Differences between V1, V2 and V3

 

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.

PS. for the same V1 steel/iron stator motors, QS Motor performance better on lifetime & stability becasue of good raw material. So the cost is more than normal hub motor in the market.
