I freaking hate the pancake motors. We have 2 replacements for the step pulley motors, one in 3ph and a single phase variant. I am linking them here.
I will be on a service call this morning, so if you call, dont ask for me cause I wont be in the shop.
3 Phase
Single Phase
Hope this helps.

You guys are better than I thought. You can take a single phase motor and convert it to three phase with a few brackets?

Had to re-read both of these.
When I was faced with this problem I took a normal, flange mounting metric framed 1.5 HP motor and extended the shaft. It fitted inside the old pancake flange and worked perfectly with a VFD.

If that's a Brooke-Crompton, "normal" is a bit of a stretch!
Wasn't a Brook Crompton but it was 90 frame sized B5 flange mounting metric motor. Standard kit made around the world and I'm sure that Brook Crompton make them in that size too.
The trick was in paying enough attention to what the late John Stevenson posted about repairing motor shafts to extend the shaft to fit a Bridgy pulley and keep it all concentric!

Whats so bad about the pancake style of motors ?
I'd suggest a write-up on it, fotos and such. Or links to such if you have already done that.
Worth copying.
