In this issue, we will introduce the characteristics and application scenarios of incremental encoders.

1、 Incremental encoder

The working principle of an incremental encoder is to convert displacement into periodic electrical signals, and then convert these periodic electrical signals into counting pulses. Therefore, in the control system, the magnitude of the displacement can be obtained by calculating the number of received pulses.

Due to the corresponding pulse output during the rotation of the incremental encoder shaft, the direction of rotation is determined and the number of pulses is increased or decreased through the direction judgment circuit and counter. Therefore, the incremental encoder can set the counting starting point arbitrarily, and during measurement, it can accumulate infinitely in multiple circles. Due to the fact that the Z-phase signal emits a pulse signal after each rotation, it can be used as a reference for mechanical zero position in practical use.

Sibo's incremental encoder belongs to magnetic encoders, which are achieved through the combination of magnetic steel, sensitive components, and signal processing circuits. When the magnetic steel rotates, the sensing element responds to changes in the direction of the magnetic field within the magnetic field, generating an electrical signal. After calculation, it sends out a pulse signal corresponding to the rotation angle of the magnetic field.

2、 The application of incremental encoders

Incremental encoders are generally used in scenarios where speed, direction of rotation, angle of movement, and relative distance are measured. Widely used in industrial automation, robotics, aerospace, medical equipment and other fields. Specific applications include:

1. Position control and motion control: Magnetic incremental encoders can be used to control the position and motion of industrial robots, automated production lines, and other equipment.

2. Measurement and detection: Magnetic incremental encoders can be used to measure parameters such as linear displacement, rotation angle, and speed, and are also used in fields such as automation detection and quality control.

3. Medical equipment: Magnetic incremental encoders can be used for position and motion control in medical equipment, such as CT, MRI, etc.

4. Scientific experiments: Magnetic incremental encoders can be used for motion control and parameter measurement in scientific experiments, such as material testing, nanomanufacturing, etc.

3、 Selection of incremental encoders
