DC can motor to AC

The bridge rectifier should have a + and - marking on it. These get connected to the motor wires. The other 2 terminals marked ~ on the rectifier get connected to track power (center rail pickup and chassis/wheels ground.) Reverse the motor wires to get the motor to run in the opposite direction.

Thanks for he help but I must not be following you. #1 I hooked the bridge rectifier up as directed and got nothing. #2 I was also told that I needed a capacitor for it to work. I have one but I have no idea how or where it should go. Any and all help is greatly appreciated in getting my train to run. Thanks

You shouldn't need the capacitor for it to work.

Maybe the motor is bad.

Try testing with just a 9 volt battery.

Like Flash has mentioned you don't need a capacitor! 

I have two Williams F-7's with just a 50 volt 6 amp bridge rectifier in each one, each F-7 is powered with two can motors. You wire the bridge rectifier with ~ signs to the track power, and + and - signs to the motor wires. If it runs the wrong way reverse your + and - wires to the motor, reversing the input wires won't do anything for direction.

Thanks to all of you who took the time to help me out. All great info that I'm sure will work when I get a new can motor!! Apparently the one I have is dead! It was running a bit rough last week and finally gave up, I thought it was dirty or the wiring was to blame, not thinking that the motor could be bad. Now I need to find a replacement motor, any suggestions ?  Remember, I need a can motor with a long enough shaft so I can press on a worm gear, that inturn drives the gearing and chain that powers both axles in this costom David O King work engine. Thanks for your help and support.

I have a few David O. King items in my collection. Would you like to post a photo of the one you have?

Sure thing I will try to post one soon.

This is my David O King work car/engine. it needs a new can motor to fit in the cab, it was running up to just lat week. I truly enjoy buying and running odd/custom pieces. In fact I am starting to do the same, except I am making standard gauge pieces, easier to see and handle as I get older. Haha

 By the way there is an old yellowed piece of paper on the bottom with David's name on it. I got it at an auction a few years ago.

I hope the photos were of some interest to you. 

Do you know where this can motor came out of? I ask because there are many can motors out there and the worm gear will be different depending who made it and for what model.

Yes and no. The "can" motor came out of a custom made work car built by David O King out of Brooklyn NY. I do believe I will have to carry the thing with me to all the meets I attend to see if I can find a replacement. Thanks for your reply, I am very new to this Forum thing and have found it quite helpful and interesting.

NWSL - www.nwsl.com sells can motors of many different sizes.  If you do not see what you need, give them a call as they provide good service and assistance.

Thank you for the information. I will look into it and hopefully respond with good results.
