After studying the film in slow motion I believe i have worked out how it works, I even did a small experiment take a magnet and two steel blocks the same size as the magnet so it covers North and South
poles and place on both sides of the magnet, now place another bar across the top, the magnetic field is  diverted to the blocks and renders the magnet very weak on it face.

as you pull back the steel blocks the face becomes very strong and attracts the steel rotor face. the timing has to be done so when the steel rotor face just begins to  leave the magnet, the blocks neutralize
the magnet and let it continue its travel around.

Not a bad idea!
But maybe i did not understand correctly, but the steel shielding the magnets is the same quality as on the rotor? i do not think you will have the force (from the machine) to move it around the magnet...
maybe I am wrong...

I think you will have plenty when it is in motion if you notice there is a flywheel to give it the momentum it needs when it starts will be self sustaining there is a lever action from the cam follower as well and only has to move the blocks a few centimeters.

and any way a neodymium magnet even one inch square you could not stop the shaft from turning while attracting the steel plate on the shaft.

you can see where the block pivot shaft is mounted is on the periphery of the unit there are two identical setups  for both rotor faces ,
and there is a long cam follower arm and a week spring to over come as well as the attraction of the magnets to the steel blocks it should be  easy to overcome when you also have the flywheel moment to help.

all i can say is do the experiment with the magnet and see for yourself this could be the first magnet motor that can be made to work.

picture from film if you notice the steel blocks are a bit forward of the magnet when shielding could be important and also the blocks are substantially bigger than the magnet.

One thing else i have noticed he has a control lever with a knob i think what he is doing is lifting one set of blocks of the cam some how to chose what diction it will turn, has you can see in the film that it
first turns one way then turns the other as he engages one set of blocks or the other.

in other words one side is neutralized for one direction or both neutralized for off and the other for other direction, so far it all seems to fit what you see in the film in principle it is very simple but there are many variables timing gaps friction length of rotor steel plate etc.

I fully agree that there are lots of parameters to take into account.
But dont forget that this movie was filmed on film, at  a certain fixed frame rate. so that it turning in one direction, then in the other could very well be an optical illusion. You see that quite often when the motor speed reaches the frame rate it seems to stop, and then move in the other direction when the  speed gets faster than the frame rate of the shutter speed of the camera.

I am still convinced that the magnets are inside heavy steel tubing..
Look at the first pic you posted.. in reply #19 
the spring is attached to what looks like a tube... in this tube next to the spring there is a window cut into the tube. what you see inside imho could be a cylinder type magnet. It is shielded by the pipe, AND by another steel plate that has a bend in it so it would really stop attraction at a given point.

If the magnets were where you put them.. they would be too week as they would have to be quite small to fit. And at the time ( in the 50s and 60s) there were no neodym magnets. so we are talking ferrit magnets at the best.

But again.. i am just speculating. I do not know and might be completely wrong.

this is the video at the 14 sec mark first goes one way then reverses its very clear to see

https://www.youtube.com/watch?v=G6cycmBwLb8

I think the magnets where Alnico magnets as used in small motor ignition systems

and you can see him using the lever at first when it was changing direction

at first i thought it was in the tube my self but when you run the film in slow motion it is all clear to see i am not sure why the cutouts are in the tube but you can see it is hollow.

you can not see where the spring is connected but safe to say it is connected to the arm running down to the blocks to pull the blocks back of the magnet as when the arm is forward the spring is stretched  when the arm is back it is not  this would also allow the cam link arm to follow the cam from how it looks.

you can see the magnets in the center of the blocks for a start they are shiny with rounded edges as an Alnico magnet would look

I actually think neodymium magnets would present a problem with being to strong pulling on the blocks and causing to much drag, you would then need a stronger spring as well could be counter productive.

he has a 4 rotter plate model on his desk and the one running is an 8 plate model.

yes sir you are right for the direction change. thanx for pointing that out. the lever is very probable a distance lever to be able to stop and start the motor.
as for the magnets i am curious to see your firs tests..

I did a quick test with a strip of steel glued on a bearing wheel when the magnet is close to the strip it turns the wheel no problem right to the end of the strip sticking point where the interrupter would would work

looks good so far.

Another find this is where the spring attaches to the block arm but left out in this section

tried to analyze the working-cycle as precise as possible
please have a look at the attached paper

hope it helps.
