For 273 40H 3000W spoke hub motor (diameter 317mm), we're making sample to test, which estimated to be ready next week.
If any news, I will keep it post in ES.

For details, please refer to attached "New 205 50H 3000W Spoke QSMOTOR Quotation & SPEC" & "273 40H 4000W Spoke QSMOTOR Quotation & SPEC".
Btw., 273 40H 4000W motor is better for sure if the axle flat could be 12mm.

Best Regards
What is the estimated weight of the 273 40H motor? Can the 12mm flat version axle flat really handle all that torque the large 273mm hub motors make? This motor was originally designed for scooters not ebike so will cutting the axles flats down to 12mm compromise safety? I know your axles are made of high quality steel than other suppliers, but do you actually do load testing on the axles in both direction (to simulate regen braking)? If so how wide are the clamps (simulating a dropout) used during the test to hold the axle in place?

Thanks

Am I wrong or if the steel is heat treated even a 10mm axle should handle the extra torque?

The datasheets are a bit off, though, as above, the measurements are the same even for the 8kW version & various other inconsistencies...
Let's give them a while to edit in the details into what looks to be WIP.

You are talking more than 300 Newton-meters of torque with the 273 series.

Here is a simple test but does not simulated repeated cycling, especially with regen

Don't really trust data sheets and simple shear force calcs. you need to test to failure with a hard edge dropout applying the force in one direction and then the other to simulate repeated accel and regen. The original engineer spec'd the axle for a scooter and then you go and cut it down to 12mm flats for use with bicycle dropouts without testing? If we need to mod our frames for larger dropouts so be it, but don't sell something that is not safe to use. There have already been reports of cromotors with twisted axles and then make much less torque than a 273 motor, but the cromotor design is pretty bad (see below), so may a well designed 12mm axle could handle more torque

I see.... so the problem isnt the 12mm flats its the way they route the phase wires. A 10mm solid axle should handle the torque just fine if they dont grind half of it.

Hi, sorry for my late reply. Oh, I see. The max. Erpm for Sabvton controller is 30000. For APT controller, no problem for Erpm <= 40000.

What version of the QS 205 v3 extra 50H motor have you guys ordered? I am not sure if I should order 3T or 5T version. As the copper fill seems to be the same. Motor will go in motorcycle wheel 17 or 19".

Image


What would be great match controller for this motor? I was gonna use the adaptto max-e but due to cashflow problems I must look for cheaper alternatives. Anyone tested those new Kelly FOC controllers?

I am aiming for peak performance >10 kw - 15 kw. What controllers will handle that?

QS 205 50H V3 Motor, Most Powerful Direct Drive Hub Motor

Post by QSMOTOR » Aug 08 2015 9:13am

Dear all,

Recently we did some update for our 3000w 205 50H V3 spoke hub motor to improve its waterproof
1. QS make dual holes for axle glue instead of single hole which make axle glue fill up with phase wires
2. Add heat shrink tubing to lengthen PVC silicone fiberglass sleeving for better waterproof
3. QS change better side cover glue and implement glue automatically (instead by hand)

More details about waterproof, pls see this link: viewtopic.php?f=31&t=65972&start=1100#p1385746

We have post QS 205 50H V3 Hub Motor for a long time, and thank you so much for your guys support.
The hub motor is more and more popular throughout the world.
I would like to do some modification of the thread for better understanding.
QS / Quan Shun, 205/50H V3 "Extra Type"
The QS motor company has also decided to begin selling their E-motorcycle hubs with axles that that have been modified to fit a bicycle.
Their motor phase wires are thicker than the other motors listed, and their axle design is stronger.
The stator width is 50mm, but also…the stator-teeth slots are deeper for more copper-fill, and all of this adds up to a motor that can take more watts.
Said by "spinning magnets" in electricbike.com. https://www.electricbike.com/large-hot-rod-hubmotors/
QS 3000W 205 50H V2 Motor is a robust, high power, high torque motor.
Suitable for all who want to ride fast. It can handle a lot of current and will nto overheat that easily.
It can withstand up to 10kW short boust of power. It is one of the most popular motors on the market and is also found as modified version (for ex. Cromtor etc.).

Performance & Testing
Here is two performance curve/test report, with SVMC72150 controller.
For 200A Phase current, EFF 90.9%, Peak Torque 172.6N.m
For 350A Phase current, EFF 91.5%, peak Torque 179.5N.m, max output 7227W.

If you have more information or suggestions about test data, please feel free to contact with us.
PS. I plan to set about 190A, 72V & 96V to test peak output of the motor.

100V 200A Power Supply, 300N.m Dyno
Image
Temp Sensor of Multiplex Temperature Tester, same position as thermistor KTY83/122
Image
Sabvoton controller APP could display precise temp of motor as the Multiplex Temperature Tester.
Image
Phase Current 100A, Last 36s, about 90N.m, the temp go to 150℃.
Image
Phase Current 150A, Last 20s, the temp go to 180 ℃, and there is smoke.
Image

Conclusion.
For phase current, 100A 36s, 150A 20s, 220-240A, 2s.
After Chinese New Year, we will keep on testing 24X5T winding motor when come back to work.
E.g. Input 72V 150A or even 200A battery current...
More testing on V2 18*4T Winding...

Suggestion.
For QS 3000W 205 50H V3 Spoke Hub Motor, 24X5T Winding.
Phase current, we suggest to set 200A (10s), 220-240A (1-2s).
For battery current, it could be 150A (72V).

For other winding motor, we suggest to set max phase current 40 Time of Wire cross-sectional area (10s).
E.g. 24X5T winding, the wire cross-sectional area is 24X0.204=4.896mm²
Peak Phase Current 4.896*40=195.84A.

Electric Motor Kits
Controller
Most Customer choose Adaptto MAX-E controller, but I have little understanding of the controller.
Some customer ask me about the correct setting, I will try my best to get it.
Meanwhile, could you please help me out and advise some information on this?

I was totally looking forward to this motor but not sure about putting a 40 lb motor on the back of my bike. That is a lot of weight and then to add the weight of a motor rim, 10g spokes and a big tire and you'd easily be in the 52 lbs category in no time. I had no idea I'd be adding 20 lbs to the back of my bike over the 20 lbs I had on there with the MXUS. I guess I could just add 10 lbs going to the 205 but then wonder if that is enough over the MXUS to warrant the change.

There is so much compromise with hub motors sometimes it hurts my head trying to figure the what seams like "quantum physics" of what best fits me scenario!

I'm off to think some more!

Is there any way you could do a mid drive? If you could get the weight out of the hub it would mean a lot. If you could do a mid drive like like this then the weight would not affect the handling so much.

If you are going to do a mid-drive then select a lighter, higher RPM motor for overall weight reduction.

I probably need to take a step back and really think about what I'm looking for this bike to do for me. Really think about the power requirements I'm looking for to see what I can live with.

Thanks for the ideas.
