dust collector motor replacement

[sunnybob]

My dust collector motor is worn out. The brushes were almost gone before they finally tripped the mcb. I replaced with locally sourced brushes, but its running slower and making a LOT of sparks so I dont expect it to last much longer.

Anybody know of a replacement motor for a sip 01923?
I've emailed sip but really really want to find another quickly.

One note of caution.
I replaced the brushes in an older SIP biscuit jointera few months ago. I went online found the model number, the exploded parts diagram and bought SIP replacements per the part numbers. When they arrived, they didn't fit. Not even close. SIP have had that machine in their lineup for a while, had obviously made mid life changes that meant parts from one generation didn't fit machines of another generation - but they just kept all the same part numbers.
That is a sin in any professional business, so be careful how much you trust them !

It won't help you find a compatible motor for your SIP canister, but for information the best quality vacuum motor / turbines and emerging as the world market leader these days are Domel. They make many variants for different clients and applications but replacement units are fairly affordable once you know what unit you need. A top quality replacement turbine costs about 20% the price of a premium extractor. Worth knowing if you have to choose a new one.

not inspiring, but tell me a company that has never made a mistake.
They have responded and say the motor will cost me £37, but havent told me if that is plus vat, or what the shipping is.
That could mount up to over half the price of a replacement machine. I shall have to explore a local motor rewind shop. Yes, they still have them here :lol: 8)

I think a rewind might cost a little more than the price of a new motor for one of those. I would suggest a rewind on an good old Brook Crompton motor, not so much on a cheapo extractor unit which are designed to wear out eventually.

This is only a small blower motor, almost no substance to it.
I have been told the price is inclusive, but UK postage is 6 quid, which takes it to about 43.
That is not too bad on a fan motor that has been worked quite well over 4 years.
I'll give the new brushes a day or so to settle in, if its still erratic then i shall have to bite the (£42) bullet.

If the brushes have worn the commutator the gaps between the copper segments may need to be recut. The motor shop would usually turn it on a lathe to even it up and then cut/rake out some material between the segments. The brushes will wear to conform. Whether it will be economical to do it is another story.

the copper segments look to be in good shape. I think one of the brushes collapsed and shorted the mcb. i havent stripped the entire motor, but having removed all the excess carbon with Q tips soaked in white spirit, I think I'm in with a fair chance.
