Training: Interpreting Motor Spec Sheets presentation wanted

[kmcclary]

As part of our preseason newbie member training, I wish to run a session on the basics of Motors, and interpreting Motor Spec Sheets.

Are there any Motor Industry Standard explanation app notes for understanding basic DC PM motor terminology, and interpreting motor Spec Sheet diagrams? Any Powerpoint presentations or PDF files on this which someone has made up for THEIR team? Even something as simple as a GIF of a combined motor curve (the "X and arch") with EVERYTHING labeled would help.

In essence, my goal is for them to not be freaked out or confused when they see a Motor Spec Sheet. I've seen a LOT of materials on gear ratios, SELECTING motors, et al, but most of them assume the students have SOME clue about motors already.

I wish to back up one step from all of the "choosing a motor" papers in the CDF Whitepaper area. I need class materials (for a one session class) to cover basic DC PM motor theory, motor spec sheet terminology (stall current, free speed, etc.), HOW industry diagrams motor specs, the basic equations that affect ANY motor, and how to pull the data you need FROM the spec sheet curves when you only have that instead of in tabular form.

IOW, ONLY theory, terminology and reading diagrams, and nothing about CHOOSING a motor for now.

Since this is NOT my area of expertise, I'd rather not try to make up one myself. Any links to materials would be appreciated. I'm sure others would like this too, so please post responses under this thread.

Thanks!
