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

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 👍🏻

Thank you for this information, that surpass motor 6900kv is impresive for the cheapo price. Not getting hot and low amp draw. I buy one. Thanks

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.

I have a GoolRC brushless motor like the orange one but slightly more kv and have ran it on 3s and it worked fine, it just got a little hot.

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.

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.

Hey.. I like your video.. I'm consern about the battery. Can I used just 12v motor battery to connect on esc?

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

Agreed, load test would be better

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.

Fabulous video, Lawence! So, in summary, can I say with same size, KV, the motor gives lowest current on the tester at full throttle has the most efficiency and thus the best one? I just bought the SurpassHobby 3650 3900KV and test it using the same tester you use, and I get 5A current @100%... compared to my other 13.5T motor which gets only 1.5A....shocked.

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.

@@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.

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. I use quite a number of GoolRC brushed ESC and they have been good,robust and able to take some abuse, thank you for posting,very informative.

Thanks for showing this. I have the 4300 and the 5900 motors and your analysis is pretty spot on. I think that 5900 is also available from KingVal which I have had good luck with so far in 2 of my cars. Ballin' on a budget!

The length. The numbers are the diameter 36mm and the length. 50mm, 60mm, 70mm.

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.

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.

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.

the motor is only pulling less than 10a but on the manual and the website they are rated as 60a 50a etc. what is this about?

I think , those are the peak currents , when you're driving the rc car.. accelerating full throttle , break etc that's when the current is the highest

@@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

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.
