Based on the 2020 National Electrical Code. Part 1 of this two-part series taught you how to calculate branch-circuit loads. Now let's review how to perform feeder and service load calculations.

To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...

The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...

Ok, I lied. This is more of a "do my math" request than a question. I'm working on a project that requires lifting a 10 lb load vertically using a lead screw (threaded shaft) and then lowering it ...

The new Allen-Bradley LDAT-SeriesTM Integrated Linear Thruster from Rockwell Automation is the first commercially available moving magnet iron core linear motor actuator with a built-in linear guide ...
