I was delighted to find your interesting videos on the Emerson 45041 DC. I have the same type (45041) only mine differs with a bell housing for a large globe light instead of the longnose with the click switch. My click switch was mounted on top of the housing. 35 years ago as I was mounting it I had someone replace the cloth coated wiring that was deteriorated and shorting on the housing. Since the fan was 13 feet above the floor, the click switch was inaccessible, so I removed it from the housing and mounted it on wall. I have loved living with this fan for 35 years and now am moving it to a new house. In the process I have lost track of which wires go where. With switch separated, I have four wires coming to the unit. Do you have any videos of working on the inside of the housing and wiring? or know where I can get wiring diagrams? I am not that familiar with DC motor operation. Thanks I think yours is beautiful, nice job. Bob
Hi Bob! It’s great hearing about your 45041. The wiring for these is really quite simple. The armature and field windings are placed in series. Ie, power will flow through all 4 field coils, then on to one of the commutator brushes and out the other. If it runs backwards, swap the two commutator wires around. Needless to say, make sure it’s run using a full wave bridge rectifier to provide a stable DC input voltage. You can search my video uploads to see a bench test of this motor that shows the wiring in better detail. Would love to see a video of yours once running.
Derek, the only other video I can find is (Emerson 45041 Antique DC Ceiling Fan Restoration Progress) is that the bench test you are referring to? any information on rewiring the resistance coil?
@@BobDittrick Yes, that's the bench test. As for the resistance coil, I used Kanthal wire instead of Nichrome. It has higher resistance-per-foot. For the turns on the stack, High to Medium section has 18 turns on each asbestos plate for a total of 36 using 28 gauge Kanthal wire. The Medium to Low section has 34 turns on a single plate using 32 gauge Kanthal wire. I know TH-cam is cagey about posting links, but if you Google Emerson 45041 you will find an AFCA forum post with this info.
@@dereksantiquefans5049 Thanks Derek this information has been quite useful and inspirational. I've decided to go deep and learn about this fan and DC current etc. I've joined the The Antique Fan Collectors Association. I know I will have many questions and a steep learning curve as dive into the unknown (taking this fan apart). I'm hoping the forum will help me find the parts and knowledge I'll need to be successful.
Lovely! That is the stuff of dreams for sure.
That is really nice! You did such a great job on the speed coil rewind.
Awesome job! Came out great!! Very neat fan!
Stunning!
Lovely!
