thanks

You'll find lots of expertise on this sort of thing at the NBTV Forum.

... and being in Leicester, you might want to consider popping across to Loughborough University on 2nd April for the NBTVA's annual convention.

You may find you can still buy a synchronous motor from e-bay, but it may not be the correct size. To replicat you would need to get the correct laminations. This is probably extreamly difficult as most motor lams are now in metric sizes.
A possibility, depending on motor size and speed requires may be to us a modern servo motor, BLDC type or stepper motor.

The Nipkow disc spins at 12.5 revs per second or 750 RPM. The motor does look fairly simple so I shall have a go at replicating it first.
thanks

The NBTV Association has a 20" professionally-cut 30-hole disc available to order, subject to a minimum quantity of two. I strongly recommend the club to anyone interested in the pioneering days, and the annual convention is an eye-opener for anyone who believes the old chestnut that mechanical television is 'crude', and of 'no entertainment value'.
