Resolver is a kind of commonly used angle detection component, because of its simple structure, reliable operation, and its accuracy can meet the general detection requirements
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...
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...
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.
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...
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 control system. The signal...
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.
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.
The shield wire of encoder cable is not connected or falls off: this will lead to interference signal, make the waveform unstable, affect the accuracy of communication, it is necessary to ensure the reliable welding and grounding of shielding wire.
Good quality Resolver for business High speed end installation: it is installed at the shaft end (or gear connection) of the power motor. This method has the advantages of high resolution. Since there are 4096 cycles of multi turn encoder and the number of motor rotations within this range, the resolution can be improved by full range. The disadvantage is that there is gear clearance error when the moving object passes through the decelerated gear. It is generally used for unidirectional...
Loose installation of encoder: this kind of fault will affect the position control accuracy, cause the position deviation in stopping and moving to exceed the tolerance, and even cause the overload alarm of servo system as soon as the machine is started. Please pay special attention.
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.
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.
