The motor is in the camera head.
It is mounted transversally in the very bottom of the head.
This camera is pin-registered and has a number of special features.
Although the aperture plate is instantly removable, it is fixed at
Academy width as that area which would otherwise be reserved for a
sound track is, instead, used for an Aaton-like timecode, possibly a
Russian equivalent of a KeyKode.
The plate could be expanded, vertically, for 'Scope, but there are
obvious issues with the viewfinder system.
The plate cannot be expanded, horizontally, for Super-35 or for Full/
Silent, as the LEDs for the Russian KeyKode system are in the way.
Now, as to the motor itself, it is of generous size, but it is belt
driven, using a timing belt through a set of right-angle guides which
are very tiny ball bearings.
The timing belt firstly drives the shutter/film movement gearbox and
secondly drives a gear which engages with a mating gear on each film
magazine for film take-up.
The motor's tachometer has a very high number of counts per
revolution, for very precise crystal control.
The crystal control unit, and, indeed, the camera control unit, is
contained in a separate box, and the camera is useless without this
control unit.
It is a quite innovative design, but as with most Soviet designs it
is not built to last, unlike a Mitchell or a Panavision. Or, an ARRI.
I believe the camera was designed for 25 fps, with 24 fps being an
alternate, but I doubt it was intended for more than 32 or 36 fps.
