QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

Do I accellerate faster with 20s or 22s?
 
I need to know how many RPM the QS4 takes per volt (RPM/Volt).

Thanks for answering.
 
If you fabricate one of these motors into a mid motor setup. Lets say the motor has 100nm of torque (a random #), and you put a 25 tooth gear on the motor then a chain goes to a 10 tooth gear on the crank (random #'s here) would not that be a 2.5x increase in torque, so 250nm, while having it a 2.5x decrease in speed. Only of course if you have the rear cassette at 5 tooth as well.

Lets then say you shift from a 5 tooth gear in the rear cassette, to a 10 tooth cassette. You are right back to 100nm.
 
quality of winding,
not cleanly Work, broken and chipped insulation. (By two Motors) F..K
and therefore my Adaptto Kill (2R2-Resistor)

who still has problems with QS and Adaptto ???
 
woah!
wait a mo. are you sure the chipped varnish on the windings could have or even be capable of blowing your adaptto resistor?
i would suspect not, unless you had your halls wires in direct contact with motorcase or phases also?
i would have thought it more likely that a bad solder joint or previous fault in controller would be more likely culprit for blown resistor.
 
So, I talk with Oleg (Adaptto Support) the problem with the resistor is, if a defect is present (minus Problem, Phase Problem)
I have 2 Adaptto Max (1x Brand New) and (1x From my Raptor) both defective (Halls error 2)
AND Two New Motors.......

So Adaptto go back to Moscow, Repair And Two QS205 V3. And my raptor stands again

it would be nice, if it were true

holy shit! :shock:
ARE YOU SURE there was no problem with the hall wires or the solder joints inside the sensor connector?
what does the multimeter show if you measure between the phases and the stator iron (or measuring insulation resistance)?
because i also cannot understand why the resistor should blow if there is no varnish at some areas of the single strands, and from the pics it looks like nothing has shorted (otherwise we would see melted copper).
On mxus motors i have seen strands with chipped off insulation as well, but never had problems. If there is no insulation, it doesn't mean there is automatically a short. a short only would be if two strands side by side having no insulation and both are from a differnt turn count.
 
between Phase and Stator "No"
Between Stator and Minus Hall and everything (Metall) "No"
the soldering is Good, but the individual strands that are damaged lie on one another, the in individual sectors the magnetic field is disturbed....
 
Did a teardown of my SSC048150 and its using 24 4110 FETS meaning up to 96V 150 A. Check aliexpress. I see the qsmotor store still has some models available. I paid about $300 give or take, shipped to Oregon. Shipping will be the same for WI.

Hello Sansander.Ebike,

Sorry for the puzzled.
After checking with our Engineer, the damage of strands will not lead to short circuit.
The inner strands might also damaged, and short circuit.
PS. We will try to avoid the damage of strands, anyhow it's inescapability.

The stator and assembled motor are both under leaky test before delivery.
So there is no possibility that the motor is short circuit once received.
Here is the picture for reference.
Leak Test: Stator, 1200V.

2.jpg
Leak Test: assembled motor, 400V (to protect hall sensor).
3.jpg
4.jpg

Due to your discription, the motor is ok.
The controller didn't work because the setting of V2 & V3 is different (e.g. phase sequence, offset).
Some customer ask us about matching with Adaptto controller before.
As we didn't test with Adaptto controller, we have no idea so far.
Finially, the customer made it by themselves, please refer to below link (From NYX).

PS. Did you get the motor from Patrick?

Btw., the motor is on Sale Now.
The 205 50H V3 Motor & SVMC 72100 controller is on sale within 24h (only for samples, from 9:00 p.m. 2016.3.19 to 9:00 p.m. 2016.3.20, Chinese Standard Time).
The original cost of the motor by paypal is $290.06, now you just need to pay $273.5, and Yuqiu Three Speed Freewheel is for Free.

For 1pc 205 50H V3 motor, EXW $273.5 by paypal.
For 1pc 205 50H V3 motor+1pc SVMC72100 Controller, EXW $471.5 by paypal.
For delivery cost, we will check delivery it before delivery.

Hi Vito,
which is very annoying for me.
a leak test It is not possible for me no devices for this.

why are you doing the test befor and not on the finished product with 1200V ? because more production steps follow......

as you can see on the Pictures stack Stators Possibly caused the damage ?

yes this motor Is from Patrick. You can send him a new Motor ?

Sans.
 
Nice vid^^ would be interesting to know how efficient it is at those speeds in such large wheel.
i don't think it operates at peak eff so there should be room for even higher continuous power when laced into smaller wheel.

the problem of hub motors is the poor heat emissivity and aside form the mass which only delay overheating, there is no big difference between a very small 205mm stator motor and one with a wider stator if both run at same efficinency, because the surface area which is important for heat dissipation isn't much higher on the motor with wider stator.

thats right. an additional leak test of the assembled motor would be reasonable.

about devices that can measure leakage: there are mulitmeters used for testing the leak or insulation resistance of wires in buildings and houses. in the company i'm working we have one that can measure up to 500volts. maybe a local electric-company in your area has such device.

Thanks for that excellent video!

It is very informative. You get very similar data as i got with my Giant and the crystalyte 5303 and modded 18 fet infineon controller with 24s lithium in 2011. it clarely show that the motor temp is also affected by the wind coming very fast at 100kmh and cooling it on the motor case ( rotor) normally at the same power but very low speed and hill climb the motor would heat faster. It would be very nice if you could put these data on a graph using that video and the timeline ex: time on X axix and motor temp on the Y axis..

Some of you might be surprized but at that speed a motor like that is in a great efficiency area in the graph.... 8)

what kv motor do you have to get 100kph on ~40v?
Click to expand...

Ihe is not running at 40V.. see the details in the video.. he run 20s and a sabvoton 150A

i think he just have the cycle analyst rading half voltage but twice the amp... why...? i dont know...

the motor kv is 11. please read the video information on YT :wink:

Doc
 
its just for the police...looks better in a official range. (~48v)
this is a "onboard" feature from the cycle analyst. to get real wattage, divide shunt by 2
yep you got doubled amps, but thats ok for me because i dont need really amps. Sabvoton is open to everything he can squeeze out ;)
Underrated biatch. Wish i could get a sample with open firmware.

Can you explain how i can do this?
Maybe a pm if it is too much offtopic.

i would take alot of videos to compare with the old 9kv cro in a raptor. every time i ride with my buddy iam still wonder why his cromotor heats up so fast.
if he reaches 120°c i have some a bit over 80°c.

we did allread a new hall angle test, switched the bikes etc.

Higher kv motor have lower phase resistance witch mean less heat..

usually high kv motor make themotor to run cooler but controller run warmer...

if the motor run fast but use the OVS it will heat faster... if you use a higher kv motor and more amp or higher battery voltage and NO ovs it will run cooler.

Hi Sans,

1st, For assembled motor, there is hall sensor, which might be broken in 1200V (so we choose 400V) for the test.
And Well noted, I just state what QS do before delivery.
Which means there is little possibility short circuit for QS Motor.

2nd, The damage of strands will not lead to short circuit.
PS. We will try to avoid the damage of strands, anyhow it's inescapability.

3rd, I don't think the controllers are broken.
The controller didn't work because the setting of V2 & V3 is different (e.g. phase sequence, offset).
It might run with Cromotor, but the setting should be modified to run with QS 205 V3.
In conclusion, we don't have a plan to send new Stator or Motor so far.

Btw., is anyone know the correct setting of Adaptto E-max maching with QS 205 50H V3 Motor?
Your help will be highly appreciated.

Best Regards
