No, not fun at all. Glad youāre OK!
@wafflejock @Saturn_Corp LoL yes that is the correct way, but I find it much easier to plug my information into the calculator linked from the top of forum.esk8.news.
Letās say for example it says Loaded Erpm is 38556 and Loaded Speed is 42.8km/h
Then itās real easy. If you want to limit it to 35km/h then you just use the ratio
38556erpm * 35km/h / 42.8km/h = 31529erpm
Limit it at 31529
Yah knew this existed somewhere but slow day at work
Any chance I could get a list of good esc to use for dual 6374 motors and even an order on best to worst would help a bunch
Thank you.
There are some ideas in here
This is going to be largely subjective to answer since it depends on what you consider good and bad things. Some people can stomach any price and waiting for a quality part, some people want easier to replace individual pieces others want more integration, it really depends on what you want in terms of what is best.
Do you care about being able to configure it yourself?
How important is price?
How important is immediate availability?
Would you rather replace a second ESC or have everything built in one?
Are you looking just at different versions of VESC or across all ESCs (do you know the difference?)
What are the power requirements?
Do you want to run FOC mode (again do you know what this is does it matter to you)?
Configuration: I guess Iād like to have the option
Price: I donāt mind paying up for something good.
Immediate product: I wonāt mind a little wait 1-3months max but not anything more I reckon.
āAs for replace second esc or all in oneāā¦ im not too sure I understand this question
And version of esc, power requirements and foc modeā¦ I do not know this stuff.
Sorry bit half assed question on my end asking for a list of esc without really knowing what I want.
The fact that you addressed it nullifies any harm
Focbox unity
Vesc6
Flipsky dual + version are all viable options for you
All good no one knows this stuff up front just wasnāt sure how much youād dug in already.
Regarding getting a two in one vs individual ESCs there are boards that directly support dual motors from one PCB, so thereās one battery connection into the ESC and 6 phase wires for hooking up two motors. Other option is you have two individual ESC each with power going into them from battery (parallel connection to battery from ESCs) and then each drives one motor. Advantage with two separate is if one dies it doesnāt mean replace the whole thing and can run on one motor while waiting on replacement ESC, disadvantage is more complexity in wiring and configuration of two things instead of one.
For power requirements itās a really hard thing to know ahead of time, it depends on weight, location (hills), ride style, etc. but can find data here or just searching around for metr.at logs of other similar riders in similar locations. Iām a small guy on flat land riding urethane with one motor so power requirements are minimal: https://metr.at/r/6EGoI
https://calc.esk8.news/#/0 <-- can help get some idea
also an average rider will use around 10-12Wh of battery capacity per kilometer so if you are heavier than average expect higher draw, if you are average or lighter then can expect less draw, this also depends largely on how hard you accelerate and if you are riding up hill or not.
FOC mode is an option on VESCs but on some versions of VESC is known to cause the board to blow out so not advisable. It basically makes the motors run quieter and a bit smoother but less top end speed.
Edit thought I mentioned it but just read my post and forgot the ecalc linked at the top of the forum here can help with figuring out your numbers, let us know if something there doesnāt make sense or you canāt find the numbers.
Hello im looking to build a electric skateboard for about 750 what will that give me
Start by reading this
And if you believe DIY is right for you
This is a good place too start

Anyone know how to tighten the cans on TB 6355 motors? I think it has something to do with the circlip but Iād like to hear from someone experienced before messing with it, thanks.
I think I might have a broken magnet, Iāve never opened one of these up beforeā¦Do I need to disconnect the motor from the vesc to open it up? I only ask because it would be a b*tch to remove all the wire guards from the phase wires to disconnect them, would rather avoid this if possible. Also how do I remove the c-clip?
Do any of these magnets look broken to you guys? The inside of this can looks fine to me I canāt figure out why my motors making this fucking noise!
They donāt look broken, but theyāve definitely been rubbing a bit. How tight of a fit was the shaft in the can?
Replacing the stock set screws with some class 12.9 ones can help, and loctite 680 as well.
I noticed in your earlier video that the can seemed a bit wobbly, and guessing by all the marks on the outside itās been hitting stuff pretty constantly, and so it may have basically wobbled out the shaft hole in the back of the can. Iād try using some shims or something to make sure the can is perfectly centered on the stator/shaft, replacing the screws with class 12.9 cup-point setscrews and then adding some loctite 680 and letting it set up overnight. If thatās the problem then that should fix it, but it may not be a permanent solution - loctite is only so strong. You may end up having to get a fresh can or maybe a new motor.
Do you have an esk8 already or will this be your first?
Is there a magic way to get alienpowersystems to answer emails? Its been over a week with no response on why my order placed on the 9th of july is still āprocessingā they claimed in the last email that all July orders were being packaged and shipped a week ago.
Is their tracker just bad?
The order was simple, just 2 motors that were in stock. Anyone know what might be wrong? I want to give APS the benefit of the doubt here, but Iām getting a tad bit worried
Yep
This is the not-as-good way
And this is the best way Iāve found
And none of this is specific to TB motors ā I have yet to find any esk8 motor where this isnāt a weak spot
Iām looking at
I know QC with Flipsky is a bit of a gold mine but what do you think about this running say a 12s4p samsung 30q and two 6374 (95kgs) @wafflejock
