Type distinction and selection skills of hollow encoder

Hollow encoder is a relatively commonly used electronic component, so do you know its characteristics and the knowledge of encoder selection? Generally speaking, the shaft diameter of the hollow encoder is adapted to the extended shaft of the motor, and can pass Shrapnel to adjust the position flexibly. Secondly, the clamping method and shrapnel structure of the hollow encoder make it very convenient to adjust the position and absorb the vibration and impact of the load. and

　　 1. The advantages of hollow encoder:

　　(1) Multifunctionalization: In addition to positioning, it is also possible to remotely transmit the current position and convert the movement speed. It is particularly important for the use of inverters and stepping motors.

　　(2) Informationization: In addition to positioning, the control room can also know its specific location;

　　(3) Flexibility: Positioning can be flexibly adjusted in the control room. Convenience, safety and longevity of field installation: a hollow encoder with the size of a fist can measure intervals from a few μ to several hundreds of meters, n stations, and only need to deal with one hollow encoder (Changchun encoder) The safety device question can prevent many close switches and photoelectric switches from troublesome mechanical installations on the spot, and they are simply damaged by high temperature and water vapor. Because of the photoelectric code wheel, there is no mechanical loss, only the device orientation is accurate, and its service life is often very long.

　　 (4) Economicalization: For multiple control stations, only the cost of a hollow encoder is required, and the more important equipment, protection, and loss cost are reduced, and the service life is increased, and its economicalization is gradually highlighted.

　　 2. Function of hollow encoder:

　　(1) Support simple PLC or terminal multi-speed, support 7-segment; 7-segment acceleration/deceleration time and running time can be independently set.

　　(2) Adopt the open loop vector and V/F control mode of magnetic flux.

　　(3) Ultra-low noise, carrier frequency can be adjusted from 1KHz-15KHz.

　　(4) Two stages of acceleration and deceleration time and two stages of S curve acceleration and deceleration.

　　(5) Automatic torque boost and automatic slip compensation function.

　　 Three, the type of hollow encoder:

　　 (1) According to its internal reaction elements, there are photoelectric encoders and magnetic grid encoders.

　　 (2) Divided by its measurement method: there are linear encoders and rotary encoders.

　　(3) It is divided into output signals: incremental encoder and absolute encoder.

　　(4) It is divided into the form of mechanical mechanism: a bearing encoder and a bearingless encoder.

　　Four, hollow encoder purchase skills:

　　 (1) Whether the hollow encoder meets its own processing requirements and quality requirements. There are many types of hollow encoder systems, and a suitable system must be selected; since the drive unit is the key to the control of the hollow encoder, when selecting the drive unit, the appropriate drive unit should be selected according to the accuracy requirements of the workpiece to be processed.

(2) Space size: Due to the different use environments, the choice of the space size of the hollow encoder is also very important, because the encoder is connected to the internal components, and the selection of the appropriate size of the code is important for the installation of the machine and the arrangement of the equipment. Very good influence.

　　(3) The performance of the hollow encoder is mainly reflected in the processing of equipment data and its own material. Taking into account the different use environments, the encoder has more stringent requirements in terms of quality, wear resistance, and corrosion resistance. The data processing capability of the encoder should be considered based on the internal chip data processing capability of the device, and the higher the frequency, the better the processor.
