    Hi

    I'm looking for introduction-level material on DC motors
    On the mainsite I managed to find this worksheet somehow:
    http://www.allaboutcircuits.com/worksheets/dcmcc.html

    I was wondering is there any article on the site that goes along with this worksheet? I assume the worksheet would be based on an article here somewhere, but i just cant seem to find it

    Please help!
    Thank you

    I'm not sure about the ebook chapter, but here's a really good video about DC motors

    You may also want to look into the consequences of field loss on a wound field shunt connected motor.

    Thanks for the tip!

    By the way I noticed in the video posted by strantor, which is from 1961 by the department of defense, and also in another video from 1965, when doing the "electric right hand rule" (ie using ur right hand plasing the thumb in the direction of the current in a conductor then your fingers show you the direction of the magnetic field this current produces) they show it opposite and say to use your left hand! This gives u a magnetic field in the OPPOSITE direction (!?)

    Perhaps back then they thought the magnetic field produced by current in a conductor went the other way?
