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.
Brake: PCD6*44mm for e-bicycle disc
Spoke Hole: 4.2mm hole suit 8G/9G/10G spoke
Tips: Please advise the Spoke size & thread model when placing order, or we would make 4.2mm spoke & provide English Thread as default.
