The effect you are seeing there is the capacitive effect, That motor does not have a capacitor start just the start winding which is switched in and out by the centrifugal switch. You cannot test the winding insulation without an insulation tester (megger).
At 2:31 you seem to have a short circuit, I don't see you touching the case with your probes. Don't touch the case or probe tips with fingers when measuring. Recheck by measuring the resistance between the case and the external black wire (which you would connect to the mains supply). Then do the same for the external mains red wire to case. Measure the resistance or continuity across the red cutout (should be short circuit / beep). Measure the resistance / continuity across the centrifugal switch contacts (closed / short / beep when motor stationary). Operate the centrifugal switch manually and check contacts open (you may see a slight resistance change). Your meter seems to show I (infinity ?) for open circuit and something else if there is a resistance (in horseshoe mode). Use fused breaker / RCD when powering up.
No good without the capacitor as TechGorilla says. Try a 1100Uf 1000v cap from RS Components. You might get the data and circuit diagram for a 70's washing machine online. I do not think I have any of these motors left on my shelf, as I used to use them to power Meccano Models years ago. I will look in the shed in daylight, you never know.
Hi Adam, 1/4 hp = 180 watts, there is 720 watts to 1 hp. There is no short there if the bearings are ok , make sure the wire's are in a good condition no splits or bear wire's showing and no melted insulation ,that motor should be good to go , have fun
I can't remember seeing a capacitor on my shearing motor. certainly not on the outside anywhere. I don't think it needs one. use some threaded rod. connect it up with a light fuse in the plug stand back and see if it works. You aint got much hair so it won't matter if it stands straight up.
As Jagracershoestring609 has said. AC motors need a capacitor to run. They are very often affixed to the body of the motor. If you can't find one already wired into the motor, I would investigate getting one. They are usually a metal can looking device. either round or sometimes oval shaped with electrical connections on one end.
You should clean up and reuse the old bolts that hold the casing together ideally one in bottom left and one in top right that will hold it together for a test run (always make sure the shaft rotates freely when tightening the bolts) add some temp wires and try it! Mine worked perfectly😎
People say it should have a capacitor but on mine with the centrifugal governor it doesnt have one - yours looks like it never had one too, i have a hoover motor which has a cap which must be newer but not looked inside yet.
Your lekky skills are about the same as mine 😂 Horse shoe mode 😂 (ohm's) Motor seems ok to me, id have it plugged in by now as patience isn't in my repertoire 😂👍🇮🇪
You ideally need to have the meter on the correct range for each measurement. You appear to have a winding shorted to chassis, technically it is almost certainly cattle trucked. Edit..you seem to have accidentally shorted something earlier. NONE of the windings should have any path to chassis/earth. Some of the reversible old Hoover washing machine motors use a phase shifting capacitor. The rotational speed is related to the FREQUENCY of the mains supply and the number of poles in the motor. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 - for the number of seconds in a minute - by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has:
As far as I know - from listening to UK creators - is that anything that sucks is naturally called a Hoover. That's just a joke, people. Get 'yr knickers out of a twist.
Yep in the UK we normally say get the "hoover out" as its quicker than saying "vacuum cleaner out". Also we do the hoovering ot many refer to it as vacuuming. We like to save on words why use two when one will do. Note politicians do not follow this rule 😂😢😅
This. Plus, this motor has a centrifugal starting switch like a US dryer motor. The switch keeps the start capacitor in circuit until the motor reaches enough RPM to pull the switch weight in and break the contacts.

I have one of these and it still has the original capacitor and is working perfect.
Love it.

PUT IT TOGETHER PLUG IN YOU WILL SEE IF IT WORKS LOL
EXCACLY HOW FRUSTRATING

its good/ motors multimeter reading looks good to me/ switch is good too
When you got a reading off the black wire the switch was on mate. When you tried black again it was after the switch test and your switch was off.

Stick a plug on it and plug it in, it's got two chances!

All looks good, it's very clean and looks in nice nic, bung a plug on it and fire it up see what happens. Bet it runs fine

Chuck a plug on it red live black neutral and green earth switch it on shit or bust what I’d do anyway

If you are worried, leave it until the one from your mate turns up and check to see how that one is set up. put yours together the same way.
Your motor is ok Adam
As the guy from scrapy racers. Proper job
Adam you’re trying to be to technical. Chuck a new wire on and plug then connect to mains. What have you got to loose. Nothing. Excellent 😀
Use the old bolts,Wire her up and let her rip…Plug it into one of them thar RCD plugamyjigs for added safety…all looks good from here 👍
Your lekky skills are about the same as mine 😂

omg could of put a plug on it and plugged it in less than half time it took all this faffing about as you wont be any wiser after all
I might be misunderstanding, but you're testing the windings to ground. I'm not sure why. Why not test across the windings proper?

Yes that's good bud means no shorts
