Hi Mark,

Amadeal, Chester, Warco, Machine Mart and (I think) Axminster sell mini-lathes with brushed motors but check the mounting arrangements and power rating.

Thanks for the information Neil I will have a look at what they have to offer

Are you sure you need a replacement motor?

For example, are the brushes worn and are you sure the supply is getting to the motor OK?

You may save a lot of money if it is not the motor. I am sure help is at hand on this forum to carry out some checks if you need it. However, if you do need a replacement Neil's advice is good.

Regards

John

John, I have a new set of brushes as yet not fitted the original are about 20-25% shorter than the new ones my initial thoughts was worn brushes and it still may be but I like to be prepared for the worst

From the above list, Chester is the only one who might have them – for their Conquest Lathe Super. I know that their PR says 400w, etc.etc., but it is the 350w brushed motor. Their Conquest Lathe Super is a SIEG C3 (not a SIEG Super C3).

ARCs stock of this motor spare expected back by end of this month.

Ketan at ARC.

Thanks for the information Keten, initially I had noticed that the chuck had a notchy feeling which was becoming worse until the motor started what I would describe in mechanical terms as misfiring I don’t know the electrical term, my first thought were knackered bearings and brushes these were replaced least ways I bought some several months ago but haven’t had the time to look at the lathe, I have now striped and rebuilt the lathe and it would appear that the brushes use about 20-25% before they lose contact and the motor starts misfiring once the drive belt was removed I tested the chuck bearings and all seemed fine the notchy feeling was coming from the motor not the chuck so as I had the bearings (ArcEuro 7206B-2RS Spindle Angular Contact Bearings) I replaced them as well as the brushes also a liberal application of nice grease as opposed to the sticky mess Sieg use reassembled everything and it works a treat once again and the notchy feeling has gone from the motor on the plus side the motor has gone from spinning at 3000rpm to 3400rpm, the increased performance I can only put down to better quality bearings and better grease, so now I can start on my 1/6 scale Panther tank :O)

I have an X2 which has a similar motor. With the power off there is a very definite 'cogging' feel to the motor – not eth bearings, it's the interaction between bearings and magnets.

It's the same motor (provided it is specifically a SIEG X2 mill), with a slightly different mounting and a paint job.
