QS 205 50H V3 3000w electric bike motor 80km/h extra type
QS / Quan Shun, 205/50H V3 "Extra Type"
The QS motor company has also decided to begin selling their E-motorcycle hubs with axles that that have been modified to fit a bicycle.
Their motor phase wires are thicker than the other motors listed, and their axle design is stronger.
The stator width is 50mm, but also…the stator-teeth slots are deeper for more copper-fill, and all of this adds up to a motor that can take more watts.

For Drawing.
Standard Drawing
QS support Customized, the axle could be customized accordingly (the cost and delivery time will increase).
For example,
Customized axle, 155mm dropout, USD 8.0/piece more, take 7-10 days more for customized axle.

Note: QS Motor could work 120 ℃ in half an hour without damage.
Conservative Suggestion (Setting of Controller)
When it's 130 ℃ inside of motor (in 30s), the current should be limited 50%.
When it's 150 ℃, the controller shut down.
When it drop down to 110℃, the controller work again.
Suggestion Controller
Most Customer choose Adaptto MAX-E controller, but I have little understanding of the controller.
Some customer ask me about the correct setting, I will try my best to get it.
Meanwhile, could you please help me out and advise some information on this?
Buying Guides
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

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.
