Wind power generator for small wind energy plant, has cooling body with large surface arranged inside continuous massively designed fixed axial pipe, and flowing nozzle arranged on side turned to spinner

摘要

The generator has a stator (2) arranged on a continuous massively designed fixed axial pipe (3) whose length is equal or longer than length of an external rotor (1). The fixed axial pipe is elongated in one side or two sides. Multiple continuous cooling channels (17) with large surface are arranged inside the fixed axial pipe. A cooling body (6) with large surface is arranged inside the fixed axial pipe. Length of the cooling body is equal or larger than length of a stator lamination stack (5). A flowing nozzle (11) is arranged on a side turned to a spinner (10).
