Unfamiliar items made by Hoover - Page 2 - UK Vintage Radio Repair and Restoration Discussion Forum

The C5 motor was a permanent magnet brushed one designed specifically for it. As far as I can remember they where all made by Hoover in the UK.

Wikipedia says otherwise, but that is in no way proof of anything. I seem to remember having seen a picture confirming that Polymotor (my spelling was off) made at least one Sinclair motor. I will look for that picture. Meanwhile, if you spot a 12 digit article number starting with 8219, 4319 or something similar that would also confirm the Philips Italy link. On the other hand, presence of a Hoover article code (I have no idea what they look like) would confirm Hoover.

By the way, the same Wikipedia page, states that assembly of the vehicle was apparently done at the Hoover factory. Maybe that's the source of the Hoover connection in the stories.

Here's a bit of youtube I found, and it has tour round one. Yhe motor has a label on it "Polymotor Made in Italy". I'd only read of the Hoover motor before.

Well I never. The label on the whole thing says made by Hoover

EEVblog #501, I found it in the meantime as well. A Polymotor motor, with indeed a Philips 12NC which seems to read 9919 121 90189 (At least I got the 19 right, which means Italy) and a date of manufacture that seems to be 1985 week 8 (I think the C5 it is fitted in may have been manufactured in March 1985 given the 503 in its serial number). The specs 12V 29A 250W 3300rpm confirm that it isn't a washing machine motor, even if it looks a bit similar to various other PM motors made by Polymotor.

Of course finding a Polymotor still doesn't rule out they also used Hoover motors at some point in time.

After seeing some more pictures and the service manual, does anyone know who manufactured the circuit board assemblies? In the service manual they are refferred to as "a specialist sub-contractor" and the numbers on the boards don't seem to correspond to the Sinclair numbering system.

If this gets too off-topic, maybe a moderator could move the discussion to a more appropriate place such as the Modern Technology board?

Hoover made motor control boards for their other products so they have to be a likely source of the C5 boards. Sinclair had a lot of his other products assembled at Timex in Dundee. But he farmed everything out to whoever gave the lowest tender.

I made my grand daughter a wooden Land Rover, I powered it using a C5 motor which said it was made in Italy. I recently saw one for sale at Harrogate Model Engineering exhibition £65, I think I paid some thing like a fiver for mine, 18 years or so ago.Ted

I'm wondering... Did Hoover ever use Polymotor motors in their own products? Did they ever buy Philips products or subassemblies?
