Anyone done this? I was given a well used Dyson DC01 years ago by a friend, the original grey and yellow Dyson. Never ever tried it till recently and after a few minutes it smelt of burning. Someone tells me it must be the motor. Can't get new motors for it anymore but I found a place that sells refurbed motors for the DC01, fully tested for sparking, overheating and bearing noise.

I'll have to open it up to find out the motor as there's two types.

“One is called a YDK” motor and will have the code “YV940″ on the side
The alternative is slightly larger, and is made by an Italian company called Ametek. Predictably, this has “Ametek” on the side of it. "

So they have one of each type fortunately. Is it worth me doing this, ie, is this Dyson model worth saving and is it likely the motors will be ok for a year or two? £26 is a lot better than spending £200 on a new vacuum. Can't find any youtube vids on replacing the motor for the DC01, only for later models.

Check the carbon brushes first, they may show the same symptoms and it's a cheaper fix. Take pictures of the wiring as you go along.

I've got a DC07 with a dead motor but I've probably got enough working Dysons already :o

Have you opened it up and actually looked at the motor to see what condition it's in?

Haven't opened it yet, no. But what would I be looking for anyway? Would there be scorch marks?

Nightglow, that's a very good point too, maybe it's just carpet thread causing the problem, I'll check it out.

Where are the carbon brushes and what symptoms could I expect to see?

If you're looking for signs of the burning smell then that'd either be the windings are burnt out or brushes worn. The copper wire will appeared charred. This is unlikely if the motor still runs. If there's carbon dust everywhere then the brushes are most likely worn or the commutator is worn.

If you ever do get as far as getting to the motor then post a photo. I'll be able to tell if it's at fault. You'll also need to turn the blades and see if makes any scraping or rumble sounds.

That's great, I will definitely post a photo or two for you!
Assuming any carpet thread isn't clogging up the roller and overheating the motor as Nightglow mentioned.

The carbon brushes are little blocks of carbon on springs, they make contact with the commutator to supply power to the motor windings.
The commutator is the small cylindrical bit at the end of the motor with the copper stripes on it, each stripe is the end of one winding.


I found bits of spring in my filter so I'm pretty sure my brushings have exploded at least :)

Nice find. Thanks, I'll check that out as soon as I get a chance to open it up and I'll take photos of it. :)
 
Yeah, they are easy to open up. I washed everything with soapy water and it's literally like new again. It was solid with dog hair and what looked like brick dust.
