clay diggs Posted October 14, 2009 Report Posted October 14, 2009 If a 6 volt generator will "motor", does it necessarily mean it will charge when hooked up as a generator? Appreciate any information you might have. Thanks, Clay Quote
LuckyDevil Posted October 15, 2009 Report Posted October 15, 2009 Where did you read that? If you were reading it on an ad or something, it might just mean that it is not locked up. The bearing aren't locked up. Other than that not real sure. Quote
Plymouthy Adams Posted October 15, 2009 Report Posted October 15, 2009 if it motors..then yes it should charge...if it does not motor..then tear down and inspection is necessary to determine what may be wron..open field, bad brushes..leaded commutator etc etc.. Quote
clay diggs Posted October 15, 2009 Author Report Posted October 15, 2009 thanks for the information. Someone asked me the question and I didn't know the answer. Clay Quote
Jim Saraceno Posted October 15, 2009 Report Posted October 15, 2009 So I'm totally in the dark here. Just what does the term "a generator will motor"? Quote
Plymouthy Adams Posted October 15, 2009 Report Posted October 15, 2009 the generator is but a DC motor..if external driven (belt/pulley) will generate , if connected to a battery free of load it will motor..not fast mind you..but is a quick test of the components... get a small DC motor out of a slot car or toy..hook it up to a meter..spin the shaft... for the kid in all of us..hook a speaker in conjuction of a small motor..it will amplify it to sound like an engine..(maybe an asian made engine of small cubes but nonetheless you got noise that is relative to the speed of the motor) all I had as a kid growing up was broken toys so had to do something for fun...!

Wow! I'm an electrician and I don't think I ever heard of that. I knew that a DC generator and motor were basically the same but I never realized you could put power on a generator and it would run like a motor. You never stop learning, especially on this forum!

Merle Coggins Posted October 15, 2009 Report Posted October 15, 2009 I've used a similar example in a basic electricity training session I did for some of our technicians. When discussing the relationship between electric current and magnitism, which is the basis for electric motors and generators/alternators, I used an old heater fan motor and chucked up the shaft into my cordless drill. I connected the two wires to a light bulb. When I squeezed the trigger on the drill the light bulb would light up. Merle Quote
boxer_inv Posted October 15, 2009 Report Posted October 15, 2009 As it happens, I'm still battling with the electrical gremlins in my car after the rewiring. Took my generator out because it didn't seem to be putting a charge out, so got it tested yesterday at the auto-electrician. First test the old(er) guy there did was to see if it would 'motor' which it did - and I learnt from that:D. Then he tested using an external pulley and after some jigging around, it put out the charge it was supposed to be - wound up to 40 amps or more without any dramas. So, it seems my generator should be fine. That leaves my regulator as one of the last pieces of that little puzzle... Anyways, it was interesting to see how they tested it out, and I reaslised yesterday that essentially the generator was just a motor being driven, rather than driving. Quote
james curl Posted October 15, 2009 Report Posted October 15, 2009 (edited) I bought a new Corvair Spyder in 1963 and every time you reved it to red line on the tach it would throw the fan belt. After you stopped you had to put your foot on the generator pulley to stop the generator from running like a motor before you could reinstall the fan belt. I am having to type left handed by the hunt and peck method as I has my rotator cuff repaired, took three screws in the bone to hold the cables to the seperated tenon and the other torn but not detatched tenon. So I will not be doing many posts for the next six weeks. And using the mouse left handed is the pitts and so slow. Edited October 15, 2009 by james curl Quote
greg g Posted October 15, 2009 Report Posted October 15, 2009 Hey James, good luck with that, hope it heals well. Quote
Jim Saraceno Posted October 15, 2009 Report Posted October 15, 2009 took three screws in the bone to hold the cables to the seperated tenon and the other torn but not detatched tenon. Ouch! So... did they use 1/4-20 grade 8s? What was the torque values on those? And did they use red or blue thread lock on them? My lord, I didn't realize that rotator cuff surgery entailed all that. Rest up and I hope you're feeling better. Quote

I am looking at the same type surgery myself, hope you recover well. I am looking forward to no more cortisone shots...I wonder if they could put in a zerk for that? Quote
Niel Hoback Posted October 15, 2009 Report Posted October 15, 2009 Geez James, that sounds horrible. I hope you heal up QUICK and get the use of your hand back. I know what it is to be stuck with one hand, its been five weeks since the table saw incident, and now they tell me it will always be sensitive. Wanna buy a slightly used violin? Quote
Don Coatney Posted October 16, 2009 Report Posted October 16, 2009 Wow! I'm an electrician and I don't think I ever heard of that. I knew that a DC generator and motor were basically the same but I never realized you could put power on a generator and it would run like a motor.You never stop learning, especially on this forum! Jim; As an electrician I am sure you have heard of using a three phase motor as a third phase generator to make the third phase for home use. Use a single phase motor to spin a three phase motor that will act as a generator to create the third phase. Same principle as motoring a low voltage generator. I boght a new Corvair Spyder in 1963 and every time you reved it to red line on the tach it would throw the fan belt. After you stopped you had to put your foot on the generator pulley to stop the generator from running like a motor before you could reinstall the fan belt.

I hope to meet up with you in the next year or so. Quote

Neil; Just how slightly used is this violin? Hearing Humoresque (one of my favorites) on a violin always makes me cry:cool: Quote
Niel Hoback Posted October 16, 2009 Report Posted October 16, 2009 You would find nothing "humourous" if you heard Humoresque from me. I used that fiddle from 1950 to 1962. Considering how much I disliked it, its amazing that I still have it. There is no way to tell how old it is, or how many miles are on it, but it was a hard 12 years that I know of. I have a recording of my Dad playing that I can't listen to because it is so moving. We will speak no more of this. Quote
Frank Elder Posted October 16, 2009 Report Posted October 16, 2009 I miss my Pops too, as Bob would say, thanks for the memories. Quote

Use a single phase motor to spin a three phase motor that will act as a generator to create the third phase. Same principle as motoring a low voltage generator. Interesting.... Yes, now that you mention it, I heard that you could run a 3 phase motor on single phase by using a dummy motor to shift the third phase, but I'm not sure I ever heard exactly how to do it. Nor did I ever learn the theory behind it. Being linked to commercial and industrial work, we always worked with 3 phase so it was never an issue. After 35 years of electric work, I still run into things that just seem like magic! Quote
