Wiring a Rotary Direction Switch for a Treadmill Motor Conversion 

You followed my link or you ordered one from some place else and the switch looked the same? This same basic switch is available without the straps required to make it DT. Glad you like my videos and that I was able to help.

keep in mind it will only work if your motor is DC. This info is for wiring a treadmill motor direction switch which is DC if your motor is AC it is wired differently.

It IS criticism BUT it's constructive. I am always wanting to improve so any info on what would make my presentation better is always appreciated. I will keep your suggestions in mind, thanks!!

@@dazecars So like a couple of days after I wrote my comment above I was rewatching one of your older videos and you were using a pen as a pointer. I saw that and felt bad I said anything. Thanks for taking it well.

@@dieselwelds8645 no need to feel bad your input was constructive!!

thanks

I used my computer printer and printed it on a piece of sticker paper, then stuck it to the metal plate on the switch.

@@dazecars Ah ha! A practical and easy solution. I’m always trying to do things the hard way. Thanks Daze. You know, it’s odd how the mapping of a DPDT toggle switch to that of a rotary switch can be so confusing. But you explained it very well. I have the DC part wired up to my rotary switch. Next is the AC, relay and resistors. I have 8 resistors at 200 Watts each and 4 Ohms. That should give me 1600 Watts and 2 Ohms resistance. This is at the top of your suggested range 1

@@paulmanhart4481 your watts calculation with 8 resistors is correct, but your ohm’s calculation is not. Eight 4 ohm resistors in parallel works out to 1/2 ohm not 2 ohms. Two 4 ohm resistors in parallel is 2 ohms and 4 in parallel is 1 ohm.

@@dazecars 1/4 = 0.25. 0.25 x 8 = 2. I thought when wired in parallel, you take the sum of 1/R. I don’t have an equation editor on my phone, but it’s the summation from i = 1 to n of 1/Ri. I’ll check my equations. You’re probably right Daze. I might have missed something. Ah! It’s the reciprocal of that number. So yea, instead of 2 Ohms, I have 0.5 Ohms. Back to the drawing board. Thanks Daze.

@@paulmanhart4481 you are overcomplicating it. As long as the resisters are the same value, the parallel equation is Ω/number of resister. The more complicated equation, while it works for matches resisters, is also for unmatched resisters. So when working with 4Ω resisters two in parallel is 2Ω, three is 1.33Ω, four is 1Ω, five is .8 Ω, six is .66Ω, seven is .57Ω and eight is .5Ω. Because the speed drops so quickly wattage is not that important as I show in my video one resister was able to handle the load at 200 watts. If you really want more watts and do want to spend the money on a braking resister get more little ones and make two 6 resister parallel groupings, then wire those groupings in series, that will give you 1.32Ω and 1200 watts.

not ready made but if you are good with tiny components rotary switches can be disassembled and reconfigured to switch as you see fit.
