Custom Rotary Encoder disk
A rotary encoder disk is a disc of rotary encoder, kind of device that measures rotational position, speed or direction of a shaft or motor. Disc is provided with certain textures or geometries through which rotational information can be sensed.
How Rotary Encoder Disks Work:
Rotary encoder disks are key components of rotary encoders, and their function involves the following steps:
Rotation and Marking Interaction:
- The encoder disk is also located on a rotating shaft.
- Due to the rotation of the shaft the disk also rotates and the data on it in the form of lines, holes, or magnetic zones affects a sensor.
Signal Detection:
- Optical Encoders: Light from an LED is projected onto the clear/(patterned) areas of the disk and a photodetector analyses the patterns.
Magnetic Encoders: The magnetic fields on the disk are sensed through a Hall sensor so as to produce signals.
Mechanical Encoders: Contacts located physically, so changes are felt when the disk rotates.
Signal Processing:
- Sensors create electric impulses or signals in dependence on the movement of disks.
- In incremental encoders, these signals define the number of steps taken in the movement.
- In absolute encoders, different disk patterns point to a particular spinning angle or position.
Output:
- The encoder communicates position, speed or direction data to a linked system including a motor controller or microcontroller.
Key Features of Rotary Encoder Disk
Pattern: The disk is typically divided into tracks or segments concentric with the track, each referring to distinct types of measurement such as absolute position or steps of positional increments.
Material: Optical encoders used glass and plastic disks while metal disks are often used in durability of industrial uses.
Functionality:
Incremental Encoder: The disk has parallel stripes or grooves, and these give the relative position changes.
Absolute Encoder: Each position in the disk is assigned a pattern so as to enhance position tracking.
