1. The engine is not well lubricated. Therefore, the motor cannot move once the fan blades are installed. Remove the fan blades, plug in the power and the shaft can rotate.
2. The fan is overheating. Overheating of the motor will also cause the load capacity of the motor to deteriorate and the active power of the motor to decrease, resulting in the inability to drive the load.
3. If the electric fan is used for a long time, the motor will wear out. Once the motor sleeve is worn out, it is easy to burn. If the motor is used for a long time, the internal resistance of the motor will also increase and the load capacity will decrease, resulting in the inability to rotate the fan blades.
4. The capacity of the starting capacitor becomes smaller. The parameters are written on the nameplate. Over time, capacity decreasesra, which will result in lower motor starting torque and inability to drive the load. Remove the capacitor and replace it with a new one, which should be 20% larger than the original one.
The wind turbine blades do not turn. What is the reason?
The faster the wind turbine spins, the more electricity it generates. Note that the power output of a generator can be roughly thought of as proportional to the product of speed and torque. The torque here is the electromagnetic torque obtained by the excitation of the generator. The torque is so great that the wind cannot move the turbine. At this time, the rotation speed is 0, the torque is very large, and the power output is 0. When the torque is zero, the speed accelerates to a very high level. It's actually a flying car, which is extremely dangerous. Since the electromagnetic torque is 0, the output power is equal to 0.gale at 0. Power is 0 at both extremes, so there is an optimal speed that maximizes power output.
The ideal value of this optimal speed can be calculated from Baez's theory, which is the ratio between the linear speed of the blade tip and the wind speed in front of the wheel. At a certain wind speed, there is a non-linear relationship between fan power and blade tip speed ratio. Through the theoretical derivation, the optimal peak speed ratio for each wind speed can be calculated. A wind turbine is a device that converts wind energy into mechanical energy, then operates machines and finally generates alternating current. In fact, wind energy can also be considered solar energy because it is also used to generate electricity and is not harmful to our environment.
It is capable of producing a largende amount of energy due to its internal structure, rather than depending on the external rotation speed of the blade. It's better to spin your own windmill faster. gear inside that turns silently. The windmill rotates at a speed of 20 to 30 times per minute, and the wind is not enough. That doesn't mean it can't spin faster. This is due to the weight and length of the blades. you see it from a distance, don't think it's big, in fact it is. The blade is more than 20 meters long, and the weight can be imagined. If you turn too fast it will put a lot of pressure on the. base. If a generator collapses or its blades break, it could cause an accident and injure nearby residents. If it spins slowly, there will be no such thing. This will ensure that the windmill blades will not be injured, prone to accidents, and will not affect the effectiveness of their production of energy. After all, there's a little engine hidden inside! it, even if the strong wind outside turns very slowly. There are reduction gears and gears inside, and its speed will also increase by about fifty times, basically maintaining a speed of about fifteen hundred revolutions per minute.
Wind Power PosterIf the generator does not turn even in strong wind, the problem may be as follows:
1. Check if the generator's 3-phase AC line is shorted
2. . If the fan blades are installed backwards
3. Is the engine burned out
4. Problems with the bearings
Problems with the other two fans? the original poster:
When people don't feel any wind on the ground but the blades are spinning very fast, it's normal, because people on the ground certainly feel that there is no of wind, and when the fan is several meters high, the directionwind will be different. The main thing is to check if the leaves are visibly windy, it's normal for the fan to spin so slowly, but the other fan doesn't spin how far. the distance between the two fans? If it is too close, it is normal, because two fans cannot be installed too close, which will affect its overall effect. Additionally, the owner should be aware that there should not be any great height. buildings around when installing the fan, and it is better to install it in an open area.
That's all, the original poster, please check if the above situation exists< /p>
