3 Benefits Of Using Dual Encoders For Robotics

As more and more manufacturing sectors rely heavily on robotics, the onus is on robot designers to accelerate innovation. A major challenge in terms of digital encoders in robotics is measuring the speed of the motor and the direction of rotation. 

Conventionally, two digital encoders, such as shaft encoders, are used for this purpose. One is placed on the back of the motor, and the other is placed on the back of the gearing. But since the motor rotation doesn’t equate to the rotation of the gearbox, it can cause inaccuracies. Here’s where dual encoders come in.

What Are Dual Encoders?

As the name suggests, dual encoders are a form of digital encoder that performs both measuring functions with a single encoder. That is, they measure both motor speed and direction of rotation. This is made possible by the design of the encoder, which features two rotors and one scanner.

Advantages Of Dual Encoders In Robotics

1. Simplifies Data Transfer

The dual encoders from Heidenhain make it easier to retain and transfer key data required for improving predictive maintenance and safety. For example, it helps determine the operating temperature of the motors at all times, a key part of improving the performance of the machine. 

2. Streamline Installation And Assembly

As the dual encoder is made of two rotors and a scanning unit, it greatly simplifies the installation of the encoder as it doesn’t require additional bearings or cables. Moreover, they are also easy to assemble, as they can be press-fitted onto hollow shafts with ease.

3. Easy To Check Installation And Performance

Lastly, dual encoders from Heidenhain come with diagnostic mounting software that can be used immediately to check if the rotary encoder is properly installed or not. Similarly, its performance can also be checked in real-time.

Walker Machinery, a proud distributor of Heidenhain digital encoders, will be more than happy to assist in this endeavour. We offer a wide range of incremental and absolute rotary encoders, as well as linear encoders that are designed for precision, accuracy, and the ability to function effectively in a compact space.
