I have encountered this problem before:
At that time it was caused by overheating and stuck motor bearings.
I think your reason maybe there are too many. a lot of damage in some places.
New things are prone to these problems, they must first go through a period of friction. it seems dead, it's friction. The reason is that it is too big.
Add a little oil to the places where oil needs to be added, then remove the fan blades and let them idle for half a hour.
You should be fine
The generator cannot produce electricity if it is idling.
Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines to convert water flow, water flow'air. , fuel combustion or atomic nuclei The energy produced by fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
