An encoder motor also known as the motor encoder is a device generally an electromechanical device. This is responsible for providing electronic signals that are generally used to control position and speed.
Encoders are capable of turning out mechanical motion that is being received into an electrical signal or an electrical communication. These signals are further being used by any kind of control system to detect selective parameters of various applications or apps.
These then practically modify them according to the necessity if required to maintain the working and mechanics of the machine as desired.
Before we start talkiing about the testing of an encoder motor or motor encoder, it is very important to understand what it really is and about it. Knowing this will help us further understand the testing of an encoder motor.
An encoder motor or a motor encoder is a type of rotary encoder also referred to as a shaft encoder. It is a device that is generally electromechanical. It is responsible for converting the position of a shaft to an analog or digital outputting system.
This rotary encoder is further organized or mounted to a motor that is electronic. This helps in providing closed-loop signals by tracking the position and speed of a motor controlled shaft.
Testing an Encoder Motor
There are numerous videos all over the internet that show how to test an encoder motor. But most of these videos tend to complicate the very simple process. This is done in order to make it look more fancy and appealing.
Before starting to test an encoder motor, the user needs to understand what type of motor encoder he/she is using. There is a wide variety of encoder motor configurations available outside today. Few of them are magnetic or optical, absolute or incremental or shafted or hollow/hub shaft and also bearingless motor encoders.
All these varieties depend on numerous different factors. Mostly it depends upon the application that is responsible to provide the close-up loop or closed-loop function. It may also depend upon the type of motor that is being used. Sometimes it also depends upon the mounting configuration that is required.
However, steps for testing an encoder motor are reasonably simple. The steps are as follows:
- Firstly application of 5 volt DC current is required to the black and red wires.
- Next the voltage output needs to be checked for both the phases properly. It should be extremely close to 5 volts and a clean square looking wave should appear.
- If your signal is disturbed or distorted in any way possible, then you may have difficulty with the air gap present. It may also happen if your voltage is in any way low, even then you would be facing difficulty with the air gap. The air gap present is a major aspect of the functioning of your encoder motor. In case the air gap is incorrect it may cause huge problems in terms of functioning.
- The gap needed for the perfect functioning should be approximately 0.15 millimeters to 0.2 millimeters also depending on the model of motor encoder that you are using.
There can be numerous options when trying to choose a component for your motor encoder. But the first choice to be made is by determining the type of motor that is going to be chosen for your application.
Mostly the common types are used more frequently like the AC encoder motor for machines. These require automation control systems or Servo Motor encoders for applications and systems that need extreme accuracy, precision, and many more.
Moreover, any encoder motor that you will want to use may have very different types of systems. But the method of testing for all of these encoders is more or less the same. The steps of testing an encoder motor that is mentioned above, are the most accurate and extremely easy steps for you to easily test your encoder motor whenever and wherever you want to.
Unlike other videos, these steps are easy to understand and execute at the same time, and do not cause any confusion. Hence, with these steps, you will understand and will be able to test any encoder motor you want to very quickly.
