Voltage Other, 48V-96V

QS 12inch 3000W 260 (40H) E-Scooter Normal/V1 Type Hub Motor

When placing order, pls. advise below points:

1. Voltage, RPM or kV

2. Disc brake or drum brake

Thank you for your cooperation.

² Motor Spec

More pictures of motor: /sh/7mh2hs0kt85ulme/AAB0WFqvl7z5OL1nA38n_sIza?dl=0

²Speed Suggestion

The voltage we could be 48v, 60v, 72v, the max. speed can be customized to from 30 to 70km/h.

Rough calcuation formula of speed:

V=0.9*RPM*2πr*60/1000 V (KPH), RPM=un-load RPM, r=radius of tire

As Power=Torque*RPM/9.549, the more RPM is, the less torque it will be.

Tips: Please advise Voltage & RPM when placing order, If there is no marking, we will make it 72V 893RPM.

We suggest to choose Balance/2nd model for mass production, as the repair rate of high speed model will be higher.

²Controller Suggestion

The power of controller should ≥ power of motor.

For 12inch 260 3000W 40H motor(rated speed 30-70km/h), you could choose 60-80A(limited current) controller.

When you using overvoltage, then the max. speed increased sharply, the real power is not 3000w. The higher speed get for motor(overvoltage condition), the bigger limited current should choose for matched controller, when considering the starting acceleration capability and climbing performance.

If you don’t how to match controller, please don’t hesitate to contact with ue. We could also provide suitable controller.

Square Wave Controller: Kelly Controller KEB 72451

Sine wave controller: Sabvoton Controller SVMC/SSC072080 , Lingbo Controller LBMC072202.

²Motor Design of inner configuration

There are three types, Normal/V1 type (low cost), Export/V2 type (Cost-effective) and Extra/V3 type (Best Performance).

1. Comparison between V1 and 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. Comparison between V2 and 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/phase wire and thicker Cross-sectional area section, bear more current in usage. Magentic Steel: V3 is wider and thicker. Efficiency: 86~88%(V2) 88~92%(V3) Thus, V3 have best performance.

²Test Report

Here is 260 3000W V3 test report for reference.

²CAD Drawing

For 12inch 260 motor, we have 12x2.15inch, 12x2.5inch and 12x3.5inch for your choice. The inner configuration is the same, only different on the installation for your tire. So you can choose the wheel size according to your tire model. Take an example, if your tire is 90/90-12, then you can choose 12x2.15inch motor.

Anyhow, if you don't know how to choose it, pls. feel free to contact with us.
