A motor generator (M-G) set alludes to a composite gadget comprising of a motor and a generator mechanically coupled through the regular shaft. Essentially a motor generator set is a framework where a motor and a generator are associated or fairly put in a solitary circuit. It is a gadget used to change over electrical force starting with one frame then onto the next. That is for the most part it changes over electrical energy to some other sort of force.
Motor generator set are additionally used to change over voltage, stage and recurrence of force. They additionally discover application in segregation of electrical burdens from the supply line. Here is a pictorial representation of a MG set. Here a motor and a generator are coupled together utilizing a solitary shaft; they are twisted around a solitary rotor. Important condition for coupling is that appraised pace of both motor and generator ought to be same.
Working Principle: From the above chart we can see that in a normal motor generator set, the force is offered remotely to a motor and accordingly the pole of the motor turns the rotor of the generator. That implies, motor gets electrical vitality information from the supply line. Its pole pivots and since the generator shaft is mechanically combined with it, the generator additionally gets its mechanical information through shaft. In this way generator likewise makes electrical yield power or at the end of the day generator changes over the mechanical vitality into electrical vitality.
Therefore while the force at the data and in addition yield side is electrical in nature, the force streaming between the machines is in type of mechanical torque. This gives disengagement of theelectrical framework and in addition some buffering of force between the two electrical frameworks.
- AC to DC – This is possible by using a AC motor (induction motor or synchronous motor) and a DC generator.
- DC to AC – This can be accomplished by using a DC motor and an AC generator.
- DC at some voltage level to DC at another voltage level.
- Alternating power at one frequency to Alternating power at another frequency
- Fixed AC voltage to variable or regulated AC voltage
- Single phase AC voltage to 3 phase AC voltage
Presently days motor generator sets have been updated from multiple points of view. Prior these were utilized as a part of the spots where speed regulation is required profoundly like lifts, industrial facilities and so forth. Presently day’s semiconductor gadgets are acting as the motor generator set i.e. with the presentation of force semiconductors gadgets like thyristor or SCR?”>thyristor, GTO, MOSFET and so on motor generator set are supplanted by them. These transformations of force starting with one frame then onto the next can be achieved effortlessly. They are little and conservative in size, misfortunes are less and control is simple.
