YOU Can Fix Your RC Motor! Here's How!

[@smoothrc28]

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 😂

[@DoRC]

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]

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

[@clockworkvanhellsing372]

Sensorless smooth field oriented control exists. The odrive boards and clones support it down to at least ~20 rpm. You can't convince me that this doesn't involve witchcraft, but it is possible.

[@ZapTeam]

Depending on the kv of your brushless motor you can get more low speed torque

[@razorblade7108]

@@ZapTeam Even a low kV brushless motor has low starting torque, which can only be mitigated with sensors and intelligent ESCs. It takes one full rotation until a normal brushless motor reaches it's full torque, because the ESC doesn't have proper feedback from the motor windings beforehand and randomly fires on the three phases. A good 5-pole brushed motor with lots of turns still beats a sensored brushless motor with low kV in starting torque and low speed control for less than half the price. The low kV sensored brushless systems make the most sense for rock racers and rock bouncers which need to go both slow and fast. But for pure crawlers they are kind of a waste of money.

@@DoRC it's a Spectrum Firma 2050 from a Kraton. It's got those ridiculously small stiff wires with the bullet connectors that don't fit anything but a Spectrum ESC. If I cut the bullets from the Motor then the wires are going to be too small to reach anything.

[@DoRC]

@@kylarstern7627 those wires are the actual windings from the motor. You can technically solder onto them but if you don't solder onto the part that already has solder on it you're going to have to get through the enamel coating on the wire first and it can be problematic.

[@DoRC]

Yeah and they probably didn't have high speed specific bearings in them to begin with. I'm not going to lie I've thrown regular bearings in motors in the past and haven't really had any problems with it I just don't like to recommend things that are outside of the specifications of the parts.

[@jalee6587]

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

How do you know if your windings are burnt,or wiring is no good? I have a couple motors I bought and only ran 4-5 times and they quit. I can't see anything wrong with wiring or windings. I ordered good motor bearings and motor turns slow,I thought maybe I lost a spacer,but I have them on both sides and everything fits tight shaft spins freely by hand. I don't get it! And its a $120.00 Castle that I only ran a few times. It really sucks that it quit working so fast. Take it apart and everything looks brand new.

[@DoRC]

Usually burned windings are very obvious because they will absolutely reek. You can test to see if there are open circuits between the windings by using an ohmmeter and checking between each of the three wires. They all should have a similar resistance and it should be pretty low resistance without being open circuit.

When installing bearings if you put the bearings in your freezer as well they should just drop in place.

[@DoRC]

The freezer thing isn't quite as effective as some people think it is. Going from room temperature to freezing is only going to give you about 0.0002" or 2/10 of of a thou on a 20 mm diameter bearing. 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]

Is technically possible to repair windings but unfortunately it's generally not really economical from a timestand point. You're pretty much going to be cutting the old windings out and threading new windings in which is not going to be fun.

[@NerfCraft]

@DoRC I've got a couple of stock Kraton 6s motors with bad rotors (broken magnets) and I think it's a Poisedon motor or something like that, just stutters when I try to run it on a known good esc, even without load. 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. Ideally I'd like to get the Poseidon working again just for fun, cause it was actually bigteedos motor that he ran in his 100mph erevo.

I would disagree about brushless bcing more powerful and i have tons of rebuilt brushed motors i havd one that is 27 years old and still runs perfectly up to 32000rpm

[@DoRC]

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]

@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]

@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]

@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.

I responded to your other comment. My email address is available in the about section of the channel. You have to look at it on desktop though.

[@normcleod360]

I've done 3 out of 4 of those. Didn't know about the bread, DOH. 😏

[@DoRC]

Nice! The bread trick is fun :-)

[@Boogie_the_cat]

The trash can upgrade is the most long lasting upgrade for a brushed motor, your new brushless motor will last much longer. And the trash can keeps the brushed motor from stinking up the place.

I have a castle 1717 motor with a bad rotor….castle doesn’t offer a replacement rotor for this size motor…(figures 😢) I did email them and they offered a core return price for a new motor $130…..not terrible I suppose …just rubs me wrong cause I could fix it myself if I had the parts…

[@DoRC]

Yeah I'm not really sure why they offer replacement rotors for some motors but not others. It seems strange though I'm sure they have their reasons.

[@Macgyver46]

I have spektrum 1900kv motor, when vertical the drive shaft can move up and down a little and hit bottom. Would that be a bearing? Bench tests sound fine.

[@DoRC]

There's always going to be a little bit of axial play like that. As long as it's running fine it's not a problem

[@Macgyver46]

​@DoRC Thanks. Oh they also sell pinion gear pullers on Amazon, had to use one last year because the motor plate was in the way of the grub screw.

[@DoRC]

@@Macgyver46 Yeah there are a couple that you can buy though I have found that they tend to not work very well. That's just my experience though

[@buckrogers8858]

Lol the bread trick also works for throw out bearings for real cars

[@DoRC]

Yep. I learned from an old-timer Volkswagen mechanic when I first started turning wrenches 25 years ago :-)

Radio shack?

Sorry not sure what you're asking here.

[@bb.ben.g]

​@@DoRC haha no sorry I wasn't asking anything. I noticed the bottle you used of contact cleaner was from RadioShack!

[@DoRC]

@@bb.ben.g ah. Yep an oldie but a goodie:)

[@davidbegeotsr4025]

That thing you're calling the rotor is called a armature

[@DoRC]

In this case the armature is technically the stator. The armature is the part of the motor that the electric current goes through. The magnets are on the rotor in this particular setup so it wouldn't be considered the armature

[@Murphys_Law9]

what about one that broke open

[@DoRC]

What do you mean?

[@PigglyWigglyDeluxe]

11:52 if you ask Joe at Castle he’ll tell you they repair sensor boards. However, if you ask Linda, she’ll tell you Joe is full of shit and needs to stop saying that. Ask me how I know. 😂😂😂

[@DoRC]

Lol. I'll have to find out.

[@isaackshirley4695]

What's wrong with the motor when it is harder to spin it and the bearings is good

[@DoRC]

When you say harder to spin what do you mean? Also how are you verifying the bearings are good?

[@Matty_mccfly]

Bread has been used in the auto world for a long time.

[@DoRC]

Yup. Learn it from an old school Volkswagen mechanic many years ago.

[@thomaswalton9089]

Funny thing is i used my sister in laws tooth brush last night to clean my car cause i couldnt find an old one lmao

My girlfriend always asks me why her toothbrush tastes like brake cleaner. Little she knows. 🙈

[@DoRC]

Yeah it can definitely leave a little bit of an aftertaste.

[@timmy4539]

I have a way better and way easier way to fix a motor !! If one of mine goes bad i'm just going to send it to you to fix !! Lol

Sounds good :-)

I coukd fix that sensor. A multimeter in diode mode. Castle motors cost like 100 beans plus tax in nova scotia. That's a horrible iron brother. You shoukd refer people to basic electronics repair instead of fumbling over a lesson. No offense, great video. Get a ksger stm32 oled t12 station. Then you don't have to worry about waiting to change tips. The built in ceramic heaters in low end irons are a pain. I fix electronics for friends and repair game consoles. Microsoldering is a hobby. I use an lcr meter too.

[@DoRC]

Yeah I could also fix the sensor. The video was aimed more at people who probably wouldn't have the skills or inclination to do so. I wouldn't say the 888 is a horrible iron. It's certainly not high-end but it will do everything the vast majority of people in this hobby need to do. I've been using that iron for both RC and electronics repair for probably 10 years now and it's never let me down. The only issue is is not quite powerful enough for some of the largest connectors that are currently being used.

[@jstro-hobbytech]

@DoRC cool. Sorry if i came off like a know it all. A ksger t12 stm32 oled station from ali will last you forever man. I paid 140cad years ago but they go on sale for 40usd all the time man. I upgraded the handle but didn't need too. I have a jbc station now and would be up for a trade for an old rc if ya wanted. I'd include tons of extra cartridge tips, leds of every type and shape along with some other stuff for repair and new rc parts. It's up to you, I have tens of thousands of leds hahaha. I have a new 2 channel spectrum transmitter as well that I forgot to send back with an axial I bought and returned. I'd even throw in a multimeter if ya wanted a new one. I send electronics learning kits to random people for free but I stopped doing it recently because I'm saving for a road trip down to Utah and some other places. I want to go to some rc comps (as a spectator) along with some swap meets. Even with the exchange rate, rc is a super expensive hobby here compared to the us. I'm building an rc park on my property at some point and might have an open house where I give away a bunch of rcs to get the hobby going around here. Im 45 and retired haha. I have a ton of hobbies and I'm thinking about getting a second engineering degree this fall to pass the time haha.

[@DoRC]

@jstro-hobbytech I appreciate the offer but I actually have a generic jlb station sitting in a box waiting to be setup. The QS8s I solder need more jam than the 888 can do so this one is 250w:)

[@shawnfreeman7802]

@@jstro-hobbytech hey,what does it take to be your friend? I sure would be eager to learn from you!

[@MyKonaRC]

Im screwed when I cant buy a new rotor. Most motor bearings are easy to find, rotors on the other hand are not as simple. Buy a new motor instead.😶

[@DoRC]

Yeah both Castle and hobbywing offer some options but unfortunately they are pretty limited and seem to be fairly random as to what you can and can't get.

[@meanus01]

Seems like castle motor are crap!

[@DoRC]

In my experience they don't really fail any more often than any other motors. It just so happened that the pile of motors I currently have were all castles :-)

[@torpedoLaw]

I got the first comment, how about that?

Nice!
