  1. I sold a full kit recently and the people that bought it are selling the motor on it's own. https://www.ebay.co.uk/itm/294207846612 You could buy it or I'll have another one for sale soon if you are interested? I didn't realise that they were worth so much money in running condition. They used my photos as well. So you can see the full picture and my kitchen table. Cheers
  2. Chris. I'm very interested if you want to sell it.
  3. Just one last thing. I've managed to track a 2perf converted one in London. I'm going to visit the guy who has it to pick up some spares. He suggest that we have a look at the conversion with a view to trying to emulate it. If he indeed has one and I can figure out what the modifications are I'll try to give it a go and be in touch once I've got one up and running. I'm still on the hunt for an original Cameflex one as from my understanding it could be switched from 2perf to 4 perf easily? I remember seeing some original Cameflex literature that mentioned it but can't remember where n
  4. Looks like it's in good condition for its age. What kind of price are they asking for? The main thing to check is if it is a CM3T which was the Cameflex original version or whether it has been converted. The was a guy in the UK converting them a while back. They are fairly easy to maintain and make sure that the mechanism turns easily. I use sewing machine oil to lubricate mine. Working motors are available on eBay quite regularly: https://www.ebay.fr/itm/Moteur-pour-camera-Cameflex-35-type-N40-n-118/313374343934?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26
  5. Looking for a working or non-work Techniscope CM3. No-working is preferable. Thanks
  6. Hello Boris, Sorry about the late reply. Seems that they are fully working GV-35 motors made by Eclair. Not sure if they'll fit a GV-16 as the GV-35 motor is on the other side of the camera. If you want a look two of them are currently on sale on eBay. I've posted videos of them running: https://www.youtube.com/watch?v=n_VktpBTz7Q https://www.youtube.com/watch?v=mfQuxe-jAoY
  7. Here's something crazy. I've been wracking my brains trying to solve the problem with the Perfectone motor. It turned out not to be transistors, capacitors or diodes. It was a piece of dirt underneath one of the contacts on the synch pulse generator. Just got it up and running Adam very happy. Apart from buying a bunch of components that I don't need now. So, now I've got the motor running I'd be interested to hear your thoughts about using the synch signal to provide reference to a speed controller. I found some photos a while back that showed a Perfectone motor controller that I assume
  8. GV-16 has a 27vdc motor. I have three working ones if you're still interested? I run them off 3 PP3 Batteries hooked up in series to make the 27v. It's a really cheap way of testing them.
  9. I set the multimeter to 2K resistance. Same thing happened today, plugged it in, switched it on, nothing happened. When I connected the multimeter to the two ends of the capacitor the motor started running. I didn't let it run for more than a second as I was using a V-lock battery that's rated just under 14vdc and the motor is rated 12vdc. The only thing I know about this motor is that they were for sale in the Cameflex Brochure back in 1971. So I reckon it's 50 years old. There's also a Motorola Transistor 2N 1557 5.36 but I can't see one in the diagram. I also got three old Camematic motors
  10. I would assume that "bridging it" is a more precise term. I forgot to unplug the motor and whilst I tried using a multimeter to see if it was working. I knew power was coming in but not reaching the brushes and was trying to wok my way back. I couldn't fin a schematic on the internet so I looked at the closest model to it which would have been a Perfectone NPR Motor. I gave it some thought and wondered if the circuit was a similar design. The switching seems the same and it contains so identical parts like the OC 30 transistor so I guessed that they may be similar. There's a 0.66uF capaci
  11. That's interesting. When I bypassed it the motor started running? What's it used for?
  12. Aapo, Sorry to bother you but I think you may be able to help me? I managed to get one the motors running that I go from eBay. I think I've identified it as a 12vdc Perfectone that runs at a constant speed. It has a synch pulse output which I think is similar to the some of the NPR motors. Not sure how fast it runs yet. However I got it running by accident when I by passed what I think is a capacitor. It's marked up as .22/300 B32 226. I think it's a Siemens. Could you suggest a replacement as I have no idea where to begin or how to identify what spec it is? Cheers Marek
  13. PID. Thanks for that I'll be going down that route in parallel to the BLDC motor controller and Arduino as it's much smaller than the PID H bridge I've come across. However it's a really cheap price which is what I was after initially.
  14. Don't think they're the ones you were looking at. Two of them are 24V DC and one of those is a 16fps Rank Shunt Motor. There's one for sale on eBay at the moment in New Zealand. The other is a 27V AC Kinotechnique one. No idea where to get at 27V ac power source. It may be that it's use for single frame operation. The Camematic motors are fairly unique. One even has a speedometer built into it, same as the one on a CM3. Looking to see if they all work and if they can also be modified for Cameflex use. If not, they'll be back on eBay in a couple of days. I'll see if I can get ll the other
  15. I'm still interested but looking for the cheapest solution possible. Currently working with a $10 BLDC with Hall, a $4 motor controller and a small Arduino. I can run the motor and control it from the Arduino. I just need to spend a bit more time on that as I'm currently preparing a couple of Cameflex CM3's to sell on eBay in about a month. Once I've done that I'll be back on the motors. All this is predominantly to shoot my own stuff. I'm also going to mill up some aluminium bobbins for my 100' mags. If there's any interest I might make a few for sale. I recently got a 100' mag with an origin
