Vito: Thank you for your kindly information.
It could be 10"X3.0" 3000W 205 50H V3 Hub Motor (maximum), the max speed could be 70-80KPH.
For details, could you please advise your email address?
I would send it by email.
Awaiting for your comment, thank you!

Dear All,
We are going to develop 205 E-bike Hub Motor, 135mm dropouts (more than 205 28H).
Do you have any suggestion on the magnet height, power, speed, voltage, suitable freewheels?
Btw., I have updated the page of "QS 205 50H V3 Motor, Most Powerful Direct Drive Hub Motor".
Refer to the link, https://endless-sphere.com/forums/viewtopic.php?f=31&t=65972&p=1082427#p1082427

I would like to see a 40mm wide motor similar to the Crystalyte HS40 motor's, but with lower weight...i.e. less than 7.5Kg if possible.

Are you going to use V2 "EXPORT" or V3 "EXTRA" stator?
I personally would vote for a version with 35 or 40mm magnets.
As already mentioned it would be great if QS motor would also focus on reducing the weight.
Any plans for that?
For instance the weight could be reduced alot when using a separate steel ring (for magnet return only) which is mounted or pressed into an aluminum spoke flange which is than again fix coupled with the sidecovers. Also the magnets don't need to be sticked side by side. There can be a gap between which also means lower weight.
I really like the design of the bionx motors. IMO thats quite the optimum design for a direct drive hub motor:

Hello Doctorbass,
Thank you for your sharing.
EVOKE use QS 16"X3.0" 273 50H Hub Motor, the axle of the Motor is customized.

I would also add; make the axle bearings as large as practically possible. This then allows easy addition of large phase wires, or water cooling options.

Kinda feeling bad for Justin here (20mm thru axle). Seems like he does the R&D and other manufacturers get free access to it here for nada effort. :|

Vito you'll recall I did ask some time back for a 35mm motor with V2 stator or better. I would still think many of us would want it.QSMOTOR said:

Which settings are you after? There are literally few dozen options in the settings.litespeed said:

Angle correction and the other advanced settings.
Just for comparative measures.

Much larger axle and bearing on the wire exit side with a customs large disk rotor would be a dream... Im so sick of stripping phase wires.

Yesterday I have added 5ml of ferrofluid at my QS205 30X4T and this is the thermal conductive paste I used to seal the side covers.
Then at the sunset I went for a test ride on the beach in deep sand and the first impression is that stuff works
because I reached the same distance as I rode before with a lower motor temperature This night I will try it on flat road at full throttle with OVS = 3° at about 8,5KW and see what I have holding 80-85 Km/h for about 4Km
These are my current settings:

nice one BB!
im keen to hear how the high power tests go.
I love the idea of the thermal glue on the covers, should help to keep the magnets cool, and with the fluid,should be very effective at reducing stator temps also now.
some aluminium finned heatsinks screwed to the outside of the covers would be good too. the new QS motors are good for that because the side covers are flat, like the old clyte x5 series

I might order a 205 for my old bomber soon as well. Would be nice if shipped by default FF coated like this.bigbore said:Yesterday I have added 5ml of ferrofluid at my QS205 30X4T and this is the thermal conductive paste I used to seal the side covers.

Thank you for your advise. We will consider about this.
135mm dropout for 7 speed freewheel (cassette if possible), V2 or V3 design(aluminum stator) with 4mm2 phase wire.
To check the higheset magnet, and to reduce the weight as best as we could.
