Excellent ! Best video for checking a motor without special equipment. I just want to say that i believe that the difference in the resistance of the cord is not a problem fot the motor itself because everything is in series so the curent is everywhere the same.

I don't normally comment or watch tutorial video this long, and fixing this company grinder isn't that important. But your video captivates me due to your explicit teaching and step by step tutorial. I felt joy learning from you and that's rare from me. Thanks a lot mr diy

Well done! We'll done my friend! Thank you for being precise and meticulous in your explanation. I would've never figured out what the issue is with my rotary tool without your help. Sadly, in my case, the commutator has 3 segments that displayed infinite resistance. In other words broken or burned wires. I'm not sure where I might find a replacement armature where I live that might be a perfect fit for my tool. I guess it's time for a new rotary tool!

Brilliant video. Nice clear explanation and demonstration. I've just bought an almost new 'Spares or Repair' angle grinder for a tiny price and tested it as per your video and identified a damages armature ( failed the side by side resistance test ). New one ordered today for a very reasonable cost. Thank you so much for taking the time to share this with us. 😊😊😊😊

So I have a orbital polisher, which in short is very similar to an angle grinder. When I try to start it, it takes a loooong time to do it and seems to do it in impulses. I have checked everything that you mentioned here and all seems to be fine, resistances check out, there are no shorts. The switch sits on a small board with a speed control knob. Since everything else checks out, I suspect this to be the issue but I am not sure. The board contains the folowing: Speed control knob, power switch, 2 resistors (one smaller 100k ohm one a little bigger 300k ohm), one small capacitor(unsure of rating), a BTB12-600B triac, and a 0.22uF rectangular capacitor. What to do next? I suspect that 0.22uF capacitor to be the culprit, but I am not sure...

Excellent information and very well done! I am working with a Kirby G4 vacuum motor that’s sparking and smoking. I did every test you demonstrated on the armature which is new from Kirby and it passed three test and new brushes also. The bearings are good as the rear bearing is new with the armature. The wiring and contacts all check out and the field winding passed both test. Everything went back together as was from pictures and notes. When I turned it on it was as if I had done nothing! Still sparks like a bright burst on the commutator at the brushes?? Do you have any suggestions? It is a very well made machine worth fixing. I’m planning to get a new motor for now unless I can fix it. I’m determined to find what is causing the problem and may end up with a spare motor or one to sell. Thanks for your work you’re the best.

@tmyersf4 Жыл бұрын

If it sparks then try cleaning the commutator with some contact cleaner and see if that has any effect. There might be carbon buildup between the copper segments preventing correct contact with the brushes.

Hey, I have a newer version of this with a controller put in before one of the stator windings for speed control. Armature and Stator passed all the tests you showed, however, Grinder won't spin, its just makes a humming noise. Any Ideas what the problem is?

@MrDIYer Жыл бұрын

Try turning the speed controller slowly either speed up or slow down, wiggle the knob, my take is it already has some play to it, if the grinder turns, you can lay the blame on the speed controller.

@RaumzeitRecords Жыл бұрын

@@MrDIYer It doesn’t turn, I redid everything, the commutators diagonal resistances don’t match up anymore, which is sad It worked before I changed the bearing, now it just hums. Me armature is to expensive though to be worth it
