You forgot to carry the 1 There is 72 brushes on a SD35 just like the SD38's SD40's and SD45's (same for the dash 2 line) That is what is nice about the new Alternators on Dash 2 and newer. 8 Slip ring brushes replace 60 brushes that were on the Main Generator. The exception are the 80Mac's, they have 10. For some unknown reason to me, the Main Stator top slip rings have 4 brushes, but the bottom only has 2. The Companion slip rings only have 2 on top and 2 on the bottom. On the dash 2's, it's a mixed bag for the Aux Gen. You have to look and see what VR card is installed. If you have a VR 10, then 8 brushes for the Aux Gen, if you have a VR 11 through 14 you have a A/C Aux Gen. Same with the fuel pump and Turbo lube pump, they could be DC or AC. SD60's and above plus the rebuilds now have HVAC's so only the 38's and 40's have cab heaters and some of them have been upgraded with AC motors. EMD did take a step backwards with the 60's motors. You have 4 brushes per holder or 16 brushes per motor or 96 brushes per locomotive.All of the above is only for EMD locomotives, when you start talking GE locomotives you open a different can of worms. Dash 9's have 12 brushes on the slip rings and EVO's have 16.Both Dash 9's and DC EVO's have 3 brushes per holder and 4 holders per traction motor for a total of 12 brushes per motor. The Grid blowers have 4 brushes per blower with DC units having 2 grid blowers and AC units having 3 grid blowers. GE's have A/C fuel pumps and do not have turbo lube pumps.GE's have HVAC's. I'm probably forgetting something, but until all of the DC locomotives are retired, the carbon brush manufactures will be in business for some time to come And that class is just your first day, just kidding folks but at least I hope everyone has a better idea of what goes on under the hood of a locomotive.
David, Are you thinking just the motor or motor and wheel set? Could you make the motor to accept a user supplied wheel set?
I'd rather the motors not have a wheelset as well, be the ultimate cool if the support caps and gearcases came off !!Randy
I could make the motor accept wheel sets... kato I assume? or BLMA? Does NWSL have N scale wheels that look good?Got pics of what you are talking about? I don't understand.-David
Not N but this guy had a website for awhile...HO traction motors...https://www.youtube.com/channel/UCBksRIE-h4i_S510RjsyJSg
David,Can you 3D print these in metal? If so, what's the additional cost?
I could probably do it, but what is the purpose?-David
