Hey guys, just picked up a robbins and myer list number 2706 fan with the 5 brass blades. Some previous owner snipped the cord on it, so I would like to replace the cord and the bottom felt. The brass fan blades have seen their age as well but I will keep them.Would this fan only run through a 36v power supply? I am assuming so. I will get photos when I get back to the house, here is one I pulled from image search.
>>3001583It's a 120V AC induction motor that uses a wire-wound choke coil and a resistor for medium and low speed control. Full speed bypasses the resistor. You could just run 120V to the switch and run it at full speed.
>>3001591It's not 120v it's 32v
>>3001591>induction motorI sort of doubt it>a choke and a purely real resistive element?I doubt it.>>3001662Since you already know some of the specs, what more can you share?I suspect the thing might have a universal motor and several capacitors to achieve different speed settings while only consuming reactive power.>>3001583If you're asking wether a 32V rated fan will run on 36V without damage: It is very likely so.It would be great if you could confirm either the motor type or at least if its AC only, DC only or universal. >power supplyThe most simple power supply you can have for a low power appliance such as this is a humble old transformer, either find one that matches or wind one yourself. Rectifier if DC is a must. Or get the 36V PSU you seem to be eyeballing.
seems to me like thered be a lot of overlap with a antique lamp repair supplier. those fags are all about reproduction electrical shit
>>3001671Not OP. I googled it for you and that model of fan used a 32 volt DC motor.
>>3001583>32 V motor on 36 Vit can run, but will drain about 25% more power. i cannot tell how much will the motor, bushings and general design hold. old appliances were designed with sufficient overkill generally, but if it holds somewhat personal value, I wouldn't personally risk it.
What kind of power supply do you have?Most have some voltage adjustment.
>>3001699Well that's good news! Then I'd either get a PSU or a transformer with rectifier.Idk why OP suggested 36V but if he's eyeballing one of the chinese cheapo things (they are absolute and hazardous trash but very common) those usually have an adjuster that allows for a small range, certainly from a nominal 36V down to 32V.IMO its neater, safer and looks bezter to just have a transformer and rectifier.
>>3001583>buy cord>open bottom>white to silver, black to gold, green to ground>simple asthis fucking shit is not hard you chucklefucks
If it's a DC or universal motor it should also sort of run on 12V for testing, set it at max speed
>>3001779Yeah, sure. Take a 32 volt DC motor and wire it directly to 120 volts AC. What could go wrong? Fucking moron. Jesus Christ. This fucker votes and probably has a dozen kids.
>>3001779120V AC32V DC motorwhat could go wrong?
>>3001583why compels people to snip the cord on electronics?I see it all the time
>>3004150>snip the cord on electronicsits something to do with the mk ultra mind programming targeted at boomers in their youth. my geriatric mother neurotically cuts the cirds off anything powered she throws out while babbling about>recycling saving the earththen she hordes baskets full of cut up chinkcords so she can donate them to some poor struggling fortune500 entity that offers her a 1/33rd of a shekel participation coupon for hauling trash in as an excuse to bilk old people into patronizing their brick and mortar storefrount
>>3004150>>3004195My bet in this case is that some interior decorator wanted to use it as a static decor item without having to deal with the cord. It's possible that they had safety/liability concerns about it being usable too since some dumbfuck kid could get his fingers lopped off pretty easily with that thing.
>>3001662No it's not. It's 120v. There is no utility on this planet feeding a house 32v dumbass.
>>3001583If the motor is really 32v, then it already has a built in power supply/transformer to take the 120v incoming and turn it into 32v. Just replace the wire.
>>3004255>>3004256Hahaha, god damn are you fucking ignorant. Stay in school kids.They didn't put AC to DC power converters in 100 year old desktop fans. You know what they did have? All sorts of weird power standards across the US. How did they handle that? By tailoring their products to use whatever power was available in a specific area. Wiring a motor to operate at 32 volts from the factory is easy as fuck for these old school motors. They weren't efficient but they were dead simple and easy to adapt.Since every region had its own power plant operated by an independent company their line power could be fucking anything. Sometimes it wasn't even a 'power' company. It was just the local factory or mill selling excess generation to the locals. Mostly their generators powered lighting systems or motors. The voltage they used depended on what was best in their specific case. Did they use Westinghouse (AC) or Edison (DC) products? Fractional horsepower (e.g. sewing machines) or larger motors (e.g. engine lathes)?Or sometimes not even that. Some people had completely battery operated systems that were charged by an onsite generator a few times a month. Back then lighting was the biggest user of power and batteries were expensive a fuck. They were still cheaper than using an always on generator that could handle variable loads but they weren't cheap. Wire was expensive too. You could power the system at 6 volts DC to save on batteries but then your wire would need to be fucking huge. Or you could power your system at 100 volts DC but then you could need a fuckton of batteries because most batteries could only store 2-3 volts.Fuck man, old appliances used to use Edison screw terminals so you could plug them into light sockets because that was all anyone HAD. Power outlets weren't a thing yet. So, yeah, some appliances used weird voltages. That fan was likely meant to be used on a 32 volt DC system that was battery powered, not wired into the electrical grid.
>>3004326To continue. The two-prong plug we use today? The first version of it didn't come out until 1930! Edison's first power plant that sold power to the general public opened in 1882. 48 years of people doing whatever the fuck they wanted in terms of connecting things other than lights to the power system.If anyone wants to see how the did this shit back in the day (1926) check this out: Graybar Electric Company Catalog No 101https://archive.org/details/graybarelectricc0000unseIf you wanted to start your own power company this was the catalog you bought everything from. 743 pages illustrated. Picture fucking related. Anything look familiar?
>>3004326>>3004327This got me curious enough to look into 32V DC systems and where they were used. As you say they were usually battery powered and it sounds like they mostly existed in rural areas, especially farms, where they'd use generators or sometimes windmills to charge the batts. Apparently this lasted surprisingly late, with 32v stuff being made into the late 40s, and they'd often wire stuff to 110 standards (of the time, anyway) and use standard plugs and sockets so they could just hook up to the grid when it eventually got to them, which has led to a lot of burned out radios and other stuff in later years because people saw a normal-looking plug and stuck it in a 110 socket. I wonder if that's why the cord has been chopped off of OP's fan.
>>3004328More likely the insulation on the cord went to shit and they cut it off so no one would try and plug it in. They used cloth, rubber, or even asphalt insulation back then and it simply falls apart after a while even when stored in good conditions. It also likely would have had an Edison screw type plug on it like the toaster pictured here >>3004326.
