DC motor, Run on AC

[T-Man]

Ok, this is the last time. I have my 8604 that has a DC motor. TOnight I got it to work on AC with one Radio Shack part. It goes forward and works. I just have to display the pictures but that puter is upstairs. It will take longer to post it than it did to get it to work.
I have another project to finish too.

First you but this part for under 3 bucks.
You have four connections. The two inners go to the frame ground and center pickup.
The red from motor goes to the + side and the black goes to the other side.
Easy.


...

The nice thing about these motors is that it has only two screws and you can replace it.
It ran like a champ.

...

You just installed a bridge rectifier.

OK, I suppose this will work on my 8625?

T-Man, was this directed at me, by chance?

Now I have to make a road trip to the nearest Radio Shack....2 hours away

I aim to please.

T-Man,

Just out of curiosity, any idea on how "pure" of a DC signal comes out of the bridge? I.e., is it true steady voltage, or does it have a pulse / step signal of high frequency?

Thanks!

For electronics Chips need filtered DC. To my knowledge it is not enough and needs capacitors. Look for my DC power supply.

[T-Man]

I have been thinking with a DTDP switch it can be made to work AC or DC.
DOn't know if you are interested in it.

TJ, what rectifier does is invert the "negative" part of the sine wave. so resulting DC is pulsed. which i guess not an issue for a motor.however to reverse direction there should be some sort of switch on the Loco, otherwise its always forwards.

Anton, does that mean the negative side's new sine wave is in step with the original sine wave? As in, do both curves peak at the same time and place? Or does one rise as the other falls? I can't think of any reason I'd need to know that, but you made me curious!
