Re: Controller to limit PAS to 25kmh, Throttle unlimited

I just took a look at the documentation. Thanks a lot for the awesome work!

I see that it would be possible for example to limit throttle to 20kmh (parameter „no PAS“) and leave PAS unlimited.
But how do I have to set the parameters to limit PAS to 25kmh and leave the throttle unlimited?

Re: MXUS 3k noname Cover Plates

By the way, any idea why the mxus 3k seems to be cheaper and more available in Europe than in North America?

MXUS 3k noname Cover Plates

I am looking for black cover plates for the mxus 3k v3 without anything written on it.
In the EU this motor is cheap (299euro) but all of them have cover plates with 3k turbo written on it.

Re: Controller to limit PAS to 25kmh, Throttle unlimited

Thanks. Let‘s say the throttle would be set to 2000W peak and 60kmh max.
If reduction is set to 30%, power would be 1400W peak and 42kmh max for the PAS?
Or can it go down to 30% of the throttle values? (600W, 18kmh)

Re: Controller to limit PAS to 25kmh, Throttle unlimited

@zeccato: So you can set the speed limit independently for PAS and throttle for those EB3 controllers?

Re: Controller to limit PAS to 25kmh, Throttle unlimited

I think by just limiting the power, the motor would still be assisting above 25kmh (for example when pedaling or downhill). The idea is the following: To be legal there is no motor assistance at all allowed above 25kmh (at least in Germany). So PAS should work in a street legal way. Throttle would b...

Controller to limit PAS to 25kmh, Throttle unlimited

Is there any controller (for lower power ebikes) which is capable of limiting speed to 25kmh when only PAS is active?
When the throttle is engaged, the speed should not be limited at all.

Re: 3000W charger for bulk charging Lipos

Yes, I think the 1800W charger (or 2 in series) would be the best option.
Minimum voltage is a bit too high for 20S, but okay for 21S and 22S.

Just missing the ability of changing the output voltage without being that complicated.

Re: 3000W charger for bulk charging Lipos

I have modified 3000W server PSUs and 4010s at home for balanced charging and don’t want to carry that in a backpack of course :wink:
It should be something as simple as possible to charge while making a break.

Re: 3000W charger for bulk charging Lipos

Are they any chargers available that can output something around 80-100VDC?
Or lighter and more compact 42-58V 1500W-1800W chargers?
Cannot draw more than 16amps at 230VAC, so two 3000W chargers would not make sense.

Re: 3000W charger for bulk charging Lipos

Yes, it is possible to put two of these in series, but it would only be capable of about 3.7kW @ 230VAC.
Must be a really huge li-ion pack to take full advantage of the 56amps charging.

It would be nice if there would be a charger like this with adjustable charging voltage.

Re: Custom Double Front Frame Bag for Lipos

Wow, this bag is really huge. 3 inch wide is perfect, but what I need is something smaller.
The measurements of the Chinese bag were perfect for the setup I usually use (22S 16Ah)
But I will order one of these bags anyway in case I need some extra range.

Re: Torque Arm Derailleur Mount

I used some standard two-part TAs for M16 axles, but the axle can move a bit inside. Better I make my own TAs.
Would you put the TAs directly on the frame or put washers between the frame and the TA?

Re: Torque Arm Derailleur Mount

That is what I am probably going to do. I think one hole should be okay. Better be a strong bolt (high shear strength), since it'll be the only thing containing the torque of a 16kW motor. Maybe a grade 8? It is not the only thing. There will be a IS2000 mount torque arm on the other side. I plan t...

Isn't the hole in most frames a smooth bore with the threads being part of the hanger? Yes, but this frame is thick cromoly steel and the hole has a M10 thread.

Re: Torque Arm Derailleur Mount

Sorry, I forgot to mention that it does not have a derailleur hanger.
It's about 10mm thick cromoly steel.

It does not have rack/fender holes, but I am probably going to drill one.

Re: Sabvoton Throttle Sensitivity

Thanks. Do you know the resistance of the Sabvoton SVMC72150 mosfets?

Are there any waterproof 1kohm potentiometers? (which I would mount on the handlebar)
Another option would be to mount a switch on the handlebar and the potentiometer hidden.

Re: Sabvoton Throttle Sensitivity

I plan to use an ASI controller for my next project. Which motor are you using together with the ASI controller?

In the Sabvoton software you can set 4 values regarding throttle: min throttle voltage, max throttle voltage, middle throttle voltage and middle throttle phase amps.

Re: Sabvoton Throttle Sensitivity

The motor simulator is a very nice tool, but unfortunately it does not support field/flux weakening.
By the way, when using a custom controller in the simulator, I need to set a value for effective resistance. How do I measure this for the Sabvoton?
