Does anyone recognize this motor brand?

Hi,
My Brompton had a nano conversation fitted in 2017 which has worked 100% reliably ‘till recently. The absence of drive power suggests the clutch might have broken - any advice received gratefully! First step will be to open it, which looks like it might be a threaded portion of the case, on the side with the torx capped screws?
I figure I need to id the brand to source the clutch - unless you, dear reader, can link me to one !

It's a Tongxin. IIRC, they either morphed into Outrrider, and I'm not sure whether they changed the weird metal rollers at the same time. If you have the metal rollers, you might as well chuck it and get a Q100 or Q85 (narrow forks), which are a lot better and don't cost much. Here's a thread on how to disassemble and repair:

I'd open it up first and see what's inside. If it has nylon gears, you might be able to get spares.

Looks like they might still be in business:
