MTT EP8 4 Cheap 3650 Motors Tested Surpass VS Gool RC

[@DJ.1001]

Surpass makes the majority of the brushless motors on the market today. Once you study their design and build features you will notice it on everything, even high end race motors. Fantom, reedy, rocket, hobbystar, reve d and many others. They are all oem by surpass hobby.

[@genemaster74]

i live in Australia, and do all my rc shopping on Aliexpress, their range in massive and better pricing. I'm into crawling and i only buy surpass motors, as ive never had an issue and this vid shows it. Cheers for your time m8 in doing this video, from a m8 downunder

[@LawrenceTimme]

Yes they are great value for money. 🙂

[@waukell]

One of the best examples of what I needed to see since I’ve only owned a couple traxxas ready to run brushed cars.

[@druscanam]

Thanks for the video test. On brand new motors I found that if they are a little noisy it's usually the bearing is a little stuck due possibly surface rust but most likely the adhesive resedue they use to glue on the permenate magnets during manufacturing. With all new motors I always spray a little brake or contact cleaner on each bearing run it for a few seconds then put a drop of oil on one end hold right side up run for 10 second the flip over and do the other side. Always seems to imidatly take the vibration out straight away and run much smoother/quieter and would probably help it achieve a tiny bit more rpm too 👍🏻

[@LawrenceTimme]

thanks for the tip, i might try that next time.

[@georgegonzalez9281]

Testing these motors under a load or actually installed in an appropriate vehicle will give you more realistic results as to the quality of the motor. The Surpass motors are not that good of quality but they work okay as long as you don't push them to the limit. Over gearing or running a prop that's too big will burn up these motors fairly quickly. I still buy them because they're cheap, but consider them disposable as I do.

[@LawrenceTimme]

So far the surpass platinum has been better than the hobbywing motor it replaced which was triple the price.

[@jonathantheunacceptable4259]

You need to put a load on the motors to have their amp draw to spike. They have no load other than the initial rotation of the rotor in this type of testing. You'll have to use a voltage meter and to have the motor in a vehicle, either have over sized tires on a bench or hold the vehicle while you throttle up. If it's a car put it on a loose surface and do a burn out. If it's a boat, hold it in place and have the prop force the water around it. Same idea with a plane but in the air obviously. You can hook up the voltmeter to measure the amps drawn from the motor or even the entire system depending where you connect to. Cheers

[@LawrenceTimme]

This A reading is the starting amp draw for the motor under no load as it says on the spec sheet.

[@tstricklin4808]

Agreed, load test would be better

[@tbrickrc7085]

depends on the wind if its a Y or D wind try adjusting the timing on the Y wind motors as to far advance it will heat up really fast

[@LawrenceTimme]

They are all d wind.

[@druscanam]

@@LawrenceTimme Yes usually all the higher Kv motor are Delta winds with the Y pattern winds mostly being used to create low kv motors since less winds are required to achieve low KV value Also because it's hard to make a motor have an exact KV ie an extra or even half a wind may drop the KV below what they where trying to achieve so instead they may use Y windings because using a cirtian amount of Y windings on a particular motor may achieve a specific KV they where hoping to achieve. Also all these motors are closed can so they timing would probably be set to zero as to allow equal rotation speeds for each direction of rotation.

[@PabloGonzalez-hv3td]

I have a few 2430 Surpass motors and they've been reliable but don't have anywhere near the advertised kV rating. Closer to half.

[@foxhoundra6444]

Based on this experiment, what is the most efficient and quiet motor to purchase?

[@rcmod642]

Please compare the rotor inside the motor to see if the explosion prevention thread is wrapped. The Queenhobby motor has no thread in the rotor, so I wonder what other products are like.

[@LawrenceTimme]

Hello, I don't think these smaller motors will have kevlar wrapped rotors like bigger motors do. As long as you don't go over the manufacturers recommended rpm and the motor is together it should not come apart.

[@kitchenbriks3685]

I'm curious to see how much those skinny leads your using are impacting the amp draw.

[@LawrenceTimme]

None at all. The motor tester is rated for 30A and none of these motors are anywhere near that.

Interesting video, thanks for posting. Out of interest, approx what effect on amps would occur with the motor under load in the car with wheels/tyres etc? I'm guessing that 5-8 amps you measured with no load will be multiplied many times over?

[@LawrenceTimme]

Yeah the load when the motors are running will be much much higher. It depends on the weight of the car, the weight of the drive line components and the gearing as well. Most of these motors are rated at 60-100A maximum, but on moderate gearing on 2s they'll be more like 30-60a.

[@gripihorche]

All three motor noises comes from bearings, the orange motor has the lowest quality ones. And maybe the red one is the only properly weight equilibrated from factory.

[@seavee2000]

Good video-the 4300KV motor sounded immediately like the bearings are shot. Much of the db is from bearing noise on all these motors. I have always thought GoolRC and Surpass were from the same factory, but definitely prefer Surpass stuff, it seems more solid.

[@Derpynewb]

Not neccisarily. Motor amp draw changes significantly under load. It just means the motor doesn't struggle to move it's own weight. I think higher KV motors use thinner motor windings which may make them lighter and easier to turn. Im not an electrician so I could be wrong.

The 3s 12.6v cannot be use also? Or the .6v and .8v can tolerate it? Thanks mate! Additional question If the 5900kv max rpm is 50,000rpm on 2s.

[@ericrichard5237]

@@ericrichard5237 Answer is no. It is more complicated. But for example: if you have 3650 800W 3000kv and 3650 800W 6000kv, torque is almost the same.

[@fabianrudzewski9027]

@@harynian what??? In your example, torque should be halved, if you don't push current to the moon. And if you do, you'd get way more power and probably smoke the motor. Which is only logical, since the 6000kv has less turns to get that KV, but a coil with less turns at the same current generates less fieldstrength, which directly translates to less torque. I once threw a 3000kv motor in place of a 2000kv one without changing anything else. Drew A LOT of current and still performed worse in acceleration. Had to gear it down considerably, to make use of the increased rpm.

[@harynian]

@@fabianrudzewski9027 Please, calm down. Question was simple: "Does lower kv make more torque", so answer is simple too: "no". Relating to my example: You have to know more about motor specification. 3650 800W 3000kv is rated for 16 V 50 A and 3650 800W 6000kv is rated for 8 V 100 A. Relating to the question: If you switch 6000 kv to the 3000 kv, with the same 8 V battery, you will get half of the torque. If you change motor to 3000 kv and battery to 16 V, you will get the same torque. You cant use 16 V for 6000 kv, because you will burn the motor. - a lot of people change motor to the higher kv to have more power and speed, because they use 2S battery and 2S is better for high kv motor - a lot of people have low kv motor and change 2S battery to 3-4S for more power and speed, because low kv motor needs more volts Brushless motor torque is calculated only from kv and current. Less kv = more torque, more current = more torque, but less kv = less current and you can check it in every motor specification. Summary: if you change motor 6000 kv 8 V 100 A to the 3000 kv 16 V 50 A, you will have half of the kv (more torque) and half of the current (less torque). Torque output remains the same in this situation. Relating to the coils: Yes, you are right. More coils = more torque, but only when current is unchanged. Unfortunately, more coils = coils are thinner = less current can flow. Tips: if you want to have more torque: - use as much volts as your motor can handle (look specification) - use motor with kv, which have max rated voltage as your battery - change motor to the bigger one Note: evey brushless motor is not empty inside, they are full of coils, no matter if they are thinn (many coils) or thick (few coils) and coils have their specified current resistance. You just cant build "much" stronger motor with the same size, you cant cheat the physics. The true way to have stronger motor is to buy bigger one. I hope it is clear enough now.

Goolrc motors as with a few other motor brands are made in the Surpass motor. Sharing alot of the same "casing" (I would say amateur although in this contex the meaning would be confusing 😂) as for the internals and design measurements I'm guessing they are made to manufacture specifications or perhaps use an old Surpass Hobby design. Eaither way yes, I would always just get the Surpass Hobby as I would assume they would have a little better quality when making motors for themselves then their competitors. If you want to try more surpass hobby motors , there is quite alot of different product ranges. For budget I would say their platinum line is a a good one with a few improvement over the classic line such as larger bearings for motor size, ribbed design for better cooling also the leads and plugs are better too, for example a kk series 2845 will use 3.5mm plugs whilst a platinum series will use 4mm plugs. Also rocket is their more premium brand making a few lines of sensored 2 pole (all 1/10 race motors are 2 pole) class leading 540 race motors, 4 pole 1/8 scale sensored race motors. As well as a bunch of sensorless car and boat motors too. Also surpass also make some budget blue can sensored 540 motors and 1/8 scale orange can sensored motors too.

@@LawrenceTimme I believe it depends allot how people use these motors. I’ve heard people complaining their esc burnt out after using a high KV motor with a low amp esc on a 1/8 scale monster truck on snow..

[@LawrenceTimme]

@@suubierex9396 not they have used them correctly on the forum most people use them to replace a brushed motor. You can see video of it which they stutter and don't work well at all.

[@camrowdrone6497]

Great video, really enjoyed watching this, been looking for a good high Kv motor👊🏻👍🏻

[@ethanboyer1287]

i bout one of those moters and my radio cant huke up

[@ValFPV]

the motor isn't what the radio is supposed to hook up to bro

[@R53.charlie]

Hi mate, just to say, you should check out racerstar, they’re the same rebranded motors like surpass hobby, I have 2 myself, one that’s the same as the 5900kv you used in this test, and a bigger 3660 can 3300kv 4s motor, the quality has been amazing on mine, and, even the 3660 motor was £16, and that’s rated at 4s! It’s a BEAST on 4s in my rustler 2wd, talk about pizza cutter tyres🤣

[@shepshepson]

What kind of Esc could it use?

[@R53.charlie]

@@shepshepson I’ve got a racerstar 120amp esc, it’s £35 on banggood

[@philthyco1]

That motor analyzer is nice!!!

[@michapawliszyn9609]

you start testing with different battery voltage!!

[@LawrenceTimme]

?

[@josephfast5887]

@@LawrenceTimme what he is saying..u didnt recharge your battery to test each motor. Your battery became a little variable in this experiment being that it differed with each motor.

[@josephfast5887]

@@LawrenceTimme also all motors come different kv s than advertised. U can do that test with ten of the same brand and kv motors u will get different results on all. All motors with shafts amd bearings need breaking in. Afyer a few battery packs the kv will go up pretty close to what its supppse to be

[@LawrenceTimme]

@@josephfast5887 yes they come with different kvs from new, but no they don't get broken in. A brushless motor doesn't break in like a brushed motor.

[@LawrenceTimme]

@@josephfast5887 yes the battery is not charged between runs because the charger is not accurate enough. Also this is very low current and power so it doesn't really make a difference. The kV is the rpm divided by the voltage, so even if the voltage dropped a bit, the rpm will drop as well, so its not really effecting the result

[@ethanboyer1287]

i seen sencored on the box

[@LawrenceTimme]

All these motors are sensorless.

[@AphexTwinII]

I like how he calls it GeeOolRC instead of GoolRC.

[@rcbreakdown3066]

It makes perfect sense, but only if you know how an electric motor works.

[@morta46]

Muy buen aporte, buen video si señor¡

[@gamebosan5965]

Good testing. Thanks

[@MarkJohnMorris]

Good information on motors, although im after 3s motors for an Arrma Big Rock. Thank you for the info though! Suprass much better. Can I just say though that the noise levels were pretty stable at 81db, but as soon as you started talking it goes upto 85/87. When you stip it goes down to 81db. So motor is 81db not 87db. Otherwise awesome stuff ❤

[@LawrenceTimme]

I have some other videos of bigger motors too. Not sure which would be best for your car though.

[@MarkJohnMorris]

@LawrenceTimme Ive found out my stock motor is fine and its the ESC that has failed me, causing stuttering and cut-off even at walking speed (car wouldnt go more than 4mph). But i have subbed and will watch more of your stuff, love info so brilliant channel 😉

[@caliboyzmountainbikeTV]

Can i used this in mn model rc?

[@LawrenceTimme]

What is mn?

[@jeffwarren9791]

The truth of the matter is that they’re all made in the same damn factories

china has a lot of factories

[@kitchenbriks3685]

Goolrc motors are ok to use but never ever use a goolrc esc!

[@LawrenceTimme]

This motor I got was terrible, they probably are very hit and miss due to bad quality control so I wouldn't recommend them.

why some words the "T" is pronounced and other words the t is silent??? there is a "T" in the word M-O-T-O_R correct? or he adds letters to a name goolrc is pronounced geecool rc???? where did the e and c come from? beda? i think he is trying to say better could be wrong

There all made in the same factory just branded different

[@LawrenceTimme]

This is sometimes the case, but there will also be multiple factories making the same thing. These are made in China so there will be many copies of the same thing made in different factories to the same design.
