A little while ago I had one of those immensely annoying – and unwinnable – arguments in an online forum with a guy I’d never met. You’d think the touchy topic was the wisdom of wearing a face mask (I ...

Blindly assuming the dynamic peak torques listed on servomotor data sheets for a design almost always results in over-sized, inappropriately expensive gearboxes. A motor’s acceleration peak torque is ...

The optimal size for a clutch or brake is determined by three things: Required torque, thermal horsepower per engagement, and average required thermal horsepower. Here, we'll discuss the first, ...

With or without a clutch pedal, all cars have three elements that make up their performance combination: the car's weight, horsepower, and gear ratios. When a torque converter is added in place of a ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Here is a simple method for estimating the actual load on an electric motor without special equipment. But first, a word of caution: Some applications (e.g., a large forced draft fan) require more ...

The high torque ripple poses a limitation on the application of switched reluctance motors (SRMs). In this paper, a current reshaping neural network (CRNN) is proposed to mitigate the torque ripple.

This appendix presents background information regarding bolting preload and safety factors used in bolting design. During assembly in the OEM shop, the BOP/LRMP stack is “built up” by placing one RAM ...
