GENERAL PURPOSE OF ELECTRIC DRIVE
Used in domestic as well as industrial application.
Used in pump, fan and compressor in industry
Used for mechanical load
Used in heating, ventilation and air conditioning system.
Used in tractions.
NECCESITY OF ENERGY CONSERVATION
To meet increasing demand of electrical power
It is necessary to minimize energy consumption.
It also necessary to reduce load sheading.
To avoid unbalanced of power system
To reduced energy cost.
LOSSES IN ELECTRICAL DRIVES SYSTEM
losses in winding,
i.e. copper losses & core losses
electrical transmission losses
mechanical losses
conversion losses
