Any sources of info on circa 1880 electric motors?
I have been offered a C1880 electric motor, sounds like a big lump as owner says it is almost too heavy for him to pick up.
Hopefully going to look at it soon but would like to find a source of info on motors of this age before going to see it. |

Re: Any sources of info on C1880 electric motors ?
Is that C1880 a type number or as above an approximate date of manufacture?

Re: Any sources of info on C1880 electric motors ?
Hi Dennis, we have one like that in the discovery museum. It should be an easy repair/ restore. Probably best run on DC and will need a started.
Mail me if you need details for restoration Ed |

Re: Any sources of info on C1880 electric motors ?
I have only had a verbal description so far, c1880 about 18" high with oil bath bearings.
Should get to see it soon. Only got offered it as the conversation started out about vintage machinery, when I mentioned I was collecting and making the kit to be able to rewind and remagnetise magneto's the motor got mentioned. |

If it's like the one AC/HL linked to - what a nice thing! You'll either need an ancient lathe to run off it, or an atmospheric gas engine and drive it as a generator

This raises the perpetual conflict between conservation and restoration. Is it better to have an untouched but inoperable machine, complete with period dust, or to carefully restore it using materials available when it was made and thus conserve not just its appearance but also its technical characteristics? I suspect opinions vary according to technical knowledge and ability. PMM |

Re: Any sources of info on circa 1880 electric motors?
Have seen pic's now, turns out its a Crompton open frame dynamo 110V 35A missing field coils.
Anyone know what I should be paying for something like this ? |

Re: Any sources of info on circa 1880 electric motors?
I'd have said little more than scrap value, that's probably what happened to the field coils. There can't be much demand for stuff like this and transport would present a problem for anyone not living close by.

Re: Any sources of info on circa 1880 electric motors?
Hi Dennis, no idea on the price to pay, but it should be quite easy to replicate the field coils, they would typically take a max of about 3A at 110v.
Some research in old electrical mags will yield more data and with a slight shift of brushgear it will operate as a motor. Some research at a museum may reveal one in their stores that you could use to copy. Ed |

Maybe worth asking about this on an stationary engine forum. Edit: some info on Crompton on Grace's Guide with pictures of some that are in museums, including a motor generator set. https://www.gracesguide.co.uk/Crompton_and_Co David Last edited by factory; 8th Aug 2020 at 11:23 pm. |

Re: Any sources of info on circa 1880 electric motors?
I think you'd be hard pressed to find an enthusiast possessing a stationary engine dating from the 1880's and capable of driving this.
Asking about it on a stationary engine forum would alert others to its existence and might drive the price up. Options open to the seller would be to accept an offer from the OP, sell at auction, or sell on eBay as collect only or ship on a pallet. If I were the OP I'd make the seller a low offer and negotiate from there.

Re: Any sources of info on circa 1880 electric motors?
It sounds like the kind of thing which really belongs in a museum? Very early days of electrical generation and used by early adopters?

Re: Any sources of info on circa 1880 electric motors?
Well I have managed to buy it just need to go pick it up.
It's a higher output version of this one. |

Re: Any sources of info on circa 1880 electric motors?
That's lovely - I do hope you get it going / make some field coils and so on. In my view so long as you take a bunch of photos and make what you do reversible, so what? You kept it out of the bin, so you decide.

Spot on Mark. Spiders can find another home very easily, and a running example would be great.

Re: Any sources of info on circa 1880 electric motors?
Hi, the field coil looks intact on that unit and I see it has rocking arrangements for the brushgear.
Possibly come from a showmans traction engine? Ed |

Re: Any sources of info on circa 1880 electric motors?
Hi Ed,
The pic of the complete dynamo is one I found online in the Queensland Energy Exhibition Centre. Quote:
Might take a while to get to it as I have a rare 1930 motorcycle to get on the road first, which gives me time to do some research on the dynamo. |
