Author Topic: Rebuiding Neutronic platter moter? Stephen Frazza Expert Film Handler Posts: 161 From: Nutley, NJ, USA Registered: Mar 2004 posted 08-02-2004 10:56 PM                        I just finished rebuilding a stong/potts platter motor and i was wondering if there is anything you can do with a Neumade Neutronic motor. I checked the brushes and cleaned the commutator but it still gets stuck after being on for awhile. Any help would be great.  |  IP: Logged Kyle Watkins Expert Film Handler Posts: 185 From: Stuart, FL, USA Registered: Sep 2001 posted 08-02-2004 11:06 PM                     As of rebuilding them nto that i know ya. Graniger sell that type of motor way less then when we got them form nuemade. Dont have the part number though. the motor coems without brakcets and plug on the end, but all the screws fit right in. we had very good luck with them.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-03-2004 06:57 PM                     Best thing to do is replace the whole platter. It will eventually make you completely Neurotic!

Our tech essentially repeated Mark's comment above and tried to get us to switch over to Speco 270's. Neumade motors are pieces of shit, however, and even though the platter system is easy to teach novice projectionists, its far from superior in my experiences.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 01-21-2007 01:26 PM                 It has been 900 days since the last post.  |  IP: Logged Cory Isemann Jedi Master Film Handler Posts: 500 From: White Plains, MD, USA Registered: Jun 2004 posted 01-21-2007 01:26 PM                        The Grainger motor replacement is a Dayton 4Z140B motor. This motor is a perfect and fast solution. HOWEVER. Most of our replacements, within a year or less of installation, have developed an annoying squeak. Does anyone else have these type of motors with the same problem? Any solution? I'm about to go nuts with all this squeaking.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-21-2007 03:58 PM                     We rebuild alot of Neurotic motors. What happens is that from the motor running in a verticle position the carbon dust that is generated by normal wear of the brushes gets into the lower bearing. We use bearings with rubber seals so carbon dust can't get into them. The same is also very true of Christie AW-3 motors. I wonder if your Dayton Motors are now Chineese made like the rest of Dayton's Motors are. Not many people are buying them any longer as they have gotten to a point that they are really poor quality. Any of these motors are an easy 1/2 hour to rebuild..... we cut the commutator if worn and install new bearings.

I've never rebuilt any motor other than a Strong platter motor, but if it can be done I'd love to learn how.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-21-2007 05:46 PM                     You need a small lathe with a tiny round nosed cutting tool ground for cutting copper, the finest garnet paper you can find, a hummer to check the armature for shorts after you are done cleaning it up. Some time I could post pictures of the steps in rebuilding a motor if anyone here is interested. Mark  |  IP: Logged Adam Martin I'm not even gonna point out the irony.

Its pretty much at least a few motors a week through our shop. I just have to be around the shop and not on the road.

Sorry I was not there to get pics. Next time....

I am in the process of setting up anopther lathe with a collett closer. We wore out our other lathe and parts are non-existant... some Swiss made thing. Now that I have a better digital camera and more flexible lathe I will get to writing this up... hopefully this week. I may show a Christie motor being done but the basics are all the same. On Potts(and Strong) motors we just install a whole new armature for those armatures that are really worn bad. All the replacement parts for those motors are available thogh W.W. Grangers or directly from the motors manufacturer if you are able to buy parts in large quantities. Mark Mark  |  IP: Logged
