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

Interesting thread!
 
Vito8828- Would it be possible to make your 70MM wide largest stator diameter hub-motor into a double-stator? I would need the windings terminated to be powered from 4x Sevcon size6 controllers, it would only need to handle having 240kW sent to it for ~7-8 seconds.

I want to hubmotor my Sparrow.

Do you sell compact sine wave controller? Something like 12 Fet controller 65A

Hello,

We cooperated with many controller manufactures in China, and are able to provide controllers.
For Sine Wave controller, Sabvoton and Lingbo controller is well known.
Also Kelly has developed some Sine Wave controllers in year 2014.

For compact sine wave controller, we are testing some small sine wave controllers.
Which might on sale after Chinese New Year.

Best Regards

Please share the compact controller for sale after new year, we need good compact controller and not these massive one that takes so much space

A 240kW chineese hub motor...

That's the Luke we know !! 8)
 
I saw that this company look like to have Lightning Motorcycles as client... I wonder if they built their motor or some of their parts.

This is the prototype for the 2 stator, dual controller, 63 kw hub motor. The prototype was built to test the design at 22 kw on the LRC motor scooter. The test is primarily to determine if the design delivers on longer range than lower power motors as paper studies show it should get. The LRC currently can run 140 miles on a charge at highway speeds. This motor is the format for the large Cruizer motorcycle in planning where it will be used at a planned 63 kw. Should the tests work as planned, the motor will become an option on the LRC scooter. In the production version the motor will be more narrow and lighter.

One of the most interesting specification for me is the motor weight. Can you make this information available ?

Thank you.
It's a pity that the weight is not complete as we have thousands of motors.
Could you please advise which motor do you prefer and I could get back to you accordingly.

E.g.
QS 3000W 205 Spoke Motor V3 Type, G.W./N.W. 14.0kg/12.8kg
QS 13inch 8000W 273 Hub Motor V3 Type, G.W./N.W. 24.0lg/22.5kg
 
\/ampa said:
From all three "BLDC Non Hubmotor" models.

Thank you. Here is the the weight of Qs 5000W 171 Built-in PMSM Brushless DC Motor firstly.
G.W./N.W. 16.0kg/14.8kg
For others, I have to check later and get back to you accordingly.

Thank you for sharing. We also work with ZEV in USA on hub motors. : )
Recently, they purchase a QS 13inch 6kW+6kW(45H+45H) dual stator hub motor V3 type for testing.

Thank you for your kindly information.
As checked, dual 70mm is too wide for normal motorcycle/car.
For the moment, we could make it 13inch dual 50mm stator doulbe-shaft hub motor or 273 dual 50mm stator e-car hub motor.
Generally, the peak power for one 50mm hub motor is 20kW for few second.
If any question, please feel free to contact with us.
 
Hello
i was looking for some information on your hub motor 12" 500W 205 28H Export type/V2 Electric Scooter Hub Motor, i've looked in website and did not find any of these.
- moment of inertia
- Ld and Lq
- Self inductance and mutual inductance.
- back emf constant.
Is it possible to get them ?

Best regards.

Vito, in your experience.. do you notice a difference in efficiency between sine wave and square wave controllers?

In my point, there is a little difference in efficiency between sine wave and square wave controllers.
Sine Wave might be a little bit higher efficiciency.
Please refer to attached two test report for same motor, as you can see.
Sine Wave: 93.5%, Square Wave: 93.0%

Best Regards

what type of motor this is exactly?
that graphs looks to good to be true (at least for a single 205 / 50mm type motor) :)

edit:
i mean this http://tzquanshun.en.alibaba.com/pr...00W_205_Electric_Bike_Spoke_Hub_V3_Motor.html
