A DC motor that has a field winding? I need to find a way inside these
motors...
Older car starter motors had field windings - called series wound. Maximum
torque at stall. Will also run on AC.
Interesting.
I have some additional information. The black and white wires are
connected to brushes. The DC resistance between the two is about 2.7
ohms. The red and yellow wires have a DC resistance of 7.3 ohms. So I
guess they can be wires either series or parallel. What I don't
understand is if the red and yellow wires are for the field, then why
bring them out? Why not just connect them internally?
