a thing that joins together two parts of sth, two vehicles or two pieces of equipment.
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 main performance requirements of encoder are: high precision, high sensitivity, reliable work, good stability, strong anti-interference ability, good dynamic characteristics, simple structure and low cost. The main items to be checked include: appearance; starting moment of main shaft; allowable speed; allowable axle load (axial and radial); inertia moment; vibration resistance; shock resistance; high temperature resistance; anti-interference ability; power voltage adaptability; current...
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.
Encoder manufacturers use the principle of clock gear machinery. When the central encoder rotates, another set of encoder (or multiple sets of gears, multiple sets of encoder) is driven by gears, and the number of turns is added on the basis of single-turn encoding to expand the measuring range of the encoder. Such an absolute encoder is called a multi-turn absolute encoder, which is also encoded by mechanical position, and the encoding of each position is unique and not repeated, without...
Dual concentric rotary encoder 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...
Absolute pulse encoder: APC incremental pulse encoder: SPC both are generally used in speed control or position control system detection components. Rotary encoder is used to measure the speed of the device. It can be divided into single output and double output. The main technical parameters are the number of pulses per revolution (dozens to thousands), and power supply voltage. The single output means that the output of rotary encoder is a group of pulses, while the two-way output rotary...
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...

It can convert the displacement into periodic electrical signal, and then convert the electrical signal into counting pulse, rotate the incremental encoder to output pulse when rotating, and know its position through counting equipment.
After mastering the output format of serial data, the verification mode of data, the pulse period, the duty cycle of pulse and the corresponding data relationship, the application program is written according to the requirements of coded pulse output, so that the MCU can realize the function of encoder.
The Coupling of shaft encoders It is a kind of rotary sensor that converts rotary displacement into a series of digital pulse signals. These pulses can be used to control angular displacement. If the encoder is combined with gear bar or screw, it can also be used to measure linear displacement.
When the encoder is installed, it can not only monitor the out of step condition when the motor is running, but also monitor the motor load response signal supplied by the encoder, which makes it possible to supply only the required current.
Good quality Miniature absolute encoder Photoelectric encoder (65) encoder (1042) sensor (12527) photoelectric encoder is a kind of sensor that converts mechanical geometric displacement on output shaft into pulse or digital quantity through photoelectric conversion. This is currently the most widely used.
Encoder (525) orthogonal encoder (also known as dual channel incremental encoder) is used to convert linear shift into pulse signal. By monitoring the number of pulses and the relative phase of the two signals, the user can track the rotation position and direction.
