monty ward speed control

[Deleted]

So as most of you know, i finally got my evergo working good again, it works great but on the five speed control i have for it (see picture below) when i have it on the 5th speed it still seems a bit fast. im sure there must be some way to sodder in a capacitor or something into the 5th wire to slow it down some more on the 5th speed. heres the pic though, let me know what can be done. i dont want to blow the control or anything either, or do anything unsafe of course. its the only control i have for this fan. thanks!

You can always solder a capacitor in to slow it down. Many fans, notably cheap spinners, have 1-speed motors. Medium and Low are achieved by wiring capacitors into the system. In the 80's, Emerson's K55 motors were 2-speed, and there was a capacitor spliced into the Medium circuit so as to create Low. For all I know, it's still that way.

Anyhow, just make sure that the power ratings are all in-sync (voltage and amperage and such; also, remember that Volts x Amps = Watts). Make sure you solder it properly, and all that jazz. Capacitors have a rating, it's the number of microfarads of capacitance they can store. The symbol is "µF". See here: en.wikipedia.org/wiki/Farad

The µF rating will determine, ultimately, how slowly the fan turns.

One thought: you may be better off soldering a stronger capacitor onto the full-power (High) circuit, and wiring it up to pass-thru the 5 setting. If you try to splice a capacitor into the 5 circuit, you can run into bigger issues. From the standpoint of electrical safety, I'd say to wire directly into the hot line.

I would leave it original. You can definitely do it safely but it's a lot of work and modifcation and the fan basically performs like it should originally. If you want to, you would un-solder the wire on the far right and cap it off. Solder one end of the capacitor to that terminal, attach the other end of the capacitor to the hot lead going to the fan, which is also the left-most screw terminal in the picture.

the most left screw in the pic is the black wire if i remember right? looks like it. sorry im too lazy to remove the cover again lol

There are two black wires. You'll want to connect it to the one that connects to the output side of the transformer.

oh yeah thats right i forgot they were two black ones. i get it now. what if you mix the 2 black wires in the wall box?? like, do they have polairity?

[Deleted]

it doesnt matter if you mix them in the wall box but it does matter which one you connect the capacitor to.

[Deleted]

yeah i never messed with the wires connected to the capacitor.

There is no capacitor in the control unless you add one.
