Wind turbine encoder solution

While the world is looking for a new energy source, the wind power industry has gradually emerged. As a kind of clean and renewable energy, wind energy is receiving more and more attention from countries all over the world. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts, and the development prospects are very broad.

In order to meet the manufacturing and maintenance requirements of the wind power industry, okplazas.com specially designed dedicated encoders for generators, pitch, yaw and other systems, which can be used for wind speed detection, generator rotation speed and feedback position, angle, etc. information.

Customization, rapid response and continuous technological improvement have made us gain a good reputation in this industry, and we hope that we will become the first choice for encoder selection.

This article mainly introduces two schemes in the encoder of wind turbines for your reference.

-Optical encoder

Magnetoresistive encoder

1. Principle:

• When the magnetic impulse wheel rotates with the shaft of the machine, the MR sensor can detect the alternating changes of the N-S magnetic field.

• The sensor reacts to changes in its impedance.

• These changes are processed by the circuit to provide powerful digital pulses for accurate motor measurement.

• Magnetoresistive encoder is an ideal choice for harsh application environments, it can effectively resist a large number of pollutants in the factory, such as dust, soil or oil.

• Bearingless design, maintenance-free for life

2. Advantages and disadvantages

Advantages: bearingless design, non-contact, no mechanical wear for life

Disadvantages: higher requirements for the dimensional accuracy of the mounting surface

3. Advantages of sensor technology

1) Various magnets sticking to the pulse wheel will not affect the performance of the sensor

2) The influence of the radial distance between the magnetic ring and the sensor on the signal quality

The horizontal axis of the figure is the distance between the magnetic ring and the sensor, the unit is 0.001 inches

In fact, our sensor can provide relatively good signal quality within a distance of 0~0.08 inches (2mm), and is compatible with almost all drivers on the market (ST56 is rated at 1.5mm). If the signal quality is not considered, the maximum is 3mm. There is also a signal output

3) The influence of the axial misalignment of the magnetic ring and the sensor on the signal

The horizontal axis unit is 0.001 inches

The blue area is the standard alignment position

The green area represents "excellent" signal quality

Yellow means "slightly poor but usable"

Red is "unavailable"

A/B signal can provide excellent signal quality in the range of -0.375 inches (9.5mm) ~ +0.2 inches (5mm)

Z signal can provide excellent signal quality in the range of -0.125 inches (3.1mm) ~ +50 inches (1.27mm)
