I recently purchased a brand new Leroy-Somer 0.25 kW 4 pole 3 phase motor with a 3 year manufacturer's warranty. It cost me £31.20 including Vat and delivery. …

.

That sounds remarkably good … May I ask from whence it came ?

I have just looked at their website and drawn a blank.

I purchased from a business seller on eBay. Good service, including next day delivery.

I had the same issue it turned out that it was not the lathe at all it was a fault with the wiring supplying power from the house to my workshop.

Still using the same single phase 1/2 hp motor on my home built 50 year old saw bench.

I suppose I must expect it to pack up one of these days.

And before you ask, this machine has done serious work, not just hobby work.cheeky

Old machines tend to be purely mechanicaL, and free of electronics.

Newer machines with elextronic speed control can be susceptible to voltage spikes in the power supply. A spike might be of extremely short duration, but of large amplitude. And will cause dame in the milliseconds that it lasts.

Hence the advice to feed through some form of surge protection.

My mini lathe is plugged into a surge protected dis board for that very reason

Surge protection is a lot cheaper than a replacement control board
