asynchronous Motors For Compressors

Asynchronous motors for compressors application are pretty robust but little efficient. But for the compressor, this powerful application process is going to make the machine performance outstanding.

Yes, asynchronous motors are relatively less efficient than synchronous motors. It still has many applications for its unique benefits. 

Here are some advantages of using the asynchronous motor for compressors

  • It is a self-starting motor that doesn’t require any outside operator. It also costs way less than more efficient options.
  • The speed of the motor also decreases as the load increases, which makes it useful for specific applications. It can be more efficient than other motors in some partial-load operations, making it even more versatile.
  • Among the many industrial applications, industries like paper mills, petrochemical pumps, wind power turbines, blowers and ventilation manufacturing industries, and textile mills seem to benefit the most from induction motors. As the compressors and rotors of ceiling fans need self-starting motors, the manufacturers of home appliances like fans and refrigerators also rely on asynchronous motors a lot. 
  • Many industrial types of machinery like heavy-duty cranes, conveyor systems, oil pumps, and leather transporters come with induction motors to power their heavy-lifting.


Asynchronous motor’s biggest advantage is for the robust application process. This machine is very efficient for industrial use. The asynchronous motors for compressors are very widely used in the textile industry and other domestic purposes. The main advantage is the voltage ups and downs do not affect the machine’s speed and functionality.

When you consider the unmatched reliability of asynchronous motors and add them to the many benefits, you will know why almost 90% of the electric motors applications are these motors. To learn more, please visit
