Introduction of electrical

motors and its principle

Now a days the electricity is the major part in universe such that the

electricity can be use and generates in the following waysHydro power generation Thermal power generationNuclear power generation

The conversion of electrical energy to mechanicalWe are using two types of motors

Single phase induction motor3-phase induction motorNow a days in industries and other electrical applications we areusing70% of electrical loadsBasic principle of electrical motors : the basic principle is to convertthe electrical energy mechanical energy is called motor.
