What should I do if the generator wind guide is loose?

1. Tighten the nacelle cover fixing bolts 2. Readjust the coaxiality of the wind turbine shaft and the speed multiplier, and tighten the fixing bolts firmly; if the bearing is damaged, replace the bearing and reinstall the bearing seat 3. Adjust the coaxiality of the speed multiplier and tighten its fixing screws; remove the speed multiplier, replace the bearings and oil seals and reinstall the speed multiplier 4. Reattach the brake and adjust the brake pad clearance 5. Readjust the coaxiality of the generator and firmly tighten the mounting bolts 6. Replace Coupling

Where is this motorcycle generator?

Commonly used cooling methods for turbogenerators are:

(1) Air cooling. It is divided into open air cooling and closed circulation air cooling. So-called open-air cooling consists of the fact thatn ordinary small generators, the generator fan draws cold air into the engine from the factory building, cools each part, then exhausts it out of the machine. Closed cycle air cooling is used in large and medium sized generators. After the cooling air exits the generator, it is conducted under the machine pit. After being cooled by a set of air coolers, it is driven into the engine by one. fan. This air always circulates inside to keep the machine clean.

(2) Water cooling. Generally, it is internal double water cooling, that is, the conductors of the stator winding and the rotor excitation winding are hollow, the water from Cooling passes inside the conductors and the stator bore is always cooled by air. Although the cooling efficiency is high, the interior of the conducteur is prone to scaling and clogging.

(3) Hydrogen cooling. It is divided into two cooling methods: external hydrogen cooling and hydrogen water cooling. External hydrogen cooling is the same as air cooling, except the cooling medium changes from air to hydrogen, but the hydrogen cooler is inside the machine. The difference between water-hydrogen cooling and hydrogen cooling is that the cooling water passes inside the stator winding conductor, and the rest is the same as external hydrogen cooling.

Inside the left engine cover.

This type of curved beam motorcycle generator consists of a stator coil and a rotor magnet. The stator coil is installed on the magneto cover and the rotor is installed on the left end of the crankshaft.

The dietengine is high, usually above 5,000 rpm. The power per liter (effective power output per liter of engine displacement) is large, generally around 60 kilowatts/liter, which shows that the motorcycle engine is very reinforced and the engine displacement is small.

In order to ensure engine cooling at low vehicle speeds and before starting, high-power motorcycle engines adopt a forced air cooling method that installs fans and air ducts and uses forced air to blow the cooling fins.

Detailed information:

When the generator is connected to a symmetrical load, the armature winding The three-phase current in the motor will produce another rotating magnetic field, called the armature reaction magnetic field. Its speed is exactly equal to the rotor speed and the two rotate in syncrone.

The armature reaction magnetic field and the excitation magnetic field of the synchronous generator rotor can be approximately considered to be distributed according to the sinusoidal law. The spatial phase difference between them depends on the temporal phase difference between the no-load electromotive force E0 and the armature current I. The magnetic field of the armature reaction is also related to the negative magnetic field.related to the situation loading. When the generator load is inductive, the armature reaction magnetic field acts as a demagnetizer, which will cause the generator voltage to decrease; when the load is capacitive, the armature reaction magnetic field acts as a magnetizer, which will reduce the generator voltage; the generator output voltage increases.
