Repairing the 8000w Tommebike Icon part 1

I blew the qs273 8000w hub motor, on the Tommebike Icon but hopefully I can get it back on the road soon This is part 1 of the repair on the Tommebike Icon.

Add cooling oil to the motor, this way not only the electromagnets get hot, the heat is distributed evenly in the motor body. However, you should wrap the heatsink cooling immediately around the motor, this makes it easier to throw the heat inside out. In this way, I can run my 2000 watt motor with 6000 watts of power, it was very useful.

[@E-bikeguy]

Yo what’s good I have a rare request. When you take the motor out to swap wheels, can you measure the diameter of the motor? I have this wild idea of fitting just a solid 14” or 16” tire on the motor itself as an experiment. Crazy idea right? The dimensions of the QS273 online appears that it could work. Then again maybe not. But that’s the great part about diy is we can push the envelope far ahead of what mass production bike builders are doing. Keep us posted on the repair! And ya this hobby is NOT cheap! I’ve also been looking into a batch of P45b Molicel as well as waiting to see when the P50 will be released. Because then we would have the option to build a smaller sized battery, say with 25-30% fewer cells but make the same power as the mega range battery.

[@E-bikeguy]

Oh heck yeah I'll do a measure for you

[@user619tlsdca5]

Good to see you EBH after hearing about floods in FL. My first ebike from 4 years ago , one of the gears is broken and now no good. It had 41k miles and I used it many times going up 6 hills every day. Only 600$ 4 years back and I converted it to be a dual motor so its running still until I replace that rear motor with another rear I have. Was a great first ebike buy for cheap of converting to a dual motor, learned alot off this first DIY Build with 4 more others I bought and upgraded later on. The ebike you have here is hell of an ebike! Love them big tires as it is best to use them fatter ones for speeds over 35mph. The tire pressure on standard 2 inch wide tires goes thru alot of impacting between road and faster mph, they usually get deflated more often. I just ordered a regular Trike Bike to convert into 2ooo watt ebike, had to make sure the front forks haf shocks for its 1 extreme need for ebikes over 500 watts from snapping or breaking.

[@tacticooldennis]

I thought i blew up my motor a few weeks ago with a sabvoton controller. it did something similar with what felt like hard vibration with the power going out. I ordered another motor and controller, but after testing it with a ebike tester, determined it was the controller itself. the one good thing about these ebikes is they are simple machines and many times you can just replace wires or capacitors and get it back running easily. Sure beats a piston going through a cylinder.

[@imho7250]

I hope your supplier sends you a stator with temperature sensors because if you had that and had them selected in settings your motor wouldn’t be fried by a wrong tune or turn and burn settings. AN is the magnet arrangement. AN 0 for the large diameter surface mounted motors, AN 6 for the OEM Surron, AN 14-16 for V-type embedded magnets. LM is the waveform. 22 is default but I find 16 runs smoothest. You can set this in your living room or any quiet place. As per the Fardriver manual, just decrease 22, 18, 16, 14, 12 until it feels/sounds smoothest. Always set the HIGHEST LM value that gives smooth operation. So if 18->16 felt good, and 16->14 not sure, couldn’t tell, set it back to 16. The test is just accelerate from a stop a few feet. Don’t need to go far or fast. You will hear/feel if it’s better or worse. The temperature sensor is like a BMS, worth every penny. My motor doesn’t have one because it’s a 💩 motor with no optional temperature sensor but if I ever buy a QS motor, it will definitely have a pair of KTY83-122 sensors in it. It would have paid for itself 10x the first overtemp it saved you from. You have a 4kw motor, and a 12kw controller with peak power of 43kw. So temperature sensor is pretty important.

[@E-bikeguy]

Thank you man you is a fardriver God!!!!

[@E-bikeguy]

@@frazzx6 I agree 👍

[@mA-ug5ts]

would a smaller fardriver be a sweet spot or I misunderstood?

[@imho7250]

@@frazzx6 ,yes, the Fardriver manual isn’t very clear on how you would know which hub motors should be AN:0 and which should be AN:2-4. The KO Moto manual gives a better explanation of the settings for Fardriver controllers since it is basically a Fardriver controller. Yes, its strange they even make a 273 40H without temperature sensors, since every real controller has motor over temperature protection. But the cheap generic controllers don’t which is why many hub motors don’t have temperature sensors. They do make cheap 4000w controllers so I guess they offer a way to save money and not get the sensors.

[@imho7250]

@@mA-ug5ts , the Fardriver 721200 can be set to behave responsibly with a 4kw motor, but it comes with default settings for a typical 12kw motor. The thing to understand about a motor’s rated power is there are so many variables that affect it. A 273 40H motor is considered 4000w continuous power but even that depends on if you are in Siberia or Florida temperatures, and going uphill or down. Most OEM controllers will deliver 50%-100% of rated power, so a 4000w controller would give 6000w-8000w peak power for acceleration and then the rpm control pulls that down below 4000w. So it’s very hard to burn a motor. Manufacturers do this because they have a warranty. Fardriver controllers can sent 300%-400% of rated power. So a 72530 (330a DC) using 72v can peak at 24kw and that is more than enough for a 273 40H, and still must be set to pull current down to the maximum continuous watts the motor can tolerate. And since it has the capacity the burn the motor quickly, they have motor overtemp protection but that only works correctly if you use a motor with temperature sensor. When you connect a 43kw peak controller to a 4kw motor, it doesn’t spontaneously ignite, but if you use wrong settings with no over temperature protection, its very easy to burn the motor. The motor is basically copper wire with an enamel coating that insulates it from the other wire and the stator. When it gets too hot, that varnish melts, and the motor is burned. You can send as many amps to a motor as you want, as long as the windings don’t overheat. This means every amp value above maximum continuous has a time limit that gets shorter and shorter the more amps you send. This is why Fardriver has a BOOST feature, for those who want to send 3x-10x power to their motor, but for only 5-120 seconds, followed by a 5-120 second cooldown. BOOST does not make the controller more powerful, it allows you to use an over powered controller on a smaller motor safely. I use it on my 72360 with a 2kw motor. If you set a 721200 to TURN AND BURN with a 4kw motor, and you do not have any self control, and don’t have a temperature sensor to monitor, that motor will be burned for sure. Many people have done it. The cause of this motor failure is still unknown. But if he had TURN AND BURN settings (which is the only way he rolls lol) and in his testing he learned he can give it full beans for 20 seconds before the magic smoke comes out, and then sets LM too low, causing the motor to run very inefficiently, turning more of the amps into heat than into torque, the motor would burn is less than 20 seconds.

Maybe the phase wire insulation just melted and your phase wires are just shorted. If so, get some 130c rated rubber electrical tape from home depot, re-insulate and you should be good! hoping for the best, can't wait to see the inside of this 273!

[@zentechnician]

Take your measurements at the windings. Completely remove the phase wires. I've done this myself so your motor is probably fine. You just need to replace the phase wires. The bike dropped because your phases were shorted together outside the motor windings. That will absolutely stop you real hard. The Fardriver doesbt do sensorless mode as far as I know. So you needed the phase wires which then melted the hall wires so that would stop you dead too. Don't panic. You're probably fine. Smell the motor. Burnt windings is a very distinct smell. You cannot miss it. The phases are all connected together at all times. That beep doesn't mean shit sir. You test the resistance between phases not continuity. The windings all connect together inside the motor. That's how the whole thing works dude.. Alternating signal with a shared neutral.. You should know this. Just replace your wires. Measure ohm's between each phase. They should all be the same. It will be a very low reading. Your wires just melted , that's a big ass motor, it can take a lot of abuse. Open it up I bet it isn't even black in there. You would smell those windings.

[@E-bikeguy]

Dang ok I'll do that in part 2 I just ordered a stator I'll probably sell it then

[@zentechnician]

@@E-bikeguy I bet you are fine. The windings I that motor are single core and probably quite beefy. Solid wire has about 25% more ampacity than stranded wire. So your phase wires would have to be that much bigger than the wire in your motor just to match it. What did you have field weakening set at, if you passed the point of hysteresis all you are doing is creating heat. People tend to be too generous with the FW. Now your current carrying ability of your wire cannot exceed what can be pushed through its smallest section of wire. A bottleneck. Your throw power at it and if it doesn't make it to the motor to be used then shit is going to get melty. Heat is the enemy here. So I'm guessing you rewire those phase and hall wires and you are back in business. Seriously. Take a bolt out if the side cover and give that hub a sniff. Burnt laquer/enamel is loud. If the windings are burnt I would be very surprised. Even then though as long as there aren't breaks in the coils or severe meltage you can still use the existing wire . They sell spray for the windings. Ive seen people spraying over top of their windings and that is not how you do it. You have to unwind the wires and spray them unwound or you aren't achieving anything. The insulation on the wire is only as good as the thinnest spot. If you spray the winding with them wound you aren't getting coverage in the exact place that you want the most insulation, right where the wires are touching each other. You don't want them shirting across themselves or the next phase since that kills the magnetic fields that are inducing power. Your phase wires are probably wound in a wye configuration. Google that and look at the how it's wired. All 3 phases are tied together at the end. That is the your neutral point. They are always shorted. Electricity is always a loop. It wants to go back from wence it came. Neutral is not a ground, it is 180° opposite whichever phase is currently charged. Some people think it's AC power but it is not. It would be a BLAC motor instead of a BLDC motor if that were true. I did the same shit to my motor with a Fardriver. Phase wires had been pieced together after the hub motor chewed up my dropouts and spit them out. I was using some wire of questionable quality and when I put the amps to them they did exactly this. The fact that your wires melted indicates your windings are still conducting sufficient power to liquify your insulation. You should be fine. You should plan on replacing all your halls I'm guessing. I would just replace all the external wires. Have fun fishing those wires through there. That's always special. You can use a Ethernet cable for your halls etc, there are 4 pairs of 26 or 28 AWG single strand copper wires in an Ethernet cable. It's real tiny and it's rigid so it's easier to push through an axle. Use real copper wire for your phases, avoid CCA at all costs. Copper clad aluminum is horrible stuff. The motor probably came with CCA. Mine did too so you needed to replace it anyway. That crazy controller and aluminum wire and a street race. Yep. That oughta do it. Crossing fingers youbdibt need a motor. I think you will be golden after a couple of hours of rewiring and cursing.

[@zentechnician]

@@E-bikeguy If you can't turn the wheel at all then all 3 phases are shorted. If it cogging and moving one magnet at a time then 2 of the phases are shorted to each other. If you ever need to know your magnet count in your motor you just touch 2 phase wires together and turn the wheel and count until you are back to where you started...use the valve stem as your start stop point. Put it at whatever o'clock and rotate.

[@E-bikeguy]

@zentechnician ok definitely have resistance

[@zentechnician]

@@E-bikeguy get those melty phases out of there. Just cut them off a prepare yourself for an evening of fishing wires. I'm sure the axle in that motor is quite large. What size were the existing phase wires? Have someone jiggle the wires while you spin the wheel and see if it's intermittent. My phase wires came together to form Voltron, if Voltron were a gooey bundle of non connectivuty goodness.

What was the problematic pid tune on your fardriver? I'd like to avoid the combination in the future uf possible to be safe. Thanks man.

[@imho7250]

As stated in the video, he believes it was when he set LM too low. LM is the waveform and must match the motor. If you know anything about tuning old cars, LM is similar to ignition timing. Setting it retarded is safe but doesn’t make the motor run its best. As you slowly advance the timing, based on the fuel octane, the motor runs better and better. But at a certain point, if advanced too much, the combustion actually tries to push the engine backwards and it makes less power and extremely high cylinder pressure. Same with LM. Default is 22. It normally runs ok, safe, but not its best. As you “advance” it to 20…18….16… it gets better, smoother, quieter, cooler. But if you keep going 14…12…10… it starts to run inefficiently. The power going into the motor starts making more heat than torque. Thats why the Fardriver manual says use the highest setting that gives a noticeable improvement in the motor jitter. For me it’s 16. For all QS273 I helped tune its 16. But its highly dependent on the motor magnets, which determines the AN value. The final analogy is, if you take 3 different motors with different magnet arrangements, and connect them to an oscilloscope, and and spin the motor to create energy, each motor will have a different wave form. To make each motor run smoothly, it must use the same waveform from the controller to give smoothest most efficient operation. For most hub motors it seems LM 16 is the sweet spot. KO Moto, which is a Fardriver with some hardware changes, actually doesn’t allow you to change LM with the new app. And for the PC app, they recommend not changing it. But perhaps they set it at 18 or 16 default instead of 22 and lock it there.

Hi that’s to bad but it’s a learning experience but you can learn how to rewind the stator and make it work at hi amp there is a KZbin on ingland and in colombia that they have drifrent combination of rewinding got to look it up can put better wires.

[@jc8417]

Just got my qs273, sometimes when I accelerate hard it makes a knocking sounds/jolts then controller shuts off, any ideas?

[@ianmangham4570]

Check phase wires

[@powchainsamaniego6744]

Next time update the wires

[@troop8829]

Those 3 fase wires are quite thinner than it should be i think. I’ve also been thinking this for many months about my own bike and I have been guessing what size yours are i seen em now.

[@E-bikeguy]

I just took the stator out and it melted

Hey do you have any experience with the vruzend diy battery kits? Seems really cool not having to use a spot welder to build a custom battery. I was wondering if you could build a battery with molicel p45b's i need a triangle 72v 80a, how much would you want for something like this? Thank you 🙏

[@BGIGAMERS]

Can you help me find somewhere in the USA or china that sells good electric bikes. I'm looking for prices around $600-$800US, 750 motor 15ah battery.

[@hardyharr1361]

Meelod has a few bikes around that price range. I don’t remember the Ah though.

[@LarryRichelli]

Are Tommebikes available anywhere. I can't seem to find that brand anywhere. Is it a bike brand or something you came up with?

[@E-bikeguy]

It's something I created
