A major percentage of the global electricity is consumed by electric motors. Electric motors are the soul of the industry and they are responsible for running everything from pumps, conveyors, drive compressors, fans, drills, blowers, mixers and many more things. Hence, appropriate selection of the electric motor for your application is very crucial.
There are certain criteria to be borne in mind when it comes selecting the electric motor for your application. There are basically three categories into which the electric motors fall and they are:
- Synchronous motor
- AC asynchronous motor
- Stepper motor
You have to know exactly the requirements of your application as this will help to make the right choice among the three categories. For example, for an application requiring a continuous run of the motor with minimum gear changes the best choice forms the asynchronous motor. Synchronous motors are best suited for dynamic applications and stepper motors are a right fit for applications needing precise positioning. Choosing a reputed brand is the way to go and in this context, CG electric motors take top place in the listing of good electric motors.
As far as technical specifications go, the power, speed and torque of the motor will be important considerations for your choice. The space occupied by the motor and its mounting system is another aspect that has to be considered. While deciding the motor solidity and measurements, the industrial environment of the application also has to be taken into account as that determines the type of electric motor to choose. For example, if the industrial environment of the application is hazardous then the best fit of the electric motor in this context is the flame proof motor. These motors can resist the impact of an internal explosion and prevent the spread of the resulting fire outside the enclosure. Bharat Bijlee flame proof motors are one of the reputed brands in this respect and their products run for long times to come.
Another factor that has assumed importance in recent times with regard to electric motors is their energy efficiency. Energy efficient motors are the preferred choice for all applications due to the benefit of lower energy costs incurred by their use. Since, electric motors are the largest consumers of electricity in the world it is essential that emphasis is placed on the use of energy efficient motors.
Certain standards have been decided by international bodies to determine the energy efficiency of electric motors. The International Electrotechnical Commission has determined three energy efficiency levels known by the IE code. IE1 stands for standard efficiency while IE2 for high efficiency and IE3 for premium efficiency. A lot of countries use national standards alongside using the international standard for reference. The minimum standard level set by every country’s government differs from one another. India has set the national standard at level IE2 since 2012. In this context, Bharat Bijlee IE2 energy efficient motors are very relevant and need to be incorporated by as many of the industrial applications as possible. Most of the reputed brands keep energy efficiency as a top essentiality in their products and hence sourcing products from such manufacturers becomes the need of the hour!
