Electric motors make it possible to perform different types of movement: fast, precise, continuous, with or without gear shifting, etc. All of these applications require their own motor technology.

First, you must choose between three main groups of electric motors:

The AC asynchronous motor (single-phase or three-phase)

The synchronous motor: DC motor (direct current), brushless, etc.

The stepper motor

In order to choose between these three groups, it is necessary to determine the type of application required as this will influence your choice:

If you want your motor to run continuously and with few gear changes, you should choose an asynchronous motor.

For dynamic applications, it is essential to have a synchronous motor.

Lastly, if you require precise positioning you should choose a stepper motor.

Depending on the movement you require, you will also need to determine the technical specifications and size of the motor:

To determine the technical specifications, it will be necessary to determine the power, torque and speed of the motor.

In order to determine the size, you must know how much space the motor will take up and how it is mounted (i.e.how it will be fixed in the system).

When choosing the dimensions and solidity of the motor you must also take into account the industrial environment that the motor will operate in:

There is a format adapted for every type of environment (explosive, damp, corrosive, high temperature, etc.)

For harsh environments there are motors with reinforced, waterproof, shock-resistant or dirt-resistant casings.

Finally, in recent years, energy efficiency has become an important factor to take into account when choosing a motor:

An electric motor that uses less energy will have a low energy impact, which will reduce its energy cost.
