QS 10inch 2000W 205 (50H) E Scooter Normal V1 Type Quanshun Motor Hub Motor

Product Overview

Description

QS 10inch 2000W 205 (50H) E-Scooter  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 

 

 

 

 

²Speed Suggestion

The  voltage we could be 48v, 60v,72v, 96v, the max. speed can be customized to from 30 to 60km/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 850RPM.

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 10inch 205 2000W motor(rated speed 30-60km/h), you could choose 50-60A(limited current) controller. 

When you using overvoltage, then the max. speed increased sharply, the real power is not 2000w. 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 KEB72451X,

Sine wave controller: Sabvoton Controller SSC72080 / SSC72080 & Lingbo Controller LBMC072181.

 

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.

²CAD Drawing

  

For 10inch motor, we have 10x2.15inch and 10x3.0inch 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 3.00-10, then you can choose 10x2.15inch motor.

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

²Motor Kit 

We could provide suitable controllers, freewheel, brake disc, throttle etc.

For the moment, we could not provide wheel set & Spokes.
