As we've discussed in the last two Code Calculations articles, when calculating the total load on your system, you must first identify specific types of loads. Then, you can calculate each load. For ...

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.

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 ...

The electrical panel, also known as the service panel, is the control center for all the electrical circuitry in a residence. Today’s panels are bigger than earlier versions. They have to be, because ...

Science Progress (1933-), Vol. 103, No. 1 (2020), pp. 1-36 (36 pages) This article proposes a conceptual model of a new type permanent magnet 3-degree-offreedom motor. Its structure consists of an ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

My Feb. 7 column focused on ice flake machine troubleshooting. I will have more to say on that specific topic in my April 4 column. For this column, I want to take a look at amperage as it relates to ...

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 ...
