Electric motors are indispensable items in the industrial and domestic world and their existence has contributed a great deal towards getting things done easily. The scope of their use is huge as they have touched upon almost every sector of the industry.
The electric motor converts electrical energy into mechanical energy and in the process leads to formation of magnetic fields and these in turn work with conductors transmitting current to create the desired force. The force generated in the above process becomes the basis of functioning of the electric motors. The electric motor comprises of six parts which include the rotor, axis, commutation, brushes, field magnet and DC/AC power supply.
One example of an application requiring electric motors powered by DC supply includes car batteries whereas another requiring motors powered by AC supply include the National Power Grid etc. There are a multitude of applications ranging from small items like an electric toothbrush to colossal machines like cranes and others that use electric motors for their working.
Electric motors are categorized into three categories namely the electrostatic, piezoelectric and magnetic versions. The magnetic version is more commonly used in different applications as compared to the other two categories. Magnetic electric motors are further subdivided into asynchronous and synchronous categories. The magnetic field source in synchronous category comes from permanent magnets. The asynchronous category is also termed as induction motors. Induction motors can be 3 phase induction or single phase induction and each of them are earmarked for specific applications. Features of single phase motors include the start capacitor, single phase poles, manual overload protection, distinctly designed shaft, heavy duty ball bearings and high torque output and all of them help in giving better performance. The 3 phase motors are more suitable in applications needing higher output.
In addition to standard electric motors, the flame proof motors assume significance in hazardous industrial settings. There motors come in top quality encasing and have labels indicating the degree of protection offered. They need to clear stringent standards with regard to insulation ratings, frequency, voltage, temperature class etc.
Electric motors irrespective of their type hold a place of importance in industrial settings and as such they have to be sourced from reputed suppliers who stock trusted and reliable brands. Crompton Greaves electric motors and Crompton Greaves flame proof motors are two trustworthy brands that function effectively for long times. Moreover, they cause less pollution and contribute positively towards a green environment. Trustworthy brands have the stamp of quality from foremost national and international certifying bodies and hence, you are assured of their seamless working.
Besides checking for trustworthy brands you have to consider a few other factors while sourcing your electric motor so that you achieve high levels of energy efficiency. Size of the motor, full-load speed and the electrical resistance offered by the electric motors for sale have to be checked to see that they are in line with your requirements. There are several dealers like Bharat Bijlee electric motor dealers and others who stock a wide variety in order to offer highest levels of customer satisfaction!
