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.

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.

Performance Curve and Drawing
The performance Curve & drawing are available. E.g. 10"X3.0" 3kW V3 type Hub Motor.
There is 300N.m dynamometer, which is avaialbe for general double shaft hub motor.

PS. We're manufacture, there is no spare motors in store generally.
Standard export packing 1. polyfoam + carton box (for sample) 2. Or according to customer's requirements

Life Time of 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.

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 price
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.
