this is a 26 feet long cruiser but only intended for the canals, 4 miles per hour

thanks but I am non the wiser, this motor is intended to power a small cabin cruiser and so should never be in a position where it would stall and I can always guard against that happening, from what you have said so far, I feel comfortable with connecting this motor to a 150 volt DC supply, and...

the lower output is fine, but will it harm the motor with the field at same voltage, I don't really understand the relationship, ie what happens if I raise or lower the field voltage ? what happens to the current/ output etc

I need help with a Baldor dc motor, 15kw 240 volt armature and 150 volt field, I don't need the 15kw and so want to feed it with 150 volts to both field and armature, does anyone know the effect this will have on the motor, can I cause damage, what would be the approximate power output, I know...

thanks but I have thrown it in the bin

thanks for the information, your offer of a freebee is welcome but I live in the UK, rather a long way away but thank you

thank you, I have thrown it away, not worth bothering any more, as you say, there are plenty of motors out there, but mechanically coupling them to the Chinese blade assembly would be the bigger problem, I am not bothered what voltage just need something that will give me 100 watts at a...

I think that you have now answered my original question, ie, should I just chuck it away, so in the bin it goes, but thanks for all your very valuable help, think I'll now get back to my caring duties and maybe buy a wind turbine that actually works, but really, thank you, you have been very...

well spotted, I will change that, the original number of wired poles was 39, but because I wanted to use heavy duty winding, this was not possible to repeat, I didn't think that leaving out every other one would be a problem, bearing in mind that this was my first attempt at playing with...

please ask the most basic questions, I'm 80 and too old to get insulted, that said, I think that you have a valid question, yes it is enamelled copper wire, no, they are not yet soldered, just twisted together but I think that I scraped enough off for good connection, but thank you, I will...

I also have an Oscilloscope, I think that I will go and try again, although it's raining hard here, so may have to leave till tomorrow, but thanks for the prompt reply, regards

thank you to both of you, I will try to answer best as :- Baluncore diagram, I have simply wired these in 3 sets of 6 coils and star connected them, so three phase at present, can be disconnected and wired in which way way is suggested no rectifier meter works fine, any way, two meters the...

I should add, that I am not bothered about voltage, more important the some power is produced at whatever voltage

Hi, I am trying to rewind an existing Chinese alternator, it comprises of rotor with 12 magnets and 18 poles (stator), the original design produced virtually no power , aluminium windings have been removed and I have replaced with copper 20 gauge wire, 7 turns per pole, I spin it and nothing...
