Leroy Somer Motor's

[nigel1]

I have a Leroy Somer windlass, and I think they were fitted to many Beneteau's, plus the motors manufactured by Leroy Somer are also used in other makes of windlass.

For some time I have been trying to hunt down a set of carbon brushes (they come integral with a plastic cassette holder), but was having little luck.
I found one source in Italy, a company called Blue Traction, but as soon as I mentioned delivery to the UK, they stopped talking.

I eventually found a place in the UK called Alpha Electrics MBT - Alpha Electrics
and they are able to supply the parts.

The motor I have is a Leroy Somer MBT1141 S.

Hope this may be of help to any one else who is, or will be, trying to source these parts.

Hello Nigel ,

have you had any luck tracing the parts you need ?
My set of carbon brushes gave away also , but it's not the only issue I have with this type of windlass. The 12 volt DC motor applied in my case is the MBT84 L .
Please don't get me wrong , I'm not advertising for another board , but being a jeanneau owner I'm a boardmember on the jeanneau proboards forum . Infact I'm also a mod. , not that it matters.
But recently , I had to do some maintenance on my windlass ,....again .
This time , along with other issues , the brushes are worn down and finding a replacement is really tough .
Once I can lay my hands on the parts I need I will make a summary of all my issues with this terrible windlass and post it on the H&T (hints and tips ) section of the jeanneau board.
But as you stated , these dissasters were installed in many boats .
If we could make a joint effort in collecting and posting all the info we can get , meaning how to repair , where to buy parts etc . It is my believe this would be a great help for/to many.
It could be published on several boards , thus reaching as many boaters/owners as possible.

Just an idea.

The correct motor type is MBT82 L and not 84 L .
My mistake , sorry.

Yes, I got the parts, complete set of brushes in cassettes.
Once they were fitted, I removed the old brushes from their cassettes, and sent one of the brushes to this company
Carbon Brushes Suppliers manufacturers of carbon brushes
They made me a set of four spare brushes at about £14 each.
The original brushes from the motor have the wire leads "welded" to a steel plate in the cassette, but I found that the brushes can also be connected to the cassette if you have an eyelet crimped on to the wire, and attach to the plate with a self tapping screw (there is a pre-drilled hole in the plate).

This is also a good source of brushes if you can make something work...

Hey GordMay , I did stumble upon the links you posted some time ago.
I also emailed to Impexron ( Germany) last week , sofar they asked for more specs of the motor itself . Probably to determine the correct part ( brushes).

@ Nigel ,
Alpha Electrics doesn't seem to exist anymore , atleast the link in your initial post doesn't work .

Man , I think we're at the end of the line here , everything on that windlass breaks down. and no spare parts to find.

This is what I had to do/make a few weeks ago.


Alu drum on a SS spacer on top of the gipsy. Together with seawater that's what you get.






I hope this will work. Yet have to try it.


And this was last year's repair :


The chain run through to the anchor locker.
Alu , completely worn down . No extensive use you know , just sh*t material and bad design.


I still had some scraps & pieces and it took me almost a day to copy.
This has proven to work ,... up to now.

Now it's the motor ,brushes gone , commutator a bit worn out and requires a lathe-job , what's next.
I guess a new windlass will be in the pipeline , I' m just not looking forward to get a different design of whinch where the LS is now.

Impressive work bobs!

Thanks HMS ,

You can do wonders with a TIG and I'm not even a professional.
I wont be able to make the carbon brush module though.
I do have a lathe so the commutator will not be a prob.
Having alot of tools is great , but sometimes it prevents you from biting the bullet and buy complete new stuff.
I bought new sails this year , so I guess I'll pull another diy on the windlass for the time being .

Nigel ,

after checking my email box (sent messages) I did email them on november 8 , not received anything yet.
I've contacted so many companies the last week that I forgot about some of them.
This is becoming a nightmare and can not repair the existing moduke as it has suffered damage by using the wrong brushes.
I did change the worn original brushes , as you did , but I soldered them after cutting the original brushes out.
Maybe I've used the wrong type of carbon because alot of heat was generated and some brushe-holders melted away.

I hate this sometimes as well.... FAR too often I've gone and fabbed something up that while works perfectly... Fiscally makes little sense...

In the meantime I've received some quotes , and buckle guys , the cheapest was around 250 Euro for the carbon brush module.
That rules the option to replace this part completely out.

Nigel , do you remember how much you paid for the module ?
Could you give me the type of carbon brushes that you ordered as a spare ?
Maybe I can still repair mine .

Regards

[nigel1]

The module from the mBT1141 is completely different to the one for the 82. The carbon brushes are in individual cassettes.

I dont know the type of carbon brush, I sent an old one to Carbon Brushes Suppliers manufacturers of carbon brushes and they identified the material and made new brushes.
I had found out that the original motor had 22mm long brushes, so they made 4 brushes at 8 x 12 x 22mm.

[bobs]

Thanks Nigel , and you know what ? I've decided , today , I'm gonna buy a new a windlass.
Btw , the price above is VAT excluded.
VAT included , that means atleast 300 Euro's .
Which is 1/4 of the price for a new windlass ( even less) .
And all that for just the carbon brushes !!
I have set my mind on a Lofrance X2 project type , might go for the plus series , which is all S/S.

Regards.

PS :
Leroy Somer has disappointed me for the last time.
