New 1000w Geared hub MXUS XFC19

[CTYSSS]

I’m having issues with my MXUS XF19C, it’s making a noise. I suspect the cassette hub, which I don’t know how to remove. I’ve posted some videos and pictures here’s a link to my post.

Very interested by both Mac and Mxusxf19 i hesitate and finnaly bought a Mxusxf15r for the same price than the xf19 or close. Good motor to me (my first build) but it miss some power to me. Now i project to buy a mac or a little dd motor but i'm very curious about the potential of this xf19r. Knowing what is the best controller for example

40-43 battery amps I would say is the limit, you can bump up the voltage higher, to 72v, so you will get about 3000w.

XF19R 1000w version (with the bigger phase cable plug)

 

[Compoundbike]

The motor was very cheap 104 usd and 67 usd for shipping to Norway

I wrote to her and she didn`t reply... but that`s a great price.
Anyone else selling that motor with similar price tag?

72v really? That would be amazing!. I have a kelly controller kls7212s it could match but i think i would prefer a torque simulation one because i'm used to torque sensor even if mine don't work so well. I think a torque simulation one would be simplier with less bugs. I first thought improving my mxus xf15 with steel gears but i'm in contact with a seller to buy mxus xf 19. I'm hesitating but a 72v mxus xf 19 makes me dream

Thought I'd add my 2 cents.
Been running the xf19's as my new favorites. I am a builder in Boston area.

I run them on 48 volt KT controller 12 mosfet, I cut the cable at the axle exit and replace it with
Grin Cable with the 12g. phase and 7 control wires.
I did that because they easily take 2200 watt bursts and seem to run better and not hot hot cable to deal with.
The small section from end of axle to windings also stays warm at worst.

I stopped doing BBSHD builds in favor of these. A nice light K2 or Jamis frame and they pop wheelies and fly.

So far I got 6 MTB builds out there mostly with hunters, one guy who runs trails.

KT setting C1 I think, raise it up to 90 and that opens the gate.
I do cap the current to about 1600 watts for customers....

Amazing what is this controller? I'm very interested by this one: http://www.topbikekit.com/t12h-36v48v-1000w-40a-torque-simulation-sine-wave-controller-for-ebike-p-833.html

It's a torque simulation controller. I think it can be linked with this small display i already have: € 30,48 4%de réduction | Affichage intelligent du panneau de commande pour vélo électrique, 24V 36V 48V KT LCD LCD4 ktlcd4, pièces de contrôleur KT

What exact model is your controller please?

 

[Kajman]

Guys, anyone have idea of rpm difference between 36v and 48v version? Nice motor anyway.

 

[amberwolf]

Do they rate them as the same wheel speed (in same size wheel) at that voltage? If so, there isn't an RPM difference.

If there is a speed difference stated, then you can calculate the RPM of each version knowing the speed and the wheel diameter given for that speed.

If no wheel speeds or RPM are stated for either one, it would require experimental data to find out.

 

[Kajman]

No data, that's why I ask I will have to take it on the table.

Did you buy the stock XF19r with no special winding? Does report speed at while coasting? Is there a temperature sensor? How are they still doing?

 

[sinkking]

It is easier to pedal this or a bbshd?

 

[sinkking]

No one is reporting speeds?? I'm wondering what speed it gets at 60v 40a and how easy it is to pedal vs a bbshd

To go high speed you have to fight two things:
- Controller eRPM limits, IE you need a specialized controller for this motor.
- The motor's low efficiency relative to a MAC or DD prevents you from running those high speeds for a long period of time, even if you achieve them.

You want high continuous speed? look anywhere other than at this motor.

I would assume the motor has a freewheel and there shouldn't be any significant drag while pedaling.

That is disappointing. The only geared hub motor that I know of that does high speed continuously is the one on the Wired Freedom fat bike but I want something for a MTB wheel.

 

[neptronix]

What's your definition of high speed?

 

[sinkking]

What's your definition of high speed?

37-40mph

 

[neptronix]

Yeah you want a direct drive for that. Unless you have a fatbike frame and then you can install some of these very wide geared motors that are out lately.

 

[Zorroavelo]

I've bought it and mount put it on my bike, it's noisy and i now have a clutch issue. I will try to buy another clutch and some copper gears before putting back the 60amp controller

would statorade help?

 

[neptronix]

Statorade doesn't work for geared motors because it can't help you get the heat inside the case to the outside of the case.
An ATF ( or other fluid ) fill that drips everywhere is your best bet for improving this efficiency/thermally challenged motor. Most people don't like that.

If you like this motor and want more power, try a MAC or GMAC.. those have higher efficiency stators and therefore don't make as much internal heat, so you can flog them longer

I hesitated for a while between MAC/GMAC and mxus xf19. I finnally choosed the mxus because of the price, the biggest reduction ratio and the disponibility at that time... The mac was rare and hard to find at a good price and the mxus was only 200 dollars with shipping. I don't regret it but i think i made some mistakes like accelerating with throttle when the controller i've used was running the motor backward. After that i understood the concept of self learning on this controller(JRAHK controller). After using it with 72v and 60amp i have now a noise with the clutch. I'm talking to some sellers to find copper gears but i only found steel gears. I would prefer non ferric metal because of the coils and magnet... My finnal goal is to use ATX oil to keep it not too warm, i will probably weld the clutch or buy a "no clutch" planetary reduction if it exist.
