A wind turbine is a turbine powered by wind energy. Wind turbines are like air intakes for jet engines. When air enters, it first encounters a set of fixed blades, called the stator, that direct air into a set of rotating blades called the rotor. The air pushes against the rotor and appears on the other side, where it travels more slowly than it would outside the turbine. Not only do we need to understand the definition of a wind turbine, but we also need to think about how to solve some of the problems that arise.

The encoder can convert the mechanical geometric displacement on the output shaft into pulse or digital quantity. This is the most widely used sensor at present. Since the photoelectric encoder is coaxial with the motor, when the motor rotates, the encoder (grating plate) rotates at the same speed as the motor, reflecting the current speed of the motor. It is mainly composed of four parts: light source, code disc, optical system and circuit. Then we will explain according to different kinds of encoders.

The wind turbine, borrowed from jet engine technology, overcomes a fundamental drawback of conventional wind turbines. A wind turbine's blades are surrounded by a shield that directs air through them and speeds them up, increasing the amount of electricity produced. A wind turbine is a turbine powered by wind energy. To make a wind turbine last, we need to learn how to maintain it. In this article, we describe the maintenance of wind turbines in chronological order.

Absolute rotary encoders have been more and more widely used in angle, length measurement and positioning control in various industrial systems because each position is absolutely unique, anti-interference, and has no power-off memory. There are many engraved lines on the absolute encoder optical disc, and each engraved line is arranged in sequence with 2 lines, 4 lines, 8 lines, 16 lines...
