Wind turbine is to become a wind power equipment. Wind round of thewind energy received a number of energy into electricity, relying on key motor. In the course of the electrical power generation is to fever, motor itself temperature will rise, the wind round received by the wind energy into two parts: the part of the electrical fever, the other part is power. Fever, have less power, the electrical efficiency is low.

For example, conventional 300 W wind turbine motor weight of the roughly 25 kilograms, hummingbird 350 W of electrical generators only the weight of five kilograms. Assumptions of conventional motors and hummingbird electrical power generation in the process of temperature rose to 80 ℃, then conventional motor heat at least a hummingbird motor five times. This is generating more hummingbird the reason.

Specific, for example: 300 W conventional wind generator motor and hummingbird wind have received 450 W round of the wind. Conventional electrical generating capacity = 450 W × 0.52 (conventional electrical conversion efficiency) = 234 W.

Hummingbird electrical generating capacity = 450 W × 0.8 (hummingbird electrical conversion efficiency) = 360 W.
