In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...

For most people today, the lines between work and play, as well as the hours we allocate to each, have become blurred beyond recognition. Many find themselves burning the midnight oil at home juggling ...

The Allen-Bradley Branch motor control components have been revised by Rockwell Automation. According to the company, this move was made to update systems where components are used to turn on and off ...

Another intriguing issue is whether circuits in the remaining frontal agranular cortex—presumably involved in more ‘cognitive’ aspects of motor control—are organized in the form of primary motor ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!
