Help me. Ps this is the second motor in two days from harbor. Freight Smith and Jones 3hp

Thank you SO much for posting this video. I have an vintage sewing machine that is not starting up when I plug it in. Hopefully it's a short in the wires or wires not connected properly and not the commutator/aperture.

Excellent video. Going step by step....again....again. Most youtube videos skip basic steps like setting multimeter before each test and you have to go back to beginning to see what is the multimeter set to . Same thing with measurements....taking two measurements after each other is perfect and enough to show roughly the same reading. Nice work, LabOtomy ! :-)

I got resistance spike in bar to bar, can it be fix?

I was out driving my 1944 GPW ford jeep. I noticed the amp meter was not working, reading zero. I decided to head home as i became worried. The amp meter needle then moved into the negative side of the guage which indicaded the battery was been drained on energy. After a while the needle moved to show a positive charge. i thought ok, all good, jeep has fixed itself. 😅👌🏻👍🏻. As i continued along home, suddenly the amp meter went totally crazy. The needle was flicking from side to side, the higher i reved the engine, the more violently the amp meter needle flicked from side to side. 🤤😓😭😭. I made it home ok. My jeep has a 12 volt system. New external voltage regulator & battery installed 3 months ago. I didn't know what to do or where to start. I found your video , thank God. Removed the generator/stripped down. Generator internals were filthy/full of dried dirt/dust as if it was dropped in mud for 6 months, then installed in the jeep. Probably dirt from world war 2, 😅🤣. Completely cleaned the internals with contact cleaner aresol, housing/armature/commutator. Surprisingly the 2 brushes had probably 60 to 70 % left.. Cleaned commutator bars where the brushes make contact with 800 fine grit paper. Commutator bars came up like new. Filed the brush surface that contacts the commutator bars with a file, so it was flat for better surface contact with the commutator bars. Done 3 tests on the armature as per your instructions. 2 ohms & 1 continuity tests. Armature passed the tests with flying colours. I assembled generator/ installed in jeep, left the fan belt off the generator. To test the generator, i connected a wire between field terminal & armature/dynamo terminals on the generator . I then ran a 2nd wire from the positive side of the battery to the wire that connected both terminals on the generator. The negative lead must be connected to the battery. The pulley spun on it's own indicating it was working properly. Connected up wires, started jeep engine. Reved the engine to approx 700 to 900 RPM, amp meter needle moved across to the positive charge on the amp meter. Tested battery charge rate was 14.2 volts at approx 700 to 900 RPM. All the problems were caused by a gut full of dirt in the genny, 😅🤣😂 Thankyou for sharing your information, really got me out of trouble. 😂🤣😅👌🏻👍🏻👏🏻👏🏻👏🏻 Cheers from 🇦🇺

If you measure no bar to stack leakage on the first bar, shouldn't that conclude the test? Any leakage from the windings to the stack would show up on all of the bars.

@TheLabOtomy

The growler is a specialized device, so will be faster helping validating the quality of an armature insulation for eventual shorts... this said, being specialized, means it is less common than a standard multi-meter in a work-space... with the multi-meter, I also like to confirm the balancing of the coils, not sure if the growler can deliver on that (leaving the last open for any growler specialist to infirm/confirm on that statement)

Great Video! I have one question. In the first testing you had appx. 01.6 ohm and you said that there is resistence drop? How do you indicate that? For examle if you measure it and it jumps right away to 01.6 ohm instead of droping from 34.6 to .01.6?

@chrisbart5316

2 жыл бұрын

I am not the author, but I am an electronics technician. The rate of drop is immaterial, as it is a function of the circuitry in the meter, and also any residual resistance at the contact points. Just wait, and use the reading when the meter settles. The term "drop" as applied to this test is about the amount of resistance in the armature winding, which will cause a voltage drop when power is applied.

Great video - has got me thinking! Hi, testing a 6-pin universal 2-pole Bosch washing machine motor (Bosch front loader). The motor had previously seized due to a failed armature bearing. Replaced both bearings on the armature. I then checked the motor for continuity through windings, thermal fuse, to the carbon brushes and through the tacho - all appeared good according to the DMM. So, reinstalled the motor in the machine and tested, but now the motor fires up and spins the drum as you would expect, but only for just a second or so before it stops (this happens for wash, rinse and spin)??? Could this be a commutator issue as per your tests above or would any failings (shorts) here cause the motor not to spin at all)?

You can Definately rewind the wires and use it again. The main problem isn't burnt wires, but the alloy, assembly itself, if it's still in good shape. Electric motors usually have an air cooling fan to them. Sometimes a heat sink or heat resistant shroud , thicker wires can pro long their use. How they short outs, perhaps small metal debris,melted resin, from heavy use .

That's a quality tutorial

Hi John, 1) for the 180 test, value itself is not important, consistency is. I usually mark on the commutator the start and 180 position and check every time I have landed on the right slot. 2) For the bar to bar test, go 1 to 2, 2 to 3, 3 to 4, etc The idea is to check if their is unbalancing across the wiring, which indicates an issue impacting the engine to properly turn. 180 test or bar to bar is simply to make sure a similar portion of the wiring is checked every time. Hope that clarifies.

You can run this type of motor on a very low d.c. voltage to test it. A vacuum cleaner motor wil run on 9 to 12 volt d.c.! The rpm is of course not high than. Be careful and do not connect it to a car battery. Dangerous when short circuit! Vacuum cleaner motors without electronics in it to change the power of the suction, you can supply direct on 9 volts to get it run. Try it yourself.

Best video on this topic. And a nice disclaimer. My field is black and has almost no insulation left. The armature has one suspicious coil. All of them are 0.3 to 0.5 but one is 0.6 , could it be normal or could this even be the reason why the field overheated? I dont know nothing obout the provious use of the mashine. It's a 15yr old dewalt but the blade was pretty dull.

@TheLabOtomy

So, a possible scenario in your case could have been: 1) Blade is dull, which causes 2) Motor to have to work harder, which causes 3) Motor to pull more amps, which causes 4) Armature coil to heat up beyond normal, which causes 5) Damage to the internal wiring (resulting in resistance discrepancy within the machine coils, 0.3 to 0.6 is a 100% variation which is real source of concern) and degradation to the insulation material (burning through and truning black) 6) Which causes the motor perceiving a loss of power to go back to 3) for a ultimate catastrophic failure The Cause and effect theory at its best!

Hello. Is 1.5 Ohm usual for all motors? Should I only have a current flow of 180 °? Installed in the motor, it is not easy to identify the correct contacts. I am using a metrix MX 355. An ammeter with a combined flow test and ohmmeter. I measure a flow of 4.3-5.3 ohms between many contacts. Do I have to measure all opposite contacts? So far I have found a pair of opposing contacts with no flow. The carbon contacts are as wide as two contacts on the armature. I have the problem that a Sebo Felix vacuum cleaner with Ametek Italia e063200099 1200W motor with good long coals suddenly stopped working. When I put the motor out of the device, it ran sometimes. But not always. Like a loose contact. But one thing is certain, it is not the supply lines, they also have power when the motor is not running. I cleaned the contact surfaces of the anchor and the coals with a bath lime cleaner with sulfamic acid and then solvent, and tried again. Same as before. I can't say whether the "fire" is stronger now. But it seems very strong compared to the Wikipedia video. Is the engine over and need to be replaced? Because a replacement anchor (if it were) is probably not available for purchase. If I make the effort to pull the sheet of the fan chamber down, I could remove the anchor. If I knew where I could get a replacement engine ... Also used. For example, with the names of other devices that contain this motor.

@TheLabOtomy

4 жыл бұрын

The idea of the 180 test is that you cover the same wire length each time, hence the need to choose consistent pairs of commutator contacts. Any variation around that test is an indication there may be internal shorts and would require either the armature to be replaced or serviced/rewired (specialised work).

Thanks Master

Any experience with a starter that engages but seems to not have enough power to actually move the engine? Already checked for a bad ground, and all connections related to the starter and solenoid. Verified there is no weak connections. Solenoid contacts switch as designed. Brand new battery 2 days old. 2nd battery by the way. Lights dim big time as the starter engages then stops, as if the engine is seized. Ran fine the day before this issue arrived. lol Woke up to leave and discovered this problem. I have not removed the starter yet. But I do suspect possible armature burn and/or brush damage. Just not sure if one could cause such a MASSIVE power draw like this while never turning more than what seems to be an inch or two at most. Could I be experiencing a less common commutator-armature stack short?

Before I start spraying lube into to cylinders anyway. lol (oil light never came on, but I found I was abnormally low on oil.) NEVER heard any ticking or noise from the engine at any point.

One thing is certain, I can not get the engine to rotate even when trying to push it using all gears. I get the rear tire sliding only. Granted, I am not on the bike while trying to "push start" it. Perhaps there needs to be weight on the bike to prevent the tire from sliding. I have never had this happen before. And that includes my fist bike. (I was horrible with maintenance back then) It overheated a few times but never "seized" like this. This bike has been babied. It is almost a sacrilege for me to own this bike, as I never even come close to using it's full potential. Just wish I knew why it started fine that morning, but the next morning, nothing. And it is for sure the starter draining the system. I removed the starter from the circuit and hit the button. The fuel pump and all lights ran as normal. Now I am praying there is a bolt inside the crank case so I can try to rock the engine loose. (If seizure is my issue)

General question a starter motor I'm troubleshooting has four brushes each separated by 90 degrees. The brushes as 12 o'clock and 6 o'clock are positive and brushes at 3 o'clock and 9 o'clock are negative. If the armature windings terminate at commutator segments that are 180 degrees apart. How is there current flow? It seems like both ends of the armature windings would be at the same polarity at any given moment. What am I missing?

Commutator segments are not, per se, connected on a 180 degrees direction. It all depends on the motor so can have many different configurations.
