PS. 1. Above quotation base on 205 electric bike spoke hub motor.
2. For 205 motor, the voltage is 48V~96V.
3. Above configuration is suggested for mass production,
for EV enthusiast, V2 & V3 motor could be over-voltaged to gain more speed (customizable).

For the max continuous power rating
The data should be tested in lab, which means no further temp rise at the power (e.g. 100 degree inside of motor at the power).
Unluckly, all the continuous power rating is not done before.

Due to our understanding and feedback of customer,
for 205 3000W motor, the max continuous power could be 6000W, peak power 12kW (even 18kW).
For EV enthusiastic, they could input more power to enjoy the high performance, but the motor might suffer from over heating or even burnt.
For EV Manufacture, we should notice the potential performance of motor, and keep some allowance for the whole e-scooter kits.
include motor, controller, battery. to get them as stable as possible & decress the repair rate (consider all the usage environment).
E.g. 3000W as continuous rating power.

For samples, "QSMOTOR" logo is laser print on side cover as default.
Meanwhile, the logo could be customized with below essential document.
· Please provide high definition logo in jpg format.

How to find suitable hub motor
To customized a suitable motor, could you pls. inform below points:
1.E-scooter, E-tricycle or E-car, tire model?
2.Volt and wattage of motor, Speed(kV), and torque/climb angle ?
3.Your vehicle weight and loading weight?
4.Lithium or lead-acid Battery?
We could suggest most suitable motor accordingly, thank you for your cooperation.
PS. To calculate the speed, v(km/h)=n(r/min)*2rπ(m)*60/1000, n=load RPM, r=tire radius.
For speed less than 100KPH, consider the Windage Resistance & Rolling resistance.
the load RPM is appr 0.9 * no-load RPM. v(km/h)=0.9*n(r/min)*2rπ(m)*60/1000
For over 100KPH, V=0.85*RPM*2rπ*60/1000

Electric Motor Kits
After confirming the motor, we could try to offer suitable motor kits, e.g. controller, wheel set, charger, speedometer,
throttle, brake, DC-DC converter, etc.
PS. So far, the battery is not avaiable.

QS Motor V1/V2/V3 Type Motor
There are three types, Normal/V1 type (low cost), Export/V2 type (Cost-effective) and Extra/V3 type (Best Performance).
图片3.jpg
QS Motor V1 V2 V3
图片3.jpg (124.62 KiB) Viewed 22801 times

1. Difference between V1 & V2
Holder: Iron(V1), Aluminum (V2)
Hall: One hall with Normal connector(V1), Two halls with Waterproof connector(V2)
Stator: V2 have a stronger configuration, more cooper, thicker section surface, energy saving in usage.
Magnetic Steel Grade: V2 ≥ V1
Efficiency: 84~87%(V1) 86~88%(V2)
In short, normal type is standard configuration, while export type is high configuration.The price differs because of the cost of raw materials.
2. Difference between V2 & V3
The raw materials are alike, main difference in inner construction.
For V3 (16 Pole Pairs): stronger configuration than V2, wider lamination,
more cooper wire /thicker Cross-sectional area section, bear more current
in usage. Higher torque at same current, lower temperature rise, more stable in high current.
Magentic Steel: V3 is wider and thicker.
Efficiency: 86~88%(V2) 88~92%(V3); Thus, V3 have best performance.
PS. for the same V1 steel/iron stator motors, QS Motor performance better on lifetime & stability becasue of good raw material. So the cost is more than normal hub motor in the market.
E.g. 1. Choose C&U bearing which is motorcycle standard, more quiet when riding.
2. High Coil space factor, better efficiency.
3. Silicon steel sheet 0.35mm instead of 0.5mm, less current consumption & low temp rise.
4. Insulation varnish outside of varnished wire, max 180 ℃ than normal 120 ℃.
5. Better magnet, demagnetizing less than 1% than normal 3%.

QS Motor Steel Seal
We could laser print it on side cover or edge of side cover.
For V3 type motors(e.g. WP20040X140607 7355)
WP= V3 type 200=2000W, 300=3000W
40 means winding X means 32 pieces magnetic steel
140607 means producting date, 07th, June, 2014. 7355, is producing serial number

For V2 type motors(e.g. QSMOTOR 48V3000W 140720 604329)
48V3000W=48V 3000W 140720 means producing date, 20th, July, 2014.
60 means rated speed, 60km/h. 4329 is producing serial number.
P.S.: We define power base on rated output power, rather than peak output power.

How to make the order
·Before-sale, please advise which motor do you prefer, and advise above expected configuration of EV if possible.
After confirming motor, we could also advise suitable motor kits (e.g. controller).
It could be paid online, e.g. QS Motor Shop on alibaba, aliexpress;
We suggest to make the deal offline, we will make PI accordingly (latest price & accurate delivery cost).
·In-sale, we will informe you once received the payment to start the order & ETD.
Before delivery, we will send some pictures for reference.
·After-sale, Once got the tracking number, will informed you immediately.
Manual and software will be sent accordingly, also we will email you after the package delivered.

Payment Term
Wire Transfer/TT, Money Gram,Western Union, Paypal 100% in advance(for sample)
Generally, we perefer T/T, Money Gram,Western Union 100% in advance (for sample).
Meanwhile, we could also accpet paypal. There will be extra cost for transaction fee: Total cost*4.4%+0.3
Withdraw fee: USD 35.0 (We could bear USD 35.0).
For Mass Production, we support 30% T/T in advance + 70% T/T the balance before shipment.
Produce Time
For normal motors, e.g. e-scooter motor, e-motorcycle, it takes 10-12 business days (6 business per week).
For customzide motor & single shaft motor, it takes 15-16 business days.
In busy season, the order might be postponed. For mass production, the produce time will be increased accordingly.
PS. For the 3000W 205 50H V3 spoke hub motor, we made some 24*5T & 30*4T motor in store.
Package
Standard export packing 1. polyfoam + carton box (for sample) 2. Or according to customer's requirements

Life Time of QS Motor & Warranty of Sample
The Life Time of motor depends on usage.
For general usage, it's about 3-5 years, and it could be 5-7 years if it work in good condition.
For testing and abusing usage, the lifetime will decrease accordingly.
E.g., For 3kW V2/V3 motor, the peak power could be 6kW (2 times of rated power).
Situation 1:
We suggest peak 70-80A battery current for general usage (72V). It's most stable configuration & longest life time.
Some EV enthusiast adjust it to be 150A, the output power is far more than 6kW peak. QS Motor could also work,
which might not as stable as former situation. For a long time in high current/power, the motor might over heat & even burnt.
We strongly suggest to install Thermic Probe (e.g. KTY 83/122), so that controller will protect motor due to the temp inside of motor.
Situation 2:
The peak speed of 1pc 3kW motor is 80KPH in 72V(for e-scooter).
Some EV enthusiast adjust it to be 96V, the max speed might be 100KPH, the continuous output power is far more than 3kW rated (maybe equal to 5-6kW).
QS Motor could also work, which might not as stable as it in 72V.
We call it over voltage/abusing usage, the life time might be shorter, and V3 will work better than V2.

Warranty period: one year and three months (sincethe date of manufacture) or after riding 15000KM.
For Sample, If it's destructive test/abusing usage due to test purpose, we could not do aftersale issue for free.
If there is some damage during your test, which we could repair.
After checking your video or pictures, we could deliver some motor parts (e.g. hall sensor) for maintenance.
Also, you could deliver them back to our factory(I'm afraid that you have to bear delivery fee, both way),
We will make maintenance as possible as we could. For repair fee, we could bear the cost for 1 year.

For this type motor, the wheel is separated with motor, when there is damage on the wheel rim,
you only need to replace the wheel rim from your vehicle and no need to remove the motor, which is more simple and low maintenance cost.
Here is video of this motor for your reference: http://v.youku.com/v_show/id_XODA5ODQ2ODgw.html

Thank you for your time to reading.

For Electric scooter/motorcycle motor
We produce 10"/12" 205 motor from 1000W~3000W, and 13"~17“ 273 motor from 3000W~8000W.
Our greatest motor is Qs 8000W 273 (50mm magnet height) hub motor extra/V3 type
http://tzquanshun.en.alibaba.com/product/60082173269-800325938/13_8000W_273_50H_Extra_type_V3_Electric_Scooter_Hub_Motor.html
8840W continuous, 11245W peak @ 72V 200A, which might also call it 10kW.
N.W. 23~24kg, maximum 800~1500RPM, 200-300N.m.
For 8kW V3 motor, we suggest peak 150-200A battery current for general usage (72V). It's most stable configuration & longest life time.
Some EV enthusiast adjust it to be 350A, the output power is far more than 8kW (maybe 17-19kW). QS motor could also work, which might not as stable as former one.
For a long time in high current/power, the motor might over heat & even burnt. We strongly suggest to install Thermic Probe (KTY 83/122),
so that controller will turn off when it's 120°C inside of motor.
Also. another costomer make it 96V battery, 400A peak phase current, 19kW output.
We call it overvoltage usage, the life time might be shorter.

Meanwhile, dual stator hub motor 2*3kW, 2*8kW could be customized.

One of our customers assembled a scooter which used Qs 13inch 72v 8000w (50mm magent height) extra type/V3 motor (maximum 1405RPM in 72V, 200N.m)
After testing 10000km, the motor works perfectly, max speed could reach more than 120km/h.Moreover, our motor don't go over 60 Degree even he use 350A (battery 350A maximum, 290A continuous, 89V fully charged, 21s Lipo).

Re: QS 500W-10kW BLDC In-Wheel Hub Motor Catalog (Manufactur

Postby riba2233 » Tue Jan 13, 2015 9:27 am

What is the weight of 17inch Hub Motor (2kW-8kW) ?

Also 3-5 years seems kind of low for life expectancy.

And one comment about dual stator motors - why not just make one stator that is double the width? You would have much less end turn wire losses, and you would use volume better.

Thank you for your questions, the weight of 17inc 8kW hub motor is 26-26.5kg (G.W.)
For Life expectancy, Our motor could work 5000 hrs without damage in Lab.
While riding, the life time of motor depends on motor's usage (e.g. hitting, watering).
Moreover, the design of dual stator motor is finally determined considering many issues.
For one stator, we could make the magnetic steel maximum 70mm, which is rated 12kW for e-car hub motor.

Please note: Consider the high current for 12kw motor, we make six phase lines, while you should connect the two same color phase lines with accordingly wire of controller.
                       i.e.: connect the yellow phase line of controller with two yellow phase line of motor. 
                              connect the blue phase line of controller with two blue phase line of motor. 
                              connect the green phase line of controller with two green phase line of motor. 
P.S.: for one phase line, the cross section area is 12mm², so for two phase line, the cross section area is 24mm².

Vito, I have questions about the 3-5 year lifetime. What steel are you talking about? Do you mean the permanent magnets?

I don't want to hijack your for-sale posting with technical questions, so could you go to this thread and answer them?

Just want to chime in re: iron losing its performance - its bullshit. Same for the magnets, they do not degrade.

I guess the reason for the 3-5 year statement is that moisture ingress slowly corrodes the stator.

One tip: better pictures.

Hello Dougt, Thank you for your interest in QS Motor.
Here is my comment below about life time for reference only.
The life time of motor depends on usage.
For general usage, it's about 3-5 years, and it will be 5-7 years if it work in good condition.
For testing and abusing usage, the lifetime will decrease accordingly.
Btw., Our motor could work 5000 hrs without damage in Lab.

Here is the main points below.
1.Moisture ingress slowly corrodes the stator & magnet, the parts will get rust and lead to other issues (E.g. electric leakage)
Vito: We will place waterproof glue sealant on edge of the rim of the motor, and around the wires coming out of the motor by the stator.
Then the motor will be IP54, which means the motor can work in raining day (even heavy rain), and can drive through the puddles/mud, but can't work under the water completely.
Moreover, for V2 & V3 type motor, we choose waterproof connectors.

For QS Motor, we paint transformer oil on cooper and magnetic steel to keep from moisture and rust. And now, we are testing to put some mineral oil for better performance.

2. High Configuration abusing motors (high input power), which lead to heat issue.
And demagnetize partially or completely.
Vito: We choose NdFeB with different grades. It might be demagnetize in high temperature (e.g. 120°).
For QS Motor, we install temperature termo resistor/Thermic Probe inside of stator.
When it reach 120°, controller will turn off.

3.Mechanical reason (e.g. Axle, bearing)
Vito: We choose 40Cr-HRC28 for axle, which is strong enough for general usage.
For bearing, here is list of single-shaft motor below.
No. Name Item Parameter Note
1 6204 Bearing Bearing capacity  Cr=13.50KN   COr=6.55KN  
2 6009 Bearing Bearing capacity  Cr=21.00KN   COr=15.10KN Disc Brake Side
Btw., laminations is made of silicon steel.

Thank you for your time, there might be something wrong due to my limited knowledge.
You could test one QS Motor for better understanding if possible.

Vito this is very exciting, I downloaded your PDF brochure and it is much clearer in information than the Alibaba website!

I am building my own custom scooter and would want to upgrade to a new motor and controller in the future to be the same as your customer who built his own bike with your motor as you posted. The 13" 8000W V3 motor would be perfect with a high output Kelly controller or equivalent.

I will email you in time.

These motors sound great. I appreciate the fact that the company comes on here and is very very open with technical specifications..

It is rare that a company understands how us DIY builders think.. :)

The cast wheel hub motors are amazingly beautiful too!! what a shame that they are only available for 16 - 20" rims..
My first major build: 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w on a Turner O2 full suspension.
The wheelie machine: 20" Rear Magic Pie II on a Trek 4300 MTB

Thank you for your comment, we communicate with many customers.
We always thought on Customer's point of view, and try our best to meet your requirement.
Meanwhile, most of demostic DIY team purchase from QS Motor directly.

For 16-20" rim, I think it's e-bike standard.
We also could make 16-20" wheel motors (500W-1500W).
But mainly, we focus on e-scooter standard wheel motor (500W-8000W).

If any question, please feel free to contact with us.

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.

Vito, in your experience.. do you notice a difference in efficiency between sine wave and square wave controllers?
My first major build: 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w on a Turner O2 full suspension.
The wheelie machine: 20" Rear Magic Pie II on a Trek 4300 MTB

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
