Power Functions in detail, by Philo

Philo made at his website a great and very comprehensive description of new LEGO Power Funcitons elements.

You can find it here.

Article starts presenting all familly new elements and proceeds with a description of internal working details for the nerds.
Performance comparation with some older LEGO 9V motors is also included as well as new parts for LDraw and LeoCAD which can be deonloaded from the same page mentioned above.

This new system integrates an IR control interface, which is a new trend for some recent LEGO toys, like the RC trains and the new announced line of future LEGO trains which will replace actual 9V trains. New trains line to launch later in 2009, will integrate new Power Functions motors.

I think I had already seen an in-depth article about PF, perhaps at BrickJournal, but it's always nice to have a description at Philo's site, together with his excellent motor comparisons. The LDraw (and LeoCad too, even though I never used it) parts are a sweet extra, too.
If only the LDraw committee would finally end that "transitory phase" and continue making parts like these part of the official parts list, many difficulties with LDraw would be avoided!
Also, it would allow LSynth to include the new PF wire as a synthesiseable part, as well as the new crawler tracks... oh well, never look a gift horse in the mouth. ;-)

You are right! There were two similar articles at BrickJournal 8, which were written by Philippe Hurbain who is Philo anyway ;-)

The Power Functions system is great. It took a while to arrive but finally did it.
The good:
Two powerful new motors, the small being a nice size, come as a good addition to the somehow limited Technic repertory. Remote functions of course, provide a complete new way to interact with our creations.
The bad:
I wish they had kept the parts wire free, with the wire as an accessory like the classic Technic does. That would have allowed cleaner designs. Just take a look at the back of the "8275 Alternate Model" posted in the blog to see how messy the design can get. Of course that can be somehow avoided depending on the designer.
In conclusion the good out stands the bad greatly. I can't wait to see all the nice creations that will come from builders using the power functions.

Totally agree with you!
Who have thought that we wanted the wires attached to the motors???...

Maybe the have saved some space, as I believe LEGO never wanted to use a really compact connector for robustness. However it turned to be a very odd solution.

We will always end getting too much or too less wire...
Better to have separate cables of different sizes, like the former 9V ones.
