QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

rather than adulterated (modified), it looks like it was cooked (probably a short between phase coils thru the stator laminations or directly to each other, possibly from nicks in the winding insulation during construction, or simply from overheating causing insulation failure)

You'd better added a temperature sensor

My 5kw QS survived 22kw during acceleration in my 180kg scooter. But only with upgraded phase wires and an added temperature sensor. Before I melted the phase wire Isolation.

Será mejor que agregues un sensor de temperatura.

Mi QS de 5 kW sobrevivió a 22 kW durante la aceleración en mi scooter de 180 kg. Pero solo con cables de fase mejorados y un sensor de temperatura adicional. Antes de que fundiera el aislamiento del cable de fase.

I'll have to read a lot in the forum then.
Can you share some winding link with me?

 

[dominik h]

Pictures from my two motors, no clue about windings.
Melted phase wires QS60V5000W
Now I have installed a QS10000W Motor and a Fardriver ND721800 and drive it with 400A line and 1400A phase current.
Added another 10kg to my scooter.

Well, since QS said it's the 4kw version, it appears that the entire 15000w engraving on there was added by someone between the time it left QS and the time it got to you.

That said, QS motors appear to be built better than a lot of others, and rated realistically for sustained power (many sellers/brands seem to be rated for *peak short burst* power), so short term they can take significantly more than that (some people have run the QS205 at 10kw+ for short bursts, though one of them sheared the axles off...partly a consequence of using just flatted axles for torque management instead of one of the several existing better solutions).

Any plans to make new hairpin SIA155-64 motor with gearbox?

 

[QSMOTOR]

Hello, currently there is no plan to make SIA155-64 motor with gearbox yet. The non gearbox version is available to order.

What value in kohms is the sensor?
Controler votol fardriver
What sensor did you use?

 

[dominik h]

I don't know which sensor are selectable in the votol Software.
I had used a 200k ntc as a 230k was not available and I have a Fardriver Controller. I later added a resistor so that the temperature is shown correct at 140C.

Hello, it's available to contact me directly or order it through our AliExpress Store named with SiAECOSYS.

How do I contact you directly?

 

[QSMOTOR]

Hello,my email is alan@siaecosys.com and my WhatsApp is +86-15905861560.

 

[Balgaroth]

Hi Alan, I have a question regarding the maximum load that a QS138v3 70h can take on its top support. Usually that anchoring point is used with the front motor mount of a motorcross bike to make a battery tray. It seems that my battery will sit right on top of the motor mount. So would it be a ok for the motor if the battery weight (27kg) was resting only on that anchoring point, or do I need to build a battery tray that would spread the weight on other areas of the bike ?

 

[QSMOTOR]

I don't recommend doing so. It is best to follow what you said above and build a battery tray to distribute the weight to other areas of the bicycle. These mounting points on the motor are originally designed to fixed with the frame.They are not suitable for bearing additional external forces.

Do you guys make a QS165-60 without a gearbox? Also do you know the rpm/volt for both the QS165-60 and QS165-50 and would you be able to sell me one with a different wind intended for higher voltages (104v)?

 

[QSMOTOR]

Hello, there is no QS165-60H without a gearbox version. The one without gearbox version is QS165-50 without gearbox. For QS165-60 with gearbox, it's 5400 RPM/72V=75 RPM/V. And for QS165-50 without gearbox, it's 6200 RPM/72V=86 RPM/V. If your battery fully charged is 104V, the QS165-60 and QS165-50 are avaialble to work under 104V. And pls consider to choose Encoder type QS165 motor. Any other question you have pls let me know.

 

[AdR]

@QSMOTOR-I have a 205/3Kw with double sensor wire set. How can I get wiring pinout.

 

[QSMOTOR]

Hello, pls find the hall sensor connector wiring definition for your ref.

 

[AdR]

Thx@qsmotor

 

[tonyinvents]

@QSMOTOR Can you please help me identify this motor by the markings? I bought this on alibaba as an "8kw bike". I want to upgrade the controller and battery but want to learn about the motor first.

 

[QSMOTOR]

Hello,it's QS205 3000W rated 50H spoke motor. The rated power is 3000W and peak power could go up to 8KW. It's suitable work with FarDriver ND72450 controller or EM150-2SP controller.
