The output power of this DC motor is related to the magnetic force of the magnetic poles and the rotation force. If the maximum induced voltage between a magnetic pole is 100 V, it corresponds to the force of wind airflow over the fan blades. If the wind is weak, the suction force of the magnetic pole cannot rotate, so the magnetic field lines cannot be cut. And if the wind gets stronger, it will speed up the rotation. Quickly return the induced voltage cycle to the next induced voltage cycle. As frequency increases, duty cycle time decreases. Power is increased. The duty cycle is formed by the space in the middle of rings A and B.

(2) Suppose that the conversion constant between wind energy and the output power is k, then:
The wind turbine can produce electrical energy at wind speed v 1:
P 1 =kPm=

The electrical power that the wind turbine can produce when the wind speed v 2 is :

So,
