What a great project. I love how your earlier videos are now making it easier for me to follow your block diagram with a a minimum of explanation. Normally I'd think - why an inverting Schmidt Trigger? But now I see oh the P channels can be driven with it and no further explanation. Thanks for such great content.

@terminashunator 6 років тому
As an avid eBike cyclist, I really enjoyed your video! Just so you know, you can remove the disc from your old wheel and use it with the eBike hub if your alignment is correct. The six hex screws on the side of the motor should align with the holes on the disc rotor from your stock bike wheel. This project is really interesting to me, since I play with RC rock crawlers (that use brushless sensored motors) and eBikes (also use sensored motor). Keep up the great work!

Again you deliver a video about something I was researching about. Great job! I'll be working on this too in some months hopefully.
@wi_zeus6798 6 років тому
Should you ever want to use the full potential of such a motor, I'd definitely recommend torque-arms! I built something similar with a VESC and the steel of my bike was deformed rather drastically (after about one month of driving around). Please add regenerative braking too, it would be extremely interesting to see that implemented. Since I'm already asking, some current shunts for power measurements would be a nice touch too ;)
@LoganT547 6 років тому
Manuauto another idea is recycle a Fisher and Paykel washer motor.
@KerbalLauncher 6 років тому
It already has regenerative braking, if the motor is running at say 20% max speed and you feed 10% duty cycle, current will backfeed into the supply because of the inductance of the motor windings.

Well, I will probably not use my own ESC for the second part of the video series. But I think a test run with it will follow.

Hi Andrei!, from my own project, those hub motors usually consume about 16-20Amps of current at initial start, then when the speed rises, it drops to around 10Amps

@Elisworkshop 6 років тому
Hi great Scott! This was a great video, you are a genius! There is one thing I really want to point out to you for your own good. I have made many ebikes, I purchased a hub motor for the front just like you. When I put it on my bike the hub motor the second I put power to it on the ground the mounting taps broke on the forks. I don’t know what it is but the magnesium alloy is very brittle to the motors torque. I really hope you see this because I have broken 3 forks like that and had to get steel ones. I think it’s a huge safety hazard and don’t want it to happen to you!!!

@thecubinggamer2191 6 років тому
Great video. I built a similar ebike but with a rear hub motor. I think with the front hub motors you have to be carful to make sure that the front forks can take the force. I’m just using stock ESC for mine, I’m interested to how yours will turn out.

@LazerLord10 6 років тому
I'm currently working on an electric scooter project, and the ESC (and motor) I have are both sensorless. It kinda works, but fixing the problem seems to involve buying an ESC that's far too expensive. Any recommendations?
@jakegarrett8109 6 років тому
I've seen a $20 ESC power a pretty big brushless motor (actually it was a full size car alternator being used as a brushless motor, so pretty big). As long as its not over 500 watt, I think it shouldn't cost too much, but it also depends on the voltage. 12v (3s Lipo) is usually pretty cheap, but getting into 48v or something like this video might be expensive, so it kind of depends on the motor you want to run.

@R3MIXMODZ 6 років тому
A couple years ago, my parents had a motorized bike that the base was a cooler so it was a motorized cooler to hold drinks and stiff. It ended up breaking(which was probably a simple fix) and they sold it at a sale for $50. Sadly I wish we still had it because I love to work on that stuff and I would have had a great time with it.

@anlpereira 6 років тому
Hi Scott, another thing I would like to see. Could you make some deep approach showing the relationship between number of poles of stator and rotor. Where to place the magnets and when to commute phases. I don't see, for example, a motor with same number of poles in stator and rotor. Thanks a million
@KerbalLauncher 6 років тому
Really cool video! I have one question though, I noticed you did not use any dead-time control, how did you manage avoiding shoot-through? Since International Rectifier MOSFETs have pretty bad gate charge characteristics.
@lennox1558 6 років тому
At first I read '' how to make your own censored esc'' 😂😂 But as always great video!
@ShaneMatthews27 6 років тому
BE CAREFUL!! that front fork looks like an aluminum one to me. You should NEVER use a hub motor with aluminum forks. I learned this the hard way. My fork failed and caused me to have a severe accident that landed me in the hospital for two days, suffering a concussion, severe abrasions to my face and shoulder, as well as a lacerated liver. On my new bike I have used a steel fork and welded on reinforcements on the front and back to make darn sure that it does not fail again. These things are very dangerous when not used correctly, as I learned.
@omprakashmaurya611 5 років тому
Thanks for the tip!
@silicongarden 4 роки тому
If using aluminum forks then you can always use a torque arm to absorb the load.
@DigBipper188 4 роки тому
It depends massively on the power of the motor as well as how much metal is in the dropout area. I would highly advise against going with motors with a power output greater than 500 watts if you have an Al fork unless you have the ability to fit some decent quality torque arms to the bile to prevent fatigue. Although even with a 250w geared motor I would ensure you use a torque arm wherever possible. Especially if you have thin Alu dropouts... My bike has done over 6000 miles since I went with a BLDC kit using a 450w controller on a geared hub motor just for reference. It's done a fantastic job so far of getting me from A to B only needing the wheel off for basic maintenance (tube changes for example). and each time I've checked to ensure there was no bending or cracking, and so far, there hasn't been any. That said, the dropouts on my forks are surprisingly beefy!!
@rickrandazzo 3 роки тому
Yep. He's running 1000w motor. Mine run 25 to 30mph, even hitting up to 35mph. You do not want to have a catastrophic failure at those speeds.

Nice work I watch your video a lot however my question is can this ESC works on a IGBT at 220v dc also is the 15 volt that drives the IC has to be isolated Thank you
@verrueckteriwan 6 років тому
Hey GreatScott, a good video, despite the fact that I am not big fan of E-bikes. I have a question though: would it be possible to make a energy recover system with that motor? (instead of breaking you use the motor to break and charge you battery again) Could something like that be used to charge the ebike without an outlet (I know that the efficiency will be horrible, but iam curious :) ). Thank you for making great content.
@CSparzo 5 років тому
Hey Scott, I think I found an error in your code and a reason why the motor wouldn't spin very fast. In your switch cases I think you have your ports D and B backwards for case 3, 4, and 5. If you look at the direction (DDRD) registers in setup() you are manipulating registers that you haven't declared as output, which also happens to be exactly flipped between D and B. I think the only thing you'll need to do is flip them back. Another reason the wheel won't spin quickly is because you only had it hooked to 15 volts. From the looks of it you'll need at least 36.

@bobalong131 6 років тому
Heads up if you haven't looked into it already. The front wheel electric motors will often turn inside the front fork either cracking it or rounding out the section and subsequently winding up all the wire and possibly losing the wheel. been there done that lol

@andycapo9you 6 років тому
The best conversion is the Tongsheng Or Bafang BBS02/ HD. Mid drive has the controller inside and looks much better on a bike. Yo also keep both original wheels that are most of the times better than the one that comes with the motor. You can also use your rear gears to get a more efficient ride. The screen on those mid drive motors are nicer too

@sss-tw3jh 6 років тому
I built one of these with a gas two stroke motor that drove the rear wheel, and an electric wheel for the front. It was two wheel drive. Electric gas human power hybrid. I took apart the twist for the electric kit throttle and figured out how to make it activate the motor at %100 power with just a switch, that way i could stuff that switch into a brake lever, and wire the cable for the carburator onto that lever. So one lever would drive both the gas and electric motor at the same time. I also had two switches next to that lever. One of them was the kill switch for the gas, the other was the kill switch for the electric. So i could change between front and rear wheel drive, both, and or human power. But then i just bought a motorcycle and stuffed that Frankenstein thig in a storage unit.

This is why I use Brushed DC. Simple PWM and no extensive electronics. May be less efficient, true but it's much easier to repair (both motor and controller) and cheaper.May jump BLDC once I get some funds and gain experience with current Brushed-DC setup.
