DC motor

Found a website on the construction and workings of a DC motor.  What helped me understand it a little more was how a DC motor is physically constructed with the theory involved as well.  I know now that the stator magnets, which use N and S poles, are actually what keep the shaft rotating when current is applied through the coils.  The coils, with current applied, create an electromagnetic field that reacts with the magnetic field of the stator magnets.  What can sidetrack me is the fact that the polarity of the coil magnets change from N to S and back again as they rotate inside the stator magnets, but also seems to be the basic operation of a DC motor.

These boards are light...

After going through last year's spring quarter blogs during the electrical portion, I found something that reminded me that when I can't figure something out to slow down and let the problem air.  If I try and focus on the problem and not what my solution 'could' be, I seem to mentally block myself from any more figuring.

Here we have a light board that comes bare with wires to wire it all up.  Includes the entire lighting circuit for a Kenworth, judging by how the schematics are drawn up.  We had some trouble with getting the brake lights, stop lights, and turn signals to work properly.  After giving it a day to think about, we came back in the morning and studied the schematic and diagrams provided in the teaching manual.  We figured out that the blinkers and the brake lights both are wired in series with the blinker lever.  Once we found that out, the rest of it was in the bag. 

Here's a circuit we wired up with: a 9v battery, relay, wires, and a light bulb.  Crimped the wires for the relay ourselves, and can now be used as a tester relay.  Very handy.

K.I.S.S.  Keep It Simple Stupid

When we got together at the start of class and shared some really interesting stories about some of the experiences we had during our internships and jobs this past summer.  Some of the best knowledge I heard came from Raul and Ian, when they talked about their international experience in Denmark.  The whole concept of the fact that our profession is much more than just local, but global.  It is starting to make me look outside of whatcom county or fishing in Alaska for work.  

Here's a pic of us having a correct circuit board set up.  Load, control, and fuse are all necessary parts of a working circuit
