Really sorry we could not provide the 3D CAD drawing for the motor, it is related with our business secret.
But if you bought the motor from us, and really need it, after we sign NDA, we can provide it to you separatelly.

Thank you,
Judy

Your engineers could simplify the 3D model (no need to show internals) and export it as STL file. I'm guessing the 3D model would only be needed to design mountings and other related items on e-vehicle, so only external dimensions matter.
You do have 2D drawings (but one has to be very persistent, trying to find those) of your motors, showing external dimensions, so it's not that big secret.

Isn't there software by now that can take those three and produce a 3D model?

Hi QSMOTOR,

Do you have a bracket for the model QS138 70H v3 to mount on a regular bicycle?

If Not, I will have to design and cut one but I have no idea how I will do that. I even dont know how to use 3D modeling.

I hope you can help me.
Thanks

Hi any news about the new mid motor 180? Your website has shown the motor for more then a year but still not possible to buy.

1: Do you know if that new 180 series will be ready this year in 2020?

2: Iirc you last year said something about making the 180 motor with different power output. From QSMOTOR 180 90H up to QSMOTOR 180 135H, is that correct? Would like to know continuous and peak for both of those.

3: If your motor is still in beta testing, possible to buy a beta version? I don't care about warranty, and I can put that in writing for you if like.

Now this 180 8kw 90H mid drive motor is available now.
The unit price is $673/pc
The continue power is 8kw, peak is 16kw, it is encorder board, not hall.

The motor is available now, just for matching the controller it is still testing.

Thank you,
Judy

Is the new QS 180 90h available with a 428 sprocket? Or do the 138 sprockets fit on the 180 shaft? Which controller will be best for the Motor?

The new 180 90H we are going to use 530 sprocket, when we ship the item we will match the 530 sprocket well.
138 sprocket does not fit 180 shaft, the size is different.

The controller we are considering is ND721200 or ND721800, still testing.

Thank you,

Why use a 530 sprocket?? Even a 520 would be overkill, a 428 chain and sprocket should be the absolute maximum for this Motor, everything else is just more drag and weight. Will you offer 428 sprockets that fit this shaft, or maybe a belt driven system?

520 or 530 both ok, but 420 worry it could not bear so powerful.

For now, only sprocket type available.

Anyone have experience with running any of the QS motor with fardriver controllers? Any bad experiences?

Now we are trying to build our warehouse in European market, that the main purpose is to lower down the shipping cost.
…

Hi
Any updates on the warehouse in the European market?
High shipping costs is a major deterrent for me and probably many other potential customers.

 

[999zip999]

USA needs a warehouse.

 

[QSMOTOR]

Anyone have experience with running any of the QS motor with fardriver controllers? Any bad experiences?

Until now for our own testing, we think far driver is more stable than VOLTA controller.
