Impossible to say without an oscilloscope. Why bother? Motor runs well with this setting.
Controller overheating on sand or hard hills :)

Never had it get warm even with repeated drag races on 200A. There’s no reason to change anything.
Ride on!

However I want to try it without flux weakening :)
But don't know how)))

Here is my config and rpm https://vimeo.com/374241692

How do you mean you don’t have field weakening?

Thought this is applicable only when "sport mode" activated.
Thanks, will check.

UPD: yep, this is it, thanks a lot

Nice that thread shifts to flux wekaning again.
I'd really like to gain some more understanding of those values
  • Flux-Weakening compensation
  • Flux-Weakening Value (in 6 different positions)
  • The %-Figures in the Three-speed box
  • Phase current

I think the phase angle shift setting at 60 degrees is already slightly advanced from neutral. This creates field weakening.
Ah, :!: :?:
When I look to this figures, labelled "without flux weakening" by QS
Image
in my eyes they resemble typical characteristics of flux weakening, anyway:
  • constant torque only up to ~ 1500 rpm
  • hyperbolic falling torque and ~ constant power between 1800 and 4000 rpm
Just looking at the chart, I might have said that flux weakening were active above 1500 rpm.
Might the advanced phase angle shift be the cause of this behaviour?

But anyway, what does the 100%-value in the speed settings refer to?
no-load rpm? which is 4350 in this case?

I have a small DS203.
OK, it's more a toy than a professional grade osci, but I could even attach it to the bike wihle driving.
Might this help to gain more insight to all those opaque figures we keep on questioning here?

Its got 2 analog channels and another two digital ones.
So I cannot measure eg hall, phase voltage and phase current the same time.
But I think I could try to use hall voltage to trigger one of digital inputs so I might get phase angle relations that way for all three values in consideration.

I think I'll provide a shunt in one of the phase wires. Well, the wire itself may do the job.
I have some hall based current sensors and current transformers as well, but I'm not sure how they affect presicison of timing.

hm ... the phase terminals will jump from 0 to V-batt, maybe plus some spikes.
Shunt voltage is in the mV, and halls are said not to like overvoltage.
So still some thinking required, regarding signal conditioning....

Such a nice build.... nice
between speed 2 and 3, have you noticed any difference in torque ??

not yet, there was only one ride for now)))
however in theory, 3rd gear should have more rpm and same torque

That's the spec, that' where it starts and where the settings are supposed to go to.
As people said, it all goes together, holystick or so, they called it :lol:

You run the QS 138 on the Votol 150?
May I ask you for your transmission rate and your battery data?

Reduction drive is made to decrease rpm 1:2, then sprockets 15:50, so in the end 6.7 reduction ratio.
(may be later we will replace rear sprocket to 52)

Battery 22s, 55Ah (prismatic)

Thanks my Friend. So you are using 22s on votol em150 ?

UPDATE : LOL... when I try to import your parameters in the votol software, it gives me some crazy numbers.... very buggy software

@larsb Which manual are you reading from?

I've been using the 2000w motor with em100 controller a little bit now but cannot seem to make the throttle response sharper in controller settings, is this just the nature of a low kv motor without reduction drive? I have switched off soft start which helped a bit and have also tried softstart enabled set at 16 which seems the same to me.

when riding it doesn't feel like deadband in the throttle but like a lagged build up of power which feels quite unexpected and hard to get used to, has anyone experienced similar?

I have an older program than most and the trottle setting does not work.

Check if it works for you by setting some big changes - does it have effect?

Thanks ? Didn't you run 22s og your build ? Because your voltage settings says otherwise ?

No, it doesn’t
89.5/20 is not a normal lipo overvoltage but it fits 21s or 22s

btw folks, do we have a separate thread for Votol EM-200?
or can we discuss it here?

Finally...

First power up, of the Em150 - qs mid drive 3000w combo......

I could change the throttle endpoints, without any problems.... So nor my settings are "start throttle" 0.5v and Full speed is 5.02v, and it seems to work perfect.
As of now, i´m hitting arround 6000 rpms, in "sport" mode, what do other have ??
Thanks
