An encoder is basically a sensing device that helps us by providing feedback. Encoders are responsible for converting motion to an electrical signal that can be read by several types of devices in a control system such as a PLC or a counter. These encoders are responsible for sending feedback signals that can be used in order to regulate speed, direction, or count. This acts as a control device and this information can be used to send a command for several distinguished functions. An encoder also works with a measuring wheel which tells us about the number of materials that have been fed to the device. Not just this, but encoders also tell actuators that what position a moveable mirror is in.
Encoders utilize several types of technologies that are used to create a signal which includes mechanical, magnetic, and resistive. This enables them to provide adequate feedback that would be based on the interruption of light.
Let’s have a look at several benefits that encoders provide us.
Positive Verification
Whenever a step motor will be pushed beyond its limits, it will reach its endpoint. This enables the motors to perform inadequately and therefore, it would not let things work out properly. An encoder motor provides positive feedback at the end of every process and indicates whether the step motor has reached its optimum position or end position or not. This controller also contracts these encoders and defines the actual position of the motor and also determines whether any difference was created. If the encoder does not match the actual motor position, the correct motion and process would be carried out. This positive verification is being used as the basic principle of the controller and this function is the most vital function before you start making calculations and corrections. It is ideal for every low-volume application and can be operated with manual processes.
Stall Detection
Stall detection detects whenever the motor stall occurs and eliminates the uncertainty of it reaching the end position. One more advanced function of this is stall detection which makes the controller compare and contrast and target the motor position on a regular basis instead of informing at the end of the process which makes everything more executable and makes every move more corrective. It avoids all sorts of disruptions in the machine and its functioning and enables human interventions. Not just this, but it also provides industrial solutions which have made our life easier.
Stall Prevention
Playing an important role in increasing the system’s functionality, an encoder ensures optimal and correct operation and enables it to move correctly. Stall prevention works dynamically and automatically and it keeps adjusting to prevent every type of stall which then enables the motor to keep working with constant torque in order to get in a perfect position without stalling. The speed is increased through stall prevention and all sorts of disruptions are avoided which makes the processes smoother and it successfully reaches the maximum and optimum point.
Increase In Motor Torque And Servo Control
Using the encoder feedback is used to servo control and increase the motor torque for a great and dynamic performance which assists in carrying out processes more keenly. With encoders, they are likely to perform 50% more adequately and get more responsible for dynamic performance. This servo-controlled system can operate at high acceleration rates which makes the system more efficient and faster than other machines. Not just this, but it also cools down the step motor and makes it run efficiently, quieter and faster, and assists it to work without sacrificing the speed of the motor. A higher resolution incremental encoder can definitely fulfill all these requisites.
Saves Time
Encoders are definitely the best thing that could save your time and can assist you in many ways. Setting the marker at any point will give you the best user preference and reduces the time. There are several applications where it also works as the tracer of starting and ending points. This saves a great deal of time and energy too while installation and especially when an existing encoder needs to be aligned on the same position again.
These are some of the most compelling benefits of encoders, showing and how they have been playing a great part in our life.
