Although the small wind turbine is an entry-level product in the field of wind power, it is still a very complete mechatronics system. What we see on the outside may be a rotating head, but its internal composition is very sophisticated and complicated. A small system with very high-tech content. Small wind turbines are one of the core components of this system. Other core components include chargers and digital inverters. Below we briefly introduce wind turbines.
A small wind turbine is composed of a nose, a rotating body, a tail, and blades. Each part is indispensable for coordinated operation. The blades are used to receive wind and drive the rotor to rotate to convert electricity. The role of the tail is to keep the blades always facing the incoming wind. Direction, so that the entire system can obtain greater wind energy. The swivel can be flexibly rotated according to the direction of the tail wing, which can be understood as turning wherever the tail wing points. The machine head is a key component of small wind turbines to realize the conversion of wind energy to electric energy. We have all learned in high school physics. The coil cutting magnetic field generates electric current. The rotor of the machine head is a permanent magnet, and the stator is the winding coil. The stator winding cuts magnetic lines of force. Electrical energy. This is the basic principle of wind turbines. In the design of the machine head, the highest speed that each rotating part can withstand should be taken into consideration. Therefore, the speed of the machine head should be limited to prevent the wind speed from being too high and the machine head rotating too fast to cause damage to the wind wheel or other components. When the wind speed is high or the battery is full, the brake mechanism should be activated, or the wind wheel should be turned sideways and wind direction to achieve the purpose of stopping.
Small wind turbines are divided into two categories from the basic structure: horizontal-axis wind turbines and vertical-axis wind turbines. Both have the same power generation principle but different directions of rotation axis and airflow. The two are in terms of power generation efficiency, production cost, use and maintenance. Each has its own advantages. For example, the horizontal axis has a larger sweeping area, slightly higher power generation efficiency, and the vertical axis does not need to yaw against the wind, so the structure is relatively simple, and the later maintenance cost is lower, etc., specifically about small wind power For more questions about the generator, you are welcome to call and communicate with us in detail.
