Motors are used in every industry and every automation engineer has to deal with motors while working in plants and industries. Most of us have to install and commission the VFD panels and have to feed the motor name plate data in the VFD. But most of the automation engineer are unaware of the meaning of different motor parameters. In this post we will see the meaning of some of the frequently used motor terms.
Frequently Occurring Motor Terms Meanings:-
We all know that the every motor has AMPS rating on its name plate , generally there are three types of AMPS that are related to motor viz full load amps, locked rotor amps and service factor amps. Let us understand the meaning of all these three terms.
Full Load Amps :- As it is very clear from the name , it means the amount of current that motor can withdraw under the full load conditions or under the requirement of full torque.
Locked Rotor Amps :- This AMPS is also known as Starting Inrush current , it refers the amount of current that motor can take under the full voltage starting conditions. We all know that when a motor is connected in DOL then motor takes much more current then its rated current , so Locked Rotor Amps refer to that only.
One other Motor term that is very less common is "CODE LETTER" - it is just the indication of the amount of the inrush current required by motor under full voltage starting.
After studying these motor terms we are now familiar with the common AMPS related words with motors. In the coming days we will discuss more about the other useful and frequently used motor terms , in case you have any doubt you can write to us in the comment section.
