Why are the wind direction of the wind turbine and the direction of the cabin different?

Why are the wind direction of the wind turbine and the direction of the cabin different?

This is a downwind unit, i.e. the blades are in the wind direction of the nacelle, which eliminates the influence of the nacelle and the turn on the airflow.

There are also units arranged in the direction of the wind. The blades are in the wind direction of the cabin, which avoids the risk of the blades hitting the tower.

Both arrangements have their own characteristics, and now the mainstream is the windward arrangement.

The speed sensor uses magnetoresistance as the sensing element and is a new type of speed sensor. The core component uses magnetoresistance as the sensing component, and then uses a new signal processing circuit to reduce noise and improve functions. Comparing with the output waveforms of other types of tooth speed sensors, the error of the measured speed is extremely small and the characteristicsThe linears are very coherent. The detected objects are magnetic materials or magnetically permeable materials, such as magnetic steel, iron and electricity. steel. When the magnetic or permeable material having protrusions (or depressions) on the measured object rotates while the measured object, the sensor outputs a pulse signal related to the rotation frequency to achieve the speed measurement goal or movement detection.

There is a Hall semiconductor chip in the magnetic field, and a constant current I flows through the chip from A to B. Under the action of the Lorentz force, the flow of electrons from I is deflected to one side as it passes through the Hall semiconductor, causing the film to generate a potential difference in the CD direction, called the Hall voltage.
