Dual Voltage Motors, How They Work, And Wiring Them Without The Wire Labels. #059

How Dual Voltage Motors Work, and How to Wire them even without the wire labels. I have received several requests to cover this topic.

I've looked at a thousand vids on this subject and yours! FINALLY! I get the complete picture! Thank you for this wonderful explanation.

There are so many forums wherepeople argue endlessly about the merits of running a tool at 240 instead of 120. Some people claim that beyond the reduced amperage consumption, wired at 240 the motor will have a higher stall torque and thus will be harder to bog down and run better. I think it would be a great video if you tested these different theories. I have seen lots of talk about this topic but not a lot of proofs lol. Thanks for the great videos, keep it up

This is by far the most simple explanation about a dual voltage motor which a person with zero knowledge on wiring a 6 lead motor. Thank you so much!! My late dad left us a vintage thomas sprayit compressor. Looks like im gonna try to revive & use it. 👍👍👍

This video is incredible. I’m literally watching this at my job. You’re saving the day right now

I have been wanting to convert my grandpas 1959 Dewalt 925 over to 220 and I never understood what the wiring chart was showing. The way you explained everything I can not only do it but I can understand what i am doing. I was always one of those little kids that said "but why". Thank you so much for telling me why. You are an awesome teacher.

Great job as a old time retired factory maintenance man your presentation was both spot on and very well demonstrated. I get frustrated with people on the internet comments saying there going to lower there machines 240 instead of 120 to save money please go over billing for kilowatts WVA thanks

Jeremy, you saved my butt! You have definitely earned my subscription! I bought a used motor only to get it home and discover it turned the wrong direction and was "non-reversible". It was also a dual voltage motor, but I did not know why there were six coil wires rather than the four I was expecting, and two of those wires were soldered together! Thanks to your video, all was revealed, and by desoldering the wires that were soldered together I was able to identify the two run coils and the one start coil. I switched around the polarity of the start coil, soldered things up, and put it all back together complete with new bearings. It now spins the direction I need and purrs like a kitten!! Thank-you so, so much! I am currently building a 20 inch bandsaw using plans purchased from Matthias Wandel, and wanted to use this motor to spin up, and test the saw. The motor is 1.5 HP and spins at 3450 rpm. With a 2.5 inch pulley do you think it will spin too fast to be used long term? I can see that you use a 3 phase motor on your saw. I am curious what the power of that motor is, and how many feet per second you run your blade at? Many thanks!

Your helping many women and men put food on their tables of their families. God bless. Thank you.

Just completed a rewire on a Dayton 3/4 hp dual voltage motor from my Dad. Needed to reverse the rotation direction and keep the wiring at 115V. This video gave ALL the information needed. Jeremy, you are a wonderful teacher. Keep up that good work!

Learn something new each video on this channel. So cool.

I have an 3 Phase Induction motor with dual 230V 460V something like that and wandered how i will wire it for a VFD to DIY build a test bench to spin VE type diesel pump at 600 RMP and 2200RPM the IM is rated at 1400 RMP thereabouts, i'm hoping the VFD will get the RPM up. Australia is 240V standard house 10 amp.

Plus use it to drive a pump to run waste veg oil through centrifuge at 90-100 psi.

All this stuff is way over my head but with your help from the videos i'm learning and getting confident that might be able eventually do it. Thank you so much cool channel. Great minds that surface on the internet now days is amazing.

I’m about to graduate as an electronics engineer and I just found your videos . The few videos I’ve watched so far I really enjoy learning with you m!

[cumon]

thank you so much - I got an old 1947 delco 1.5 hp beast - repulsion induction motor with no specs and needed to figure things out - this helped so much. You explained it so well and you are well organized. You put so many of these you tubers to shame on tutorial videos - very awesome

[robbybachmann]

Thank you for helping me learn about electricity and motors. You are a good teacher.

[matthenard]

Thank you so much, accidentally ripped the cord out of my motor and couldn't figure out how to wire it, thank you for the education and walk through, you saved me a lot of headache!!!

[geoben]

Well done. Great explanation without any distracting music or foul language.

[vandal]

First good explanation I've ever seen, thank you.

[desireeblackman]

Fixed mine. It was the thermal switch! Thanks!!!!

[chrisshaw]

I hope these vidz get you paid mate cos honest, you must be the only guy Ive seen on YT who can actually portray a moderately complex subject in simple terms that people can follow and understand, muchas gracias

As a former HVACR tech this is exactly how we were taught to find which set of terminals was the start winding and run winding on a single phase compressor*. You may know that most refrigeration compressors wired for single phase and under 5 HP (More or less depending on the manufacturer.) have three terminals. The highest resistance value between any two terminals is both the run and start windings as those are connected together and will make a circuit, the next highest is the start winding and the lowest is the run winding. A good reminder of of how to find the correct windings on a single phase compressor. *Refrigeration (Includes Air Conditioning.) compressors are often totally sealed units, they are an electric motor and a compressor combination.

Thank you to both of the Jeremys! I just rewired my lathe which can with a dual voltage motor for 110!
