Hi,
I am about to order a 36 v Cute Q100 motor and need to decide on 201 or 328 rpm version.
I already have a Cute Q100 24V, 328 rmp (front hub) and would like to know if it is possible to swap the gear set "planetary cog wheel unit" between this hub and the hub of a Q100 36 V, 201 rpm hub ?
(i.e, resulting in one Q100 24V, 201 rpm and one Q100 36 V, 328 rpm motor)
It would be great if this is possibe as that would allow me to find the best gear/speed ratio by real life testing.
Thanks for your help
You swap the entire core of each motor. The housing is the same. Here''s a photo (above) of what's inside.The core is the bit in the middle at the back:
Thanks d8veh. I understand that the core can easily be swaped. It is just that I am now trying to understand if I can use the gear cogwheels from my "24V, 328 rpm" unit and move them onto a "36V, 201 rpm" unit. If that would be possible I would order the "Q100 36V
201 rpm" unit and I could then first test the 201 rpm configuration
(swap the complete core) in real life on my commute path and if it is too slow I could instead use the cogs from my current "24V 328 rpm" unit and test that. If it seem too difficult to swap cogwheels between a 328 and 201 rpm unit, I think I would order the "36V 328 rpm" hub instead (I would prefere speed over climb, although I have a few hills and it is sometimes quite windy on my path to work).
(I realize that the 36V 201 rpm hub with a 48V battery may have been the better option, but now I have to live with my 10 Ah 36V LiFePO4)
I have searched this and other forums for info on the cogwheels of various Q100 versions but found nothing useful so far. But I realize, if anyone, you may have the experience I am looking for here.
I have opened up my 24V, 328 rpm hub and the gearset looks very similar to that in the 36V 201 rpm unit seen in your picture. Counting cogs on my "24V, 328 rpm" give the following;
-core axis wheel=15
-nylon wheel, outer part =36
-nylon wheel, inner part=23
-metal "coronal" cover wheel= 78
If I have done the math correctly (36/15* 78/23 ) this give a gear ratio of 1:8.14
OR, could it be that the gear wheels of a 24V, 328 rpm hub has exactly the same metrics as those in a 36V, 201 rpm hub ?
How many cogs are there on each of the cogwheels of a "Q100 36V 201 rpm" front drive unit?
Anyone that know what the "gearbox" of a Q100 36V, 328 rpm front drive unit look like ?
Again, many thanks for your efforts on this forum.

Hi again, I just realized that I may have misunderstood the difference between Q100 201 and 328 rmp versions. I have thought that torque and speed is adjusted via the gear ratio but just realized that this might as well be tailored by different winding. Can anyone confirm that gear cogwheels are exactly the same on all Q100 versions (24V201rpm, 24V328rpm, 36V201rpm, 36V328rpm) and that it instead is 4 different winding configuration that result in 4 different Q100 versions ? Thanks.
