Just purchased a Leeson M009086 Electric Motor 1/2HP 1725 RPM 115/208-230VAC Single Phase for my lathe and want to be able to wire it to a Dayton drum switch. The motor has 7 wires and I would like to see a video of how to wire the forward/stop/reverse switch. Great video!

[@Peter-ds2gb]

Great video thanks. I am installing a switch on a Leeson 1/2 hp motor and the wires are all black and marked with the P1 and the other Ps , not colour coded. Is there a schematic how to wire the switch without the colours.

[@bigmedge]

Sorry but at the end, how did you check it for ground ? I probably missed what actually happened, but to me it looked like 1 alligator clip was connected to the ground receptacle prong & the other to a motor ground

[@ebachy]

Good video. It helps to have the motor's schematic for wiring. I have a 220V 60 hz single phase induction motor that draws 1.4 Amps. The schematic on the case shows there is only one direction of rotation. It does show it has terminals for 3 speeds. I can easily add a DPST switch to get it to run at any single speed I choose by connecting one pole to the start/capacitor wire and the other pole to one of the speed terminals. I would like to find a second switch that I could insert downstream from the DPST switch so I can select between speeds on the one power leg. Where would I find a single pole triple throw switch to do this? I see SPDT switches that could provide connection for two speeds, or I could wire three SPST switches downstream and just label them so I NEVER have more than one switch "on" at a time when I flip the DPST main switch (seems like asking for trouble!)... Certainly, a DPDT switch would give me two speeds... Any other ideas? I have seen ceiling fan 3 speed switches, but they seem to use voltage limits to get the different speed on a single speed motor - they have just a single hot & neutral output connections going to the motor. Thanks for your help!

Thanks for this! I have a Dayton 1/3 HP single phase with capacitor start. Trying to add a switch, but it doesn't have a P1 wire. Six yellow that are numbered 1-6, and I have them wired together per the nameplate for 110 volts, two groups of three. I have the black power wire from the cord connected to the switch with a pigtail like the video shows, but since I don't have any wires labeled 'P', I'm not sure how to finish the connection. Do I connect the white neutral to the second position on the switch AND all six yellow wires? Ground is screwed into place on the motor housing.

I have a motor on a squirrel cage, From an AC unit. It has red, white,blue & black wire's. I hooked black to hot & white to neutral. It runs but very slow.???????

How to wire a 50+ year old washing machine motor with 9 white wires numbered ABC346789 not colored leads. When hooked to power 7 wire pairs caused a hum and other wire pairs blew a tiny wire(80 gauge +/-) as a fuse link or no continuity. When the pairs blew the fuse/wire either it burned through or no reaction. It came from a Sears washer.

you just saved my day! thanks guys!!

Is it possible to convert a variable speed bench grinder to a single- speed bench grinder by bypassing the circuit board and rheostat? My circuit board fried, but the motor and capacitor are fine.

[@Cosmic_Soul]

My son has stored a heavy duty high speed grinding motor with two grinding wheels in my garage. I tried to sharpen my lawn mower blade with it. In a few seconds the blade started to burn with heat. Is there any way I can reduce the speed of the motor by installing something to its power supply?

[@patrickmccardle4233]

[@simonaurokium6258]

Hello Can someone help guide me wire my polishing machine please.

[@h3llyul]

quick question tried googling etc but cant find a specific answer... I pulled a leeson motor from a treadmill.; Only have red&black for power & then 3 smaller gauge wires black, orange, & blue that arent labelled... Internally it seems wires were prejoined as: redpwr t4 t8 orange t5 t2 t3 blue p2 black blkpwr p1 If I simply connect pwr to the red & black it does power on & spin... but I would like to know what the other 3 wires are for? Is it for variable speed or direction? The model listed is a Leeson A6k17DR23A Cat/Part #:112198-00 1725 rpm 1.5 hp option to wire as single or dual phase... I'm doing simple 110v Objective is to make this a bench grinder... thx in advance eh for pointing me in the right direction ;)

[@Cosmic_Soul]

Confusing for a person with little or no knowledge of electricals. Don't understand why the motor comes with TEN (10) wires. Can you please tell me for my own benefit of knowledge: 1) Why not install a separate On/Off switch away from the motor? 2) With so many wires sticking close to the motor, isn't the heat of the motor going to make these wires sheathing stiff?

[@billkellogg1403]

Can you do this demonstration for a 6 pin switch & a motor with reverse??

[@jonpaulison2283]

Thanks for the video

[@TF856]

Could you show how to hook up an electric motor like that with a reversing switch like a TPDT switch. Or can it be done with a DPDT?

[@larrymartin8108]

Got my Flatmaster with the switch already installed. Unfortunately, the 3/4 hp switch box was too high and interfered with the stiffening angle iron under the table. Took multiple grinding sessions to finally clear the box and screw heads on the face plate. Otherwise, the table top would actually “warp” as the top was tightened down. Maybe a video on how to correct the problem is in order?

[@StockroomSupply]

Hey Larry, I was recently made aware of this issue! Looks like Leeson has re-positioned the electrical box on their motor so now it hits the top of the Flatmaster when installed. What I've found that works really well to fix this is to put two washers beneath the motor on all four bolts. This brings the motor just far enough away from the sander it doesn't interfere with the top. The way you managed to install it should work fine also! But great idea...I'll add a motor installation video to my list.

[@larrymartin8108]

EthAnswers by Stockroom Supply I’ll look for the video Ethan. I’m not sure I understand the concept. But it sounds a lot less complicated than my solution. I always seem to find the hardest way to solve things 😁. But as you said, my solution did work for me, so onward and upward...

[@shauntucker5145]

You mentioned how to reverse it by switching the wires. how would someone take this exact set up and add a second switch to select the direction?

[@albertlagerman]

With a DPDT switch. Run the hot and neutral to the 2 center terminals of the switch. Then connect the 2 outer terminals on one side to the red and black wire. Then on the other side connect it to the red and black wire, but with the wires going to the opposite terminals. I hope this makes sense! (I'm not an expert btw) Red Neutral Black | | | DPDT SW | | | Black Hot Red

[@TF856]

It can also be done with a drum switch or a triple pole double throw switch with center off. This way you only need one switch instead of two. The third pole replaces the on and off switch. Run the power to the middle terminal and a jumper in between the other two outside terminals and to the motor.

My motor is a 110181.00 Leeson | 1 hp 3600 RPM 56C Frame TEFC C-Face (Rigid Base) 230/460V and doesn’t have a P1 cable. What other cable I can use for the switch. It only has the Ts.

[@bighead240sx]

Cool video 👍

[@MrRags43]

I completely restored a DeWalt Radial Arm Saw GW2 and took apart the motor to replace the bearings and install new switches. The motor has an On/Off switch, a Klixon temperature reset button, and a dual voltage (low - high) switch. When I took it apart I took pictures of it the best I could, however wiring it back has been a challenge. Some how when I got it all together, the on/off switch once plugged in no matter what position does not control the motor. The motor spins but makes a strange noise and definitely does not run to full power. Something is wired incorrectly. Can anyone help me figure out how to wire this motor? Frame:195 Amp:10/5 RPM: 3425 T rating: 1 hour Temp Rise 50* Winding: ME4.5JIKI I never touched the wires in the box on top of the motor casing.... I have 5 wires coming out of the motor housing: (2) whites red black green Any help would be greatly appreciated, Thank you, Matt

I have a Craftsman table saw and the wiring is messed up it has a red white and black wires coming off of the motor. How do I hook up a switch it.

[@glamourphotog7]

Great video, motor is made in China, not like in the U.S. where CW CCW is viewed from the face of the shaft. NOT your fault.

Question: I have a 1940s-50s "The Driver" 3/4hp 3ph motor on my walker-turner drill press. I have 3 wires protruding, all 3 are black cloth insulated. How do i identify these 3 wires? They are 2 hots and a ground right? I also have an old power switch i would like to use on the drill press. Switch has 3 terminals on each side, which wires do i connect to the switch? All 3? Only hot?.. Any help would be greatly appreciated!!

Is electricity affected by weather or gravity?

Do u have to connect the ground wire to a certain point or can it be anywhere as long as its touching the metal

[@deanb949]

You want to use a screw that's threaded into the motors main frame if possible. If not, use one on the termination box.

[@chriscox52282]

So just install the switch on the black wire. Seems like you've included alot of extra unnecessary stuff that complicates things for the layman.

[@UriahGiles]

You must not ignore any of the other colored wires coming out of a motor! This is especially true when wiring a dual voltage motor. There is a risk of damaging the motor, and/or hurting yourself if not done correctly. All of the steps are absolutely necessary and if the "layman" cannot take on the task and see it through to completion, then he should not even begin.

[@pamtnman1515]

[@timnewman5842]

Maybe go a little slower and watch the camera angle.

This Frank guy is an Awful teacher haha… did not even try to be helpful to Ethan. love Ethan’s videos… they are some of my favourites

Almost useless video. Hevshowedvusvthat HE KNOWS how.....didnt teach anything!

[@piecetoyou8285]

Don`t bother asking a question he does not reply If some one watching this vid,what was p1 is it live or nutral

[@TF856]

You're right. I don't see him answering anything unfortunately. Some of these KZbinrs are probably hoping that other people will answer other people's questions. Otherwise they leave comments turned off. You could always ask a misleading or weird off topic question just to see if they even read them. 😆

[@munemrabadi809]

P1 is hot line to motor

????? I guess you don't reply to ????

[@xFalconFixer]

Dude, slow down and provide better instructions.

[@TF856]

Are you going to show how to reverse motors also? Actually he didn't teach anything on this video anyway. He just did it without saying what he was doing or why. Useless video.
