In engineering, we simply divide transformer losses into two types of losses: no-load losses and load losses. The technical definition is: when the transformer is operating at no load, there is no load loss, only no load loss. At this time, there is only no-load current (excitation current) in the primary side coil. The resulting losses are all attributed to no-load losses, i.e. excitation losses. Commonly called iron loss (loss), it means that due to the excitation current, a magnetic flux is generated in the iron core, and this magnetic flux produces eddy current loss and hysteresis loss in the iron core. iron core. This is a loss of iron (loss of excitement).
Actually, in technical calculations, the resistance loss caused by the no-load current (of course, its value is very small) in the primary coil is ignored. Only the loss inhe pure iron core is calculated and its value is related to the material and magnetic density of the silicon steel sheet.
A failure. The costs outweigh the benefits, so how much power can such a small generator produce? Let's put it this way: lighting electricity currently costs less than 0.6 yuan per kilowatt. How many years does it take for such a small generator to operate to produce 1 kilowatt of electricity? But the cost of 0.6 yuan cannot build this set of generators.
