²Controller Suggestion

The power of controller should ≥ power of motor.

For 205 800W motor(rated speed 30-45km/h), you could choose 33-35A(limited current) controller. 

Square Wave Controller: Kelly Controller KBS48121.

Sine wave controller: HY Controller 48v35A


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.
