What is an Encoder?

An encoder is a device that converts data or signals into a signal. In other words, an encoder is a device that converts linear displacement or angular movement into electric signals. The signal is transmitted directly to the counter and the counter, or controller transmits the signal in order to perform the desired effect.

What is the Role of the Encoder?


The function of the encoder is defined as the detection of the direction of the motor's rotation and the location of the rotation, as well as the speed at which it rotates. The encoder relays the signal it detects directly to the driver using an encoder cable. Then, it creates a closed-loop of feedback that will allow for better control.


For many, encoders are unfamiliar. So, we are using the elevator in our everyday routine to briefly consider the purpose of an encoder for all.


Imagine entering the elevator. We press the lever to the floor that we have chosen. The elevator gets the signal of the direction that the motor turns, and also determines whether the elevator is moving upwards or downwards. After an encoder "tells" the elevator control panel the number of rotations (number of turns) must be made and the elevator will swiftly and effortlessly reach the desired floor. The encoder is precise in controlling the motor that drives the door switch. The doors of the elevator open with precision.




Examples of Using Encoders in Applications:


Drug Delivery System


The drug delivery system has to dispense precise amounts of medication at a specific quantity. While developing the pump, feedback from encoders can confirm that the proper dosage of medicine has been given. The encoder ensures that the right dose was given to the patient. Encoders can be configured to have different resolutions, and designers can select the most appropriate quantity of lines. This ensures that accuracy is decreased to the lowest rate of flow.


Automatic Sun Blind


The sunshade's automatic system will give users the feeling of comfort in the environment and offer the ease of automatic adjustment of the curtain as well as the manual operation. Encoder feedback will provide details about the motor's speed, the direction of the motor, and the position that the sunshade is in when the power is turned off. This information will ensure that the user gets the correct position of shadow according to inputs by the console.




Electronic Assembly Equipment


Pick and place of SMT components equipment requires high throughput on automation of assembly lines. To get these outputs your motion controller has to be able to pinpoint the location accurately and repeatedly, while also recognizing the various weights and sizes of the PCB parts. The encoder resolution is exact movement, and allows for all axes to be synced to ensure that the components are placed correctly onto the PCB.


Manipulator ( Fixture)


The encoder plays an essential function in the fixture so that the speed and pressure of the fixture are managed to avoid damage to components. Each component could require different pressures and speeds for the function of grab. Feedback from encoders creates precise motion by determining the speed and the position of the motor needed by each part.


In short, encoders play a crucial role in the design of new products designed by engineers. The encoder is a source of information regarding the speed of the motor, its rotation direction, and location. The encoder's parameters are used to create the control system that controls your final item.
