The power supply is a system that starts the clock and goes to the electric motor post where happens the supply of energy and causes the electric motor to work.
The grid may present problems that can be caused by: supply voltage level, voltage imbalance between the phases, power variation and frequency of the presence of harmonics. t279743s 2016 mro supply
The electric motor works optimizing the operation of the rated voltage. Although there tolerance ranges for the electric motor works, the electric motor will operate so that the electric motor does not present failures or drop in your income, because it means that the electric motor will operate at its best.
For the electric induction motor is subjected to voltage above the nominal, which will need to occur an increase in the starting current and this will cause the engine to suffer a considerable reduction in its power.
