Miele vacuum cleaner broken motor power controller repair. Miele stofzuiger reparatie motorregelaar
In a previous video on this subject, ua-cam.com/video/ELDUTiepPQI/v-deo.html
I showed how I cleaned the clogged fan of this vacuum cleaner but then a new problem emerged: the motor power controller turned out to be broken.
Initially I couldn't find the triac (triode for alternating current), the electronic device used to control motor power, but eventually it turned out to be in the motor housing. After replacing the triac, the vacuum cleaner worked fine again. There was also a problem with the cord winding mechanism, but that was easily resolved by placing the end of the winding spring back in the reel.

In een eerdere video over dit onderwerp ua-cam.com/video/ELDUTiepPQI/v-deo.html
liet ik zien hoe ik de verstopte ventilator van deze stofzuiger schoonmaakte, maar daarna bleek er nog een nieuw probleem: de motorvermogensregelaar bleek kapot.
Aanvankelijk kon ik de triac, de elektronische schakelaar waarmee het motorvermogen wordt geregeld, niet vinden, maar uiteindelijk bleek deze in het motorhuis te zitten. Na het vervangen van de triac werkte de stofzuiger weer prima. Ook was er een probleem met het snoeropwindmechanisme, maar dat was eenvoudig op te lossen door het uiteinde van de opwindveer terug in de haspel te plaatsen.

Miele vacuum cleaner suddenly makes tremendous noise. Miele stofzuiger maakt ineens enorme herrie.
Переглядів 1,7 тис.Рік тому
Miele vacuum cleaner made a tremendous noise after we used it to remove old carpet residues. I assumed the huge noise was caused by motor imbalance due to clogging of the fan. The holes of the fan indeed turned out to be clogged. I used a metal wire to pierce the holes and cleaned them further with a cotton swab. After that, the vacuum cleaner worked perfectly again and was quieter than ever. E...

Gamma radiation reflected from aluminum block : Compton backscattering

      Hoe reageert de motor op draaien aan de knop van de motorregelaar ? Heb je hem ook al eens rechtstreeks zonder regelaar op 230 V aangesloten? Het heel even snel draaien zou nog op een gammele verbinding of printbaan kunnen duiden. Ik denk niet zozeer aan de triac want bij een kapotte triac draait hij op vol vermogen. Het zou nog wel het regelcircuit voor de triac kunnen zijn of de potmeter van de draaiknop. Maar ga niet teveel af op mijn opmerkingen, ik ben medicus en hobbyist, geen vakman op stofzuigergebied ;)

    Good video! It's worth noting that pancake GM tubes are calibrated to 662 keV gammas, and will over respond to sub 200 keV gammas including the 60 keV gammas emitted by am241. So the device is still probably over responding a fair bit, but it does give you a reasonable rough idea of the correct does rate. It's also a bit weird to measure dose rate on contact, measuring it from a couple feet away with additional calculations to correct for the over response would give you an accurate risk assessment of the external gamma rate (which is almost zero). Of course special precaution should still be taken for Am241 foils, as the internal dose is extremely high, so not messing around with the foil and preventing contamination is the biggest concern.

    • @AJApper
      @AJApper Місяць тому

      Als de triac kapot is blijft hij in geleiding en werkt de motor dus op maximaal vermogen. Bij mij bleek de motor met de triac in positie al te draaien op 10 V gelijkspanning, wat mij onmiddellijk had moeten leren dat de triac kapot was. Een triac hoort niet te geleiden bij zo’n lage gelijkspanning. Hoe de triac er van buiten uitziet zegt niets over zijn functioneren. Als je de triac unit verwijdert kun je de motor aansluiten op een lage DC of AC spanning en kijken of ie goed is.

      Yes, it does. However, Ra-226 decay is more complicated than Cs-137 and Co-60, generating lots of peaks in its gamma spectrum. Apart from the famous Pb-214 peaks at 242, 295 and 352 keV there are also Bi-214 peaks. They all will generate their own backscatter peaks, Compton continuum and Compton edges, making it difficult to interpret the spectrum. Nevertheless, a higher than usual backscatter peak due to gamma ray reflection in the aluminum block might occur, but it might be obscured due to the many other peaks. I did not test this. I thought it would be better to look at simple isotopes with clear photo peaks.

      Hi Lorenzo, a Radium-226 source not only emits 186 keV but a lot of higher energy peaks also, the famous 241, 295 and 352 keV from Pb-214, than Bi-214 at 609 and 768 keV and Pa-234m at 1001. That is why you measured a low factor. Ra-226 is a component of the U-238 decay chain. Radium-226 is a difficult source to use in this experiment because its decay involves so many different gamma energies. It is easier to use an isotope with one prominent photopeak.

      @@Telyron Mean value is not useful since µ value declines sharply with increasing gamma levels. Thus the effect of the higher gamma energies contributes more to the measured attenuation value. Besides, I forgot to mention their are a lot of peaks in the gamma spectrum of Radium-226 above 1000 keV arising from Bismuth-214 : 1120, 1238, 1377, 1407, 1729, 1764, 1847, 2118, 2204, 2293, 2447 and 3053 keV.

      It is only a 10 K potentiometer and a switch. You can buy them everywhere.

    Awesome video! I finally got a 1" NaI:Tl GammaSpectacular spectrometer kit, and I use the PRA software with it! It works great, even though the efficiency is lower, since I'm using a smaller crystal. I'd love to try CeBr3, from Berkley Nucleonics, but it's so expensive! HPGe would be the best of the best! I was able to identify Kr-85 (514 keV) from some old Western Electric electron tubes, ca. 11/1973, 15 μCi, which both only give me about 500 CPM on my Inspector USB Geiger-Müller counter, now that the activity is only about 0.637 μCi, 49 years later. I'm going to try Pu-239 next (17.1 μCi, total) from old Soviet smoke detectors, to see if I get any of the low-energy gamma energies, like Am-241 and _maybe_ U-237 from Pu-241, which undergoes β- decay, which emits very low-energy-about 20 keV β- particles, and on occasion, α decay to U-237. The problem is that plutonium isotopes have low branching ratios for gamma rays. It's easily detectable up close, with my Inspector USB Geiger-Müller counter, however, a sheet of paper blocks _almost_ all of the radiation, being mostly α particles. Even my CD V-700 on "X1" only goes up to about 100 CPM (β and gamma) per source. I was able to detect some gamma energies from my trinitite, but at a lower efficiency, since your NaI(Tl) crystal is twice the diameter of my detector. Anyways, _excellent_ video on my favorite hobby! I'm glad to see when you post a new video, as they're very well done! You're a smart man, and your methodical approach is paramount! Very well done! Thank you for making this! Have a Merry Christmas and a Happy New Year! 👍

    Does the machine control the speed of rotation? Can you make it spin way slower?

    • @AJApper
      @AJApper Рік тому

      Yes, it is a rotating magnetic field. Perhaps lowering the voltage will slow the rotational speed, but I did not try. Depends on the circuitry. Realistic speed will be difficult ;)

      @AJApper Рік тому

      I did not try with IN-16 tubes. Voltage will be the same, but I assume mA value should be a bit lower, start with 3 mA burning current at 170V.

    Thanks. It's ridiculous that the temperature isn't controllable from the factory when they intend the pump to serve many ales, all with different ideal temperatures. 🙄

  • @jimgallaher458
    @jimgallaher458 2 роки тому

    I've installed this hack, but when the temperature display is over 3C the fan (and cooler ?) continues to run, is this normal ? Surely the PD machine is factory set to cool to 3C and if you change the NTC resistance it will only make the machine sense a higher temperature and try to cool it ?

    • @AJApper
      @AJApper 2 роки тому

      The combined resistance of the NTC and the potmeter determines the PD's cooling behaviour. If the NTC resistance declines, due to increasing environmental temperature (remember, NTC means negative temperature coefficient, the higher the temperature, the lower the NTC value, also demonstrated in the video) the PD starts cooling until NTC value rises and resembles 3 gr C. But we artificially add an extra resistance, the potmeter, and thus are able to shift the setpoint for starting the cooling to a higher temperature. The PD senses a higher resistance value and thus "thinks" temperature is low enough and cooling is not necessary. This way beer temperature can incline to 7 of 8 degrees before cooling starts.

    I am using Radiascan 710A, however when measuting Am241, covering with sheet of paper of even a thin plastic, there is half of uSv/h still coming. I thought this would be gamma, but the thing is, as soon as I put the beta shield on, there is almost 0,5 uSv/h registering, so very low alpha. Does this mean there is some beta radiation coming out of Am241?? Or is it gamma, but it is just so weak, that it cannot penetrate even the beta shield? Thanks for any advice. Tried to google this, but couldn't find answers, why Am241 could be emitting beta radiation or if the gamme can be so low it cannot penetrate even a thin plastic cover.
