In the wave of modern industrial automation and intelligent manufacturing,
incremental encoders, as a key measuring device, play a vital role. It is not
only widely used in fields such as automation control, industrial machinery,
robotics, manufacturing and automotive industries, but also has become an ideal
choice for real-time monitoring and control of motion processes with its high
precision, fast response and reliable performance.
Definition and working principle of incremental encoder
Incremental encoder (Incremental Encoder) is a device used to measure
physical movement, which provides accurate position feedback by converting
position or angle changes into electronic signals. Its working principle is
based on optical or magnetic principles and usually consists of a fixed part and
a rotating part. The fixed part contains a sensor (such as a photodiode or Hall
sensor), while the rotating part is connected to the object being measured. When
the rotating part rotates, the sensor senses the change in the photoelectric
signal or the change in the magnetic field and generates a pulse signal
accordingly. For each rotation, the incremental encoder generates several
pulses, and the number of pulses is directly related to the resolution of the
encoder.
Advantages of incremental encoders
1. High precision: Incremental encoders can achieve high-precision
measurements through fine line design and highly sensitive sensors. In addition,
through technical means such as frequency doubling circuits, the measurement
accuracy can be further improved to meet the needs of precision manufacturing
and control.
2. Fast response: Since the incremental encoder adopts non-contact
measurement, it has an extremely fast response speed and can provide real-time
feedback on the position, speed and angle changes of the object, providing
reliable data support for dynamic control systems.
3. Economical and practical: Compared with absolute encoders, incremental
encoders have a simpler structure, lower manufacturing cost, and are easy to
install and maintain. At the same time, its high resolution and reliability make
it have a wide range of application prospects in various industrial
environments.
4. Wide application: Incremental encoders are widely used in many fields such
as CNC machine tools, automated production lines, robots, elevators, textile
machinery, plastic machinery, etc. They not only provide accurate position
feedback for these devices, but also provide strong support for efficient
automated control.
