VESC Flipsky 75100 Pro V3 MSUX3k & 72CV 40ah HELP

[Ahagie]

OK, so Im making the First (and only) Michael Blast 3k 72v Greaser Cafe Racer lol. Its nebula figured out the rotor issues everyone has on this motor and it's all wired up. The issue I have is

What is the FW I should use for this (Ver)
Which Temo sensor molex should I connect (There are 2 on this motor)
What are the settings for the MXUS in this controller?
Isn't there db or chart that show common hub motor settings for this controller or any VBESC controller?
I assume I only need to set the battery and motor to get this going? Ive had this motor working on a Sabaton.

Doubt thats 72v 40Ah in a downtube battery

The VESC wizard will find the motor settings automatically, if you have issues with tuning read this: VESC Tuning tips. That is a pretty small controller for a motor that size but I guess that depends on what you are after, will still go along nicely but you won't be pushing the motor very hard at 100/150 phase amps.

I think the same thing. but I have it and I know it's at least 72v lol.

Unfortunately it's not. thats why im asking. it shows Over voltage error. I was thinking of upgrading to the 75200. thoughts? Could it be too much motor for the controller to push? With the Hallomotor 150a controller it upshot just fine

 

[scianiac]

If it shows an overvoltage error you probably just have to set the voltage range correctly. Motor settings > General > Voltage and Motor settings > General > advanced. It's probably the latter maximum input voltage is set too low, should be slightly higher than your maximum battery voltage.

The 75200 would be more suitable for a motor of this size but this also depends how much power you want and how much power your battery can output, no point in a larger controller if the battery can't keep up. Either way these cheap VESCs are hit or miss, they can be finicky to tune due to how cheaply they are made. Still perfectly possible though and while they are not as reliable as better models they aren't terrible either. As with anything cheap, easy, reliable. You can't have all 3.

LOL I hear ya. same with IT Fast, Cheap or feature filled, pick 2...My limitation is the space to mount. its SMALL her sis what ive found on the motor and batt. Id think SOMEONE would have a MXUS setup on VESC that they could chime in?

8 cells in parallel meaning 40/8=5. 5Ah in a 18650 format, I would like the same cells please my 21700 are trash compared to yours 18650

 

[scianiac]

I mean they are not 5ah 18650s, the specs are wrong/lying and without knowing the cells in question how much power you can pull from them is unknown so reaching those power numbers of the motor may be totally impossible.

I mean did you run the motor setup wizard and the input setup wizard? You pretty much just follow the steps and if you aren't sure about anything it asks you, ask here. That should get you to a basic setup. My experience with these cheap VESCs and most motors is they often do run just fine from detected settings at lower power levels, I think that's mostly lower in terms of the motor so a big motor like this driven pretty conservatively may not require any tuning.

Here is the Wizard I Ran (Sorry had top post delete a few times lol

That should be just due to the settings in Motor cfg > General > advanced, once you chance the max voltage to something slightly above 84v (the fully charged voltage of that 72v battery) and hit write to save the settings, then rerun the wizard and that error will go away and it will finish the detection.

OK I found the Max settings. But I still get an error. (see attachments please) Im SURE were close. The motor has already been tested with a diff controller and it works. Im sure its something im not selecting correctly.

Also, Ivre had to battle the every popular "Disc Brake clearance" issue one th 3k. but that is fixed with some Avel washers to pouts it out about 4 mm on each side. Then the chainring is out of alignment because it use to have a 7 speed but they hub wont first that wither will the 135mm drop out lol. so I switched to the single speed and its off by 10mm! Seven after got spacers. so now Im switching to a 3 speed cog to see if I can get just one gear over far enough to work (DCa low, has to be a pedal bike to be considered a ebike still) well see today if that doesn't work im going to have to replace the spindle with a shorter one to bring the changing and the crank inward. IU don't think the 3 speed will have enough thread on it to work ugh

 

[scianiac]

The same error or a different error? (don't see any attachments on that post)

OK so I looked up what you had said since I thought the same thing and lo and behold...id need 400 (Damn) cells for a 72V 40ah battery! UGH. So im going to open this thing up and see how many 18650 cells are actually in it. thx

You should also see if you can tell what cells they are, if you can see any writing on the side, that would determine how much power you can pull from them.
