ROTARY BLADE WITH SHROUD HAVING SEAL THAT CAN ELIMINATE MINUTE MAGNETIC MATERIAL ADHERING ON PERMANENT MAGNET AND MAINTAIN GAP BETWEEN ELECTROMAGNET AND PERMANENT MAGNET, AND WIND POWER GENERATING DEVICE USING PERIPHERAL VELOCITY

摘要

PROBLEM TO BE SOLVED: To eliminate a minute magnetic material adhering on the acting face of a permanent magnet of a device comprising an electromagnet and a permanent magnet used in a wind power generating device electromagnetically using a rotary blade having a shroud used for flying and peripheral velocity and to maintain a gap between the electromagnet and the permanent magnet, with a simple and inexpensive device.

SOLUTION: The minute magnetic material adhering on the permanent magnet of the device comprising the electromagnet and the permanent magnet used in the wind generating device electromagnetically using the rotary blade having the shroud for flying and peripheral velocity can be eliminated by adhering a detachable seal on an arrangement face of the permanent magnet, and the gap between the electromagnet and the permanent magnet can be maintained by making the material of the seal with a material low in the coefficient of dynamic friction with the simple and inexpensive device.
