Has anyone had any experience in salvaging old DC motors from scrap cars in the uk?
I cant seem to find anything useful on google

I live in Kent, Does anyone know if there is any salvage yards around here?


thanks

 

If you go to yell.com, enter 'scrap yards' and 'kent' you get 51 hits!.

Ok thanks nigel.

 

I hope you're not thinking about using a starter motor in a robot or something as it isn't suitable because it isn't rated for continious use.

No, but i am thinking of using windscreen wiper motors.

 

You've also got electric window motors. They're slow, but pretty powerful!

window motors are pretty powerful, but are notoriously badly made. Very similar to cranking motors, in that they are enormous power pigs, shoddy construction, etc since they have a very low duty cycle.

seat motors, and many of the small " only runs for a few seconds" motors found in cars & trucks are just as bad.

wiper motors are a better bet.

 

A wiper motor is good and so is a blower motor if you want a motor that's rated for continious operation.

Do you mean the heating system blower?

 

Yes he does.

But wiper motors are really pretty good!.

Did you ever watch Robot Wars?, one of the best robpots was called Cassius, and it was really the first to be self righting, and was famous for actually flipping up in the air and landing back on it's wheels - I think it won at least two wars?.

Anyway, the guy (Rex something? - Garrad?) who built it actually makes special effects, for movies and anyone who wants them (moving displays in museums etc.)

He's been using Bosch wiper motors from scrap cars (probably the most common kind?) for years and years, usually running them at 24V so they run faster, and he claims NEVER to have had one fail!.

Robot wars used to be good for the first few series but then it went downhill; eventually it was relegated to channel 5.

It's a shame, they should've kept changing the rules to keep the designs changing from year to year.
