Air Craft use 400 Hz motors. They are interested in weight. Now that we are using Electric Steering, and Cooling fans, they may reduce their weight Slightly.

Just thinking.

Are the pics from this a thing of the past, or is it just me and my super paranoid browser settings?

I am amazed that I could have missed this thread, way back when it was first posted. So I'm glad someone referred to it in another thread today, and I've posted it on the front page for all to see.

I loved Frank's reaction...

There is one other project I know of where someone retrofitted an electromagnetic clutch to a truck to take control of an accessory... but it was to add on-demand regenerative braking to an EV conversion.

Well, now that the 2013 RAMs have electric power steering, I wonder how much they ask for the steering rack. Figure it can't be that hard to retrofit...
It still annoys me how one can't just go to the local auto parts store and buy a clutch, without the a/c compressor.

This must be another new thing as I worked at auto stupid back in 97 and 98 and they did sell them then. I will explore this a little.
Mabe just a sorry sales person, I also get them most of the time.
Look for an auto stupid in amongst or near dealerships, that is going to be a supplier yes your genuine GM ends up being guess who lots of times?

I finely got around to measuring how much power it takes to turn a P/S pump.
It looks like if you can keep the P/S turning at 850rpms it takes hardly any power to turn, around 150 to 200 watts.
But when you bring it up to a more normal cruse speed say about 2,000 rpms power draw goes up quite a bit. It took a little over 500 watts to keep it turning at that speed.

For my suburban 500w gets about half MPG.
