All types of Motor & Generators - AC & DC‚ Starters:Induction Motor (3 Phase):The production of a rotating magnetic field (RMF) is essential for the operation of alternating current (a.c.) induction motors. The speed of rotation of an RMF is known as the synchronous speed and this will be governed by the value of the supply frequency and the number of poles wound within each phase winding. Each of the phase windings are 120 electrical degrees apart. Synchronous speed can be calculated using the following

CIRCUIT DIAGRAMME POWER INVERTERS Power inverters are simply DC (direct current) to AC (alternating current) converters - they convert DC energy stored in a battery‚ to the electric current (AC) that your appliances require. An inverter taps current from the public supply when that is on (or‚ alternatively‚ from a power generator)‚ stores that power in its battery bank as DC and converts it to AC when the power supply is gone. That way‚ the inverter provides the power backup you need‚ filling

The cost benefit analysis of Plug In hybrid electric vehicles includes a comparison between the lifetime of the vehicle and the ownership cost. Here the cost of ownership includes the cost of consumption of energy as well as the retail cost‚ but excludes the differences in cost of maintenance. A high cost of 5 USD per gallon of gasoline is assumed for the near term scenario. The cost of consumption of electricity is assumed to be 0.09 USD per Kilowatt-hour.[29] 7.
