Cooling Structure
Latest Technologies
New ventilation system for larger output
The latest analytical technologies applied, achieving an optimal cooling system that suppresses temperature rise throughout the generator and realizes higher generator output.
CFD analysis
Higher efficiency fan for lower windage loss
A small, high efficiency propeller fan is incorporated to ensure that required fan characteristics are realized, sufficiently reducing wind loss and realizing a high efficiency generator.
