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 riding15000KM.
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.
