Encoder Motors and their Important Role in Home Appliances

Are you confused about what encoder motors are and what is their purpose in home devices? Well, worry no more because this is all we are here to tell you about.

What is Encoder Motor?

An encoder motor is basically an electro mechanical device that provides an electrical signal. It is used for speed or position control. It provides feedback to a control system by sensing a change in position. Therefore, depending on the type of encoder used, they can provide information about change in position, absolute position, and even the speed of the shaft. Moreover, close loop feedback or close loop control systems are the applications that utilize these motors or other sensors to control specific limits.

Types of Encoders

Some of the basic encoder motor types are as follows.

Optical encoder

It is the most wide spread type of encoder. It majorly composes of a light source, a rotating disc and a light detector.

Absolute encoder

Absolute encoders offer a single code for each position. Therefore, they make up two groups: single turn encoders and multi turn absolute encoders. Their size is small, which allows for a simpler combination.

Quadrature encoder

This is a type of rotating encoder that has the ability to show the position, direction and speed of motion. Moreover, among its many advantages, we can mention its ability to offer wide range of functions, simplicity and strength.

Linear encoder

It is a device or sensor that has a scale to determine its position. Sensors in the encoder read the scale and later convert its encoded position into a digital signal that can be translated by an electronic motion controller.

Incremental encoder

This is an optical encoder that finds out the position angle based on step by step calculations, where each position is completely unique.

Advantages of Encoder Motors

Devices that use encoders need to operate quickly with high accuracy. It is a device that is powers a motor. For example, industrial robots use encoders in factories a lot but they are not of use only there. They can also used in some home appliances.

Some of the advantages of encoder motors are:

Reduces Cost

The most obvious advantage of encoders is the reduction of replacement and listing costs. Instead of stocking encoders of different line counts, one programmable encoder would be more than enough.

Saves Time

Setting the marker pulse at any given point based on the user’s liking reduces setup time of an encoder. In some applications, an oscilloscope is used to monitor the channel. So, the encoder shaft can be carefully adjusted to trace the starting point.

Gains Flexibility

Another great benefit of using encoder motors is the wide range of features they offer. Programming offers the ability to match any changing needs of the end user.

Conclusion

Encoders are a powerful tool for electric motors. However, with so many options because of the sensing technology, absolute or relative position, and many options it can quickly become a challenge to find a good encoder for you. So, while choosing, always keep in mind different features of different encoders because every one of them is built differently for different uses!
