Nanjing far driver controllers

Post by j bjork » Jun 09 2021 5:39am

These start to turn up here and there on the forum.
It seems like they were only available in China before, but now they seem to be available on more places.
Like qs motors:

The specs look a little strange, max 110V on a 96V controller?
Is it really true, 1800pA on a relatively small controller?
Anyone with experience of these controllers?

I haven't seen them before but they look interesting; it would be awesome if someone cracked one of them open and did a teardown

We installed one on a friend's bike and it is really great. I would definitely install one on my motorbike if I had the money.

Interesting, please tell us more :)
Is it kebekua on the forum you are talking about?
It seems he has had one of the biggest versions for about a year.
He wrote he would get back with a report, but I haven't seen anything.

What kind of settings are there?
Field weakening?
some sort of salient control for ipm motors?

It looks kind of basic when it comes to connections, but it seems like you can connect a phone.
Does it work as a display, maybe even logger?

I asked qs about it, but the only response I got was basically that he didnt like the controller.

Might have to do with that I also asked questions about the 180 90h motor, so he just suggested the APT 96800.

Yes indeed :wink:
I don't know what to say, it is smooth, extremely powerful, plenty of top speed, so far it seems reliable, it's compact, doesn't seem to heat that much... I remember it was a bit difficult to set it up at first but it eventually worked.
Sorry my memory is a bit blurry since it's not my controller, I don't remember all the details.

He still has it installed on his bike, runs fine, no problem.
I believe he's not very active on the forum, but he's much more reactive on wechat, so if you have an account I can add you into our ebike group then you could ask him directly.
I'll try to ask him to check this thread tomorrow.

Not sure what you mean here. We used it on a hub motor, we don't have any inboard motor to test it.

I'm not sure because we tried lots of different controllers on his bike, kinda forgot.
I'm certain the Mobipus had that, but can't seem to remember how it works on the Nanjing Far.

I don't know why they say that, that's the best one I saw so far.

APT is supposedly a good brand, kebekua had one but unfortunately he never managed to make it work (despite many attempts), so can't say if it's any good. What I can say for sure is that the form factor is horrific, they are gigantic and very heavy.

Thanks, I dont have wechat. But if you could get him to write here would be nice.

Some sort of of compensation to get better efficiency and torque at low and mid range, especially on ipm motors.
In this clip it says MTPA on the screen, then it should have a really good system as far as I understand.

That, and the low battery amps is why I didnt go with them. (the low battery amps might be specific to the ones sold by qs it seems)
I already bought a sevcon for the yamaha, so I am not really shopping for a controller now.
But these look really interesting, so I sure get curious.
Maybe a backup plan, if I dont get the sevcon to work properly :wink:

The quality of Nanjing far driver controllers is still acceptable. You asked QS because they did not cooperate with FarDrive, so they do not recommend it for the sake of interest. The remote drive is more friendly to novices, and the debugging software is relatively simple and clear

I got some more info. It seems like max voltage on the 96V models is 118V, not 110V as it says on qs aliexpess site.
There is also a 1081200 :)
