content: I have a Raytheon 2000B thermal camera. The camera powers up fine, but the germanium chopper motor does not spin. I metered the wiring inside the camera, and the motor is getting 4.96 volt on power up but the motor doesn’t spin. It’s a small Faulhaber motor, couldn’t find a model number. Just need to know what motor to order and any advise on how to migrate the old chopper disk to the new motor before reinstalling. Any help would be great!

content: Not got the Germanium version, but the OEM core with the film wheel is numbered 1516T012SCan have a look in my bins for spares if you are interested. Also the in-car cores used a common CD motor which might be better as it had more torque.I have plenty of thoseBill

content: Thanks Bill, I think your motor model is the correct one. I might go ahead a pickup a cd player motor will the same shaft diameter. They are much cheaper than the Faulhaber motors. Does the chopper wheel have to spin at a certain rpm?

It needs to be very well locked, hence the torque requirement and potential for instability.With Argus, when Raytheon introdcuced the 'digital' 205 series core we had to change the motors to the CD one as the Faulhaber was unstable on the new core electronics - related to how you could swing an Argus camera about.Bill

content: The CD motor type used in the driver vision cameras, and also Argus3, was type:Mabuchi RF300PA-11400Unlikely to be worth me offering to send you motors as I am in the UK, but do ask if you get stuck. I have lots of the Mabuchi but would need to work out if I had any of the Faulhaber to spare. I mainly have the 6V with gearhead variant that we used on the iris mechanism.Bill

content: The cd motor arrived, it’s too big to fit in the housing. The other problem I’m having is, how the heck do you separate the disk from the existing motor? The shaft isn’t threaded. I tried grabbing the collar with needle nose plyers and twisting it out. Didn’t work. I also, used a mini heat gun to heat up the shaft, thinking maybe it’s glued on, that didn’t work either. Any ideas how it’s attached, and can be removed? Or is this a part that has to be replaced as a whole? It’s fragile so I don’t want to break it. The front of the OEM motor housing is screwed to the plastic support from the backside, so the disk have to be backed off the shaft to even replace the motor.

content: I don't know about the exact assembly you have - especially with the Ge chopper wheel.All the drawings I have (200 series OEM core, with plastic chopper) have it glued on. Does not specify glue type, suspect some kind of epoxy though.On the Argus cameras where we bought a subset of parts to suit ourselves, we had a hub and screw.Bill
