Rotary encoders are used as sensors for angle,position,speed and acceleration. We can offer incremental encoders and absolute encoders.
According to the working principle, encoders can be divided into incremental and absolute types. Incremental encoder converts displacement into periodic electrical signal, and then converts this electrical signal into counting pulse, and the displacement is expressed by the number of pulses. Each position of the absolute encoder corresponds to a certain digital code, so its indication value is only related to the starting and ending positions of measurement, and has nothing to do with the...
At present, the encoder used in elevator is mainly incremental encoder, which is used together with frequency converter or other speed control system to provide speed and position information for speed control system or control system. Generally, frequency divider is added for pulse equivalent conversion. Encoder installation is mainly coaxial connection with traction motor to measure speed and feedback of motor. Now the door motor of frequency conversion door system is also equipped with...
The encoder corrects the reference position into the memory position of the counting device every time it passes the reference point. Before the reference point, the accuracy of the position cannot be guaranteed. For this reason, in industrial control, there are methods such as finding the reference point first, turning on the machine and changing it.
In practice, the faults caused by rotary encoder are not a few, and it is quite troublesome to check. Sometimes, although it has been checked, it is still not reassuring. Therefore, I would like to introduce a simple method to confirm the rotary coding fault. From the schematic diagram of the drive and regulation system, it can be clearly seen that it is because of the rotary coding that the microcomputer inverter motor is between. If there is a problem with the rotary encoder, the abnormal...
Flexible coupling for encoder The absolute encoder has strong structure and long service life. However, due to the frequent use of absolute value encoder and its mechanical movement, the absolute value encoder will be damaged in front of the adjustable resistance in the same machine; the adjustable resistance structure is simple, improper adjustment is easy to damage, and the life is short, but because of the low frequency of use, it does not show the bad place of its short service life.
An encoder is a device that compiles signals (such as bit streams) or data and converts them into signal forms that can be used for communication, transmission and storage.Encoder converts angular displacement or linear displacement into electrical signals, the former is called code wheel and the latter is called code scale.
The absolute encoder outputs multi-bit digital code (gray code or pure binary code), and the parallel output means that there are many high and low level outputs on the interface to represent digital 1 or 0. For the absolute encoder with low number of bits, the digital code is generally output directly in this form, which can directly enter the I/O interface of PLC or upper computer, with immediate output and simple connection.
Rotating photoelectric encoder is a mature technology for measuring angle and length. Nowadays, using absolute encoder with high precision and large range greatly improves the measurement accuracy and reliability, and is economical and practical. At present, it is still the most choice for measuring length.

High quality Optical encoders linear Incremental encoder is commonly used, and absolute encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the...
The sine and cosine encoder is equipped with permanent magnet synchronous traction machine to achieve more accurate leveling and comfort, and the comfort effect is the same as that of DC motor drive.
Incremental encoder usually has three signal outputs (there are six signals in difference): A,B and Z, which generally adopt TTL level, A pulse is in front, B pulse is behind, A and B pulses differ by 90 degrees, and a Z pulse is sent out every turn, which can be used as a reference mechanical zero position. Generally, A leads B or A before B-ultrasound is used for direction determination. The incremental encoder of our company is defined as the clockwise rotation of the encoder as forward...

Each position of the absolute encoder corresponds to a certain digital code, so its indication value is only related to the starting and ending positions of measurement, and has nothing to do with the intermediate process of measurement.
Manual sensor turbo encoder Generally, the signal obtained from the photoelectric detection device of the encoder is low in level and irregular in waveform, and cannot be directly used for control, signal processing and long-distance transmission, so it is necessary to amplify and shape the signal in the encoder. The processed output signal is generally similar to sine wave or rectangular wave. Because the rectangular wave output signal is easy to be digitally processed, it is widely used in...
Encoders can be divided into contact type and non-contact type according to the reading mode. According to the working principle, encoders can be divided into incremental and absolute types. Incremental encoder converts displacement into periodic electrical signal, and then converts this electrical signal into counting pulse, and the displacement is expressed by the number of pulses.
