Motor/Generator combination

[Westland]

I am starting this thread because at one time there was an individual who actually manufactured (on a very small scale) motors that also worked as generators. You would pull a rope like a lawnmower starter to start the motor, and then it would generate power plus the electricity needed to keep the electric motor going. I have some thoughts on this as well as some other things I have run across that I want to make sure I share with others.

Here is a link to a video of a motor that also acts as a generator. It is definitely NOT overunity, but hey, we have to start somewhere.

Thanks westland , I think what i saw on your video was facinating. You have made reference to the motor generator in other posts that was sold many years ago. Do you recall what it was called? We might be able to hunt one down
Kind Regards

John Bedini talks about it in the "Energy From the Vaccuum" series part 14. It was called the Lockridge device. It was (according to John) sold to people to use as a power supply when they went camping. It only put out about 300 watts, and was built from an alternator. It used primitive, home made capacitors to store the charge it produced. John shows a replication of one in the video, but it doesn't work and is not really even put together. The brushes it used were specially modified and when they wore out, people replaced them with standard brushes and then the devices no longer worked.

I am interested because of what happened to me. I had a small 12 volt electric motor that also used brushes. I was using the circuit I demonstrated in the video with the motor in place of the coil. So not only did I have the mechanical energy of the motor, but IT PRODUCED A CHARGE. I had it hooked up to all kinds of stuff! Then suddenly it stopped working. And has not worked since. Nor has any other motor I have tried. But that's why I feel like this is "a" correct direction to look.

Any regular DC motor will work as a generator, its called a Dynamo.

Modern motors are "brushless" and have transistors to actuate the field coil.  They do not generate electricity, and you can burn out the transistors trying.  But if you can find some surplus old school DC Motors with brushes, then you can generate electricity wit them...

Scroll down to Dynamo...

I understand that. Put electricity into the two wires, it turns the shaft. Turn the shaft and the two wires produce electricity. The goal is to build a motor that runs on electricity it produces itself. Or a generator that produces enough electricity to run itself PLUS other devices. And if you are going to say it can't be done, it already HAS been done, and we have lost that technology. It was called the Lockridge device. Not just one was made. Many of them were made and sold here in the U.S. I am talking about trying to rediscover that technology
