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.

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).
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;

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.
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.

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.
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).
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.
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.
