Video - Encoders Help Detect the speed and direction of motion

Transcript:  

Today we will discuss encoders. What are They and What are They Used For?

Industrial encoders are a commonplace technology in the industrial sector. Encoders are used in a variety of ways, but always to detect the speed and direction of motion in one form or another.

John Brooks supplies this critical product that enables all kinds of different motion applications. To fully understand an encoders impact, it’s important to first understand the different types supplied by John Brooks.

To fully understand encoders, we need to understand that all encoders provide some method of feedback detection a full rotation of the encoder. It’s the method of detection that varies between different types of encoders.

Optical encoders are very accurate encoders, although they are highly susceptible to contamination from dust, vibration and other environmental conditions in an industrial environment. They detect changes in angular position to communicate motion control information.

Magnetic encoders are used in rugged industrial environments because they are less vulnerable to contamination than optical encoders. In this type of encoder, sensors detect changes in the magnetic field of a rotating disc and translate this information into a digital format.

Encoders also come in linear or rotary models, depending on the direction of motion they detect, and can be categorized into light duty, medium duty and heavy-duty models based on how rugged an environment they can withstand. Industrial encoders are either incremental or absolute, depending on how they use location information.

John Brooks offers encoders that can be used in linear measurement, timing, tensioning, backstop gauging, conveying, filling and many more. However, by far the most common application is providing feedback in motion control of electric motors.

In the industrial sector that John Brooks specialises in, nearly half of all electricity goes to power electric motors. Some of these motors have encoders of some sort. John Brooks offers encoders that come in many shapes and sizes, however they always detect the speed and direction of motion in one way or another.
