First of all, 220V is sufficient to power most household appliances. However, if you find that your permanent magnet DC motor wind turbine cannot power your home appliances, it may be due to the following reasons: Insufficient current: Your generator may not be producing enough current to power the home appliances. You need to check that your generator produces enough current at all wind speeds.
Cable resistance is too high: The cable connecting the generator to the appliance may have too high a resistance, restricting the flow of electricity. You need to check if the cable is intact and if it is damaged or has poor contact.
Capacitance matching problem: Some household appliances require specific capacitors to function properly. You need to check if your devices require share capacityspecific and if your generator creates this capacity.
Insufficient motor power: The permanent magnet DC motor you are using may be too small to operate some larger appliances. You may consider upgrading to a more powerful motor.
What should be added to the output depends on the specific cause of the problem. If this is due to insufficient current, you may need to add a booster device to the generator to increase the output voltage. If the cable resistance is too high, you must replace the cable. If it is a capacitor matching issue, you may need to add appropriate capacitors to the circuit. If the motor power is insufficient, you should replace it with a more powerful motor.
The wind part – it converts wind energy into mechanical energy; the generator part - it converts mechanical energye in electrical energy. Depending on the different structural types used in these two parts of the wind turbine, as well as the different characteristics of the technical solutions they adopt, coupled with their different combinations, wind turbines can be classified into various categories.
1. According to the direction of the main axis of rotation of the fan (i.e. the relative position of the main axis and the ground), it can be divided into: "horizontal axis fan" - the axis of rotation is parallel to the ground and the turbine must change with the direction of the wind. And adjust the position; "vertical axis fan" - the axis of rotation is perpendicular to the ground, the design is relatively simple and the turbine does it. no need to adjust its direction when the wind direction changes.
2. According to the number of blades, they can be divided into “single-blade”, “double-blade”, “three-blade” and “multi-blade” type fans; by many fafactors including air energy efficiency, complexity, cost, noise, aesthetic requirements, etc. Large wind turbines can be made up of 1, 2 or 3 blades. Wind turbines with fewer blades generally require higher rotation speeds to extract energy from the wind and are therefore noisier. And if there are too many blades, they will interact with each other and reduce the efficiency of the system. Currently, three-bladed wind turbines are the norm. From an aesthetic point of view, the 3-blade wind turbine looks more balanced and beautiful.
3. Depending on the direction in which the fan receives the wind, there are "upwind types": the front of the turbine faces the direction of the wind (i.e. it turns into the wind in front of the round). ) and "downwind type" - the wheel Return to the wind direction, two types. The fan in the wind is normal. Some sort of steering device is necessary to maintain the turban facing the wind. The downwind fan can automatically align with the wind direction, eliminating the need for a direction adjustment device. However, for downwind fans, because some of the air passes through the tower and then blows toward the turbine, the tower interferes with the airflow flowing through the blades, forming what is known as the tower shadow effect, which reduces performance. (The generally common fans are downwind fans, and Mingyang Wind Power's double-blade fans are downwind fans)
4. Other common classifications: According to the different mechanical connection methods of power transmission, they can be divided into "There are gearbox fans and direct drive fans without gearbox. According to the power adjustment method of the blade receiving the wind energy, it can be divisized into: "fixed pitch unit (stall type)" - the connection between the blade and the hub is fixed, and "variable pitch unit" - the blade can rotate around the center of the blade The shaft rotates so that the blade attack angle can be adjusted and changed within a certain range (usually 0 to 90 degrees). Depending on whether the turbine speed is constant or not, it can be divided into: "constant speed wind turbines" and "variable speed wind turbines". According to the classification of wind turbine generator types, they can be divided into two major categories: "asynchronous generator type" and "synchronous generator type". According to the output voltage of the wind turbine, it can generally be divided into: "high voltage wind turbine" - the output voltage of the wind turbine is 10~20kV, even 40kV, which can directly connect to the grid without the step-up transformer of the wind turbine. "Low voltage wind turbine" - output voltage is less than 1kV. Most models currently on the market are of this type.
