Dynamic Braking Resistors for Motor Control Applications

Dynamic Braking Resistors for Motor Control Applications

Large DC and AC motor drives often provide terminals for installing a braking resistor. What are these resistors, and how do they slow down a machine? What hazards and cautions must be considered?


Introduction to Safety Relays

Introduction to Safety Relays

Redundancy and safety are often seen together in industrial safety systems. Safety relays monitor emergency devices to switch contacts based on status - but what makes them different from normal relays?

DC Motors - Why Are We Still Using Them?

DC Motors - Why Are We Still Using Them?

AC motors are common throughout industry - easily controlled by VFDs and without the maintenance that comes with DC brushes. So then, why are DC motors still used in certain applications?


How IIoT is Transforming Predictive Maintenance

How IIoT is Transforming Predictive Maintenance

The objective of predictive maintenance is to foresee potential machine failure with the help of machine learning algorithms provided with vast quantities of data.


Methods of Marking and Labeling for Wiring and Tubing

Methods of Marking and Labeling for Wiring and Tubing

Labels are such a small detail in the world of robotics and automation, they are often given very little attention. However, they play a vital role in proper system function - from installation to troubleshooting.
