    Great video!! They used to sell a gear puller. It would attach to the shaft underneath the pinion and a screw on top that would tighten down on the top of the shaft same diameter as the shaft. When tightened would pull the pinion off from the bottom. Hard to explain!! But worked good. Lol. I raced b4 brushless came out. We had miniature lathe’s. To cut the commutator with a diamond bit. I still have mine. They also sold a lot of different brushes and spring options back then. Yes I’m old LOL 😂

      There are several options for pinion gear pullers out there. The problem is I've never really found one that was strong enough to rip a stuck pinion off of a shaft in the sizes of gears that we typically use these days. They usually just bend

    The biggest advantages of brushed motors next to being cheap is that they have higher starting torque and run smoother at lower speeds, while brushless motors tend to cog. You need a sensored brushless motor to mitigate that and those are quite expensive. For something that is supposed to go slow like a crawler or truck, brushed is still a very good option.

    • @DoRC
      @DoRC  Місяць тому +2

      True though sensored brushless systems are a lot cheaper than they used to be.

    If Allen/ hex screw won't come out or is rounded, use a torx bit same size and gently hammer/ tap in. The percussion of hitting it in helps break a stubborn screw and torx bit will grab into worn hex/Allen hole. Great for grub screws and no drilling / cutting needed. Replace worn screw with new one once out 👍

    Another major reason brushless motors are far more powerful then a same sized brushed is because rotational mass of the rotor in bushless is far less freeing up much more power. Brushed motors have the mass of the windings and a largerer diameter rotor causing more rotaional mass to accelerate

    The bread trick was genious! Also on the sensored motor you could try checking if there is any part number on these 3 black components on the pcb (the magnetic sensors) to replace them because they are dirt cheap and also there are not any other complicated components on the motors' pcb to get bad so, it is most likely to be the sonsors or just some connectrions from the pcb to the pinout.

  • @barbedwirerat661
    @barbedwirerat661 Місяць тому

    Great tutorial, nice techniques. Do you usually replace your problem motors with new ones, and then just set the old ones aside as future repair projects? There are some brushless motors that have an endbell/plate that isn't removable...or at least does not have any fasteners that hold them on...I don't know if it is just press fit or if there is an adhesive involved. Anyway, do you have any thought on working on those motors for getting bearings in and out? I suppose if that plate is on the shaft end there is probably room to knock the old bearing out from the outside (though if the bearing comes apart the outer race could get jammed in the bore). I guess perhaps these are the cheaper motors so not as big a loss if they can't be fixed.

    • @DoRC
      @DoRC  Місяць тому +1

      I've got a pretty decent reserve of electronics that I can dig into if I need to so broken motors tend to pile up until I get a chance to sit down and fix all of them.
      There are some brushless motors that don't have a back end bell and in that case you're pretty much just having to reach down inside them to replace the rear bearing. It can be kind of a pain. Generally speaking with the bread trick the bearing won't come apart so it should be removable that way though getting the bread down there is going to be a little more challenging.

Thinking some of the windings may be burnt or damaged, but I believe the rotor is nearly identical size to thr Spektrums, so I was thinking of trying it, but haven't yet.

      The freezer thing isn't quite as effective as some people think it is.

The temperature differential just isn't really enough to make much difference. You really need significant Sub-Zero temperature is in order to shrink it enough to really affect the fit much.

    • @DoRC
      @DoRC  Місяць тому +1

      For a given size and for amount of power supplied a brushless motor will pretty much always be more powerful. There are two main reasons for that. The first one is that they use neodymium magnets which are more powerful and the other one is that there is no power loss due to The making and breaking of contacts at the brushes themselves. That's not to say that a brush motor can't be powerful because they can be and some are even made with neodymium magnets but brushless inherently is able to use the available power more efficiently.

    • @captainchaos3053
      @captainchaos3053 Місяць тому +1

      @DoRC I see your point and perhaps my experience of motors is just a bit different than yours but I have found that in most instances even though they turn to very high rpms with ease a brushless motor produces less torque for a given wattage. I think they are definitely the way forward for many applications. Maybe newer examples are making more power but my experience is that most rc manufacturers are using high rpm motors with significant gear considerations to achieve the correct power required and avoid the cogging that often befalls them at start up.

    • @DoRC
      @DoRC  Місяць тому

      @captainchaos3053 hmm maybe. It is also possible though that brushless motors run at higher RPM simply because they can. Brushed motors do have RPM limitations based on the centrifugal force that the mindings can handle and the surface speed that the brushes themselves can handle.

    • @captainchaos3053
      @captainchaos3053 Місяць тому +1

      @DoRC Yeah that is also true. I believe the lack of brushes and therefore frictional heat also helps. In general they can tolerate high current better as there is no arcing which in turn allows for higher voltages and currents than ever thought possible in the hobby. 20years ago a 60v battery and over 200A just would of been so impractical but now it's quite normal. Perhaps that's why people think brushless is more powerful.
