This is a fantastic explanation for which I am extremely grateful.
I have a couple of further questions that this has raised:
1. So it is looking like the lack of a field current has meant that there is no longer any back EMF. If the current was to raise that rapidly and to that sort of an...
Good morning all,
My bias is towards control systems so when I was met with a DC motor fault yesterday I have had to admit where the shortcomings in my knowledge are and clearly it is DC motors.
I have the circuit below (simplified for clarity):
The incident that occurred (as far as I can...
I agree that 13849 isn't particularly prescriptive. Just wanted to make sure that there wasn't something obvious that I had missed!
I've done the maths both ways and the performance level comes out the same regardless so I'll give them that this time!
Thanks for the assistance.

The intent of seperating the circuits is not to stop the different parts of the machine independantly as all parts of the machine would need to be stopped in the same way (according to the category of stop). I believe it is purely to make managing the control circuit calculations simpler for the...
Good afternoon all!
I am wondering if you can help settle a dispute I am having with one of my colleagues. We work in amusement devices and specifically reviewing designs for electrical/control systems.
I am currently doing a design review for a client where they have split up some of their...
