The polarity, and the adjacent second magnetic body 23 are of different polarities.

In the overall implementation, the inner diameter of the first rotating body 10 is larger than the outer diameter of the second rotating body 22, and the inner circumference of the first rotating body 10 is provided with a plurality of second rotating bodies 22, when the first rotating body is driven by the power component When the rotation is formed, the magnetic force of the first and second magnetic regions is used to form a coupling function, so that the first rotating body 10 and the plurality of second rotating bodies 22 can be simultaneously rotated, thereby causing the power generating element 21 to generate electricity, and The power output is for the user to use or store. The gap between the first and second magnetic intervals can be used to control the torque between the two, so as to control the rotation speed of the second rotating body due to the magnetic action, so that the rotational speed of the control power generating component can reach the set range, that is, If the power generated by the power component is large and the first rotating body rotates at a large speed, the second rotating body can also maintain a specific rotating speed without causing excessive current due to excessive rotation speed, causing the power generating component to burn. Moreover, the gap 30 can be adjusted to different sizes, but it is preferable to maintain the first and second magnetic regions not in contact with each other.

In addition, the difference between the magnetic interlocking shift and the general gear or belt interlocking shift of the present invention is as follows:

1. Gear linkage speed change: Due to the friction caused by the direct contact between the contact surfaces, about 8% of the efficiency loss, and friction noise will occur.

2, belt linkage shift: due to the friction between the belt and the roller caused by direct friction, about 5% of the efficiency loss, and the same will produce friction noise.

3. The magnetic interlocking shifting used in the present invention is that the magnetic force is not directly contacted, and the power can be transmitted without friction, and there is no loss of efficiency, and of course no noise; since no efficiency loss is applied to this. Energy generation or other bodies that require linkages can increase efficiency. Among them, conventional wind turbines, exercise bikes or electric vehicles, etc., often suffer from congenital instability (such as too much wind to make the power components rotate rapidly), the generator set is very easy to damage, if using the power generation device of the present invention , using magnetic linkage to produce shifting, you can avoid Unstable dynamics produce a loss of damage.

Although the present invention has been disclosed above by way of example, it is not intended to limit the invention. The scope of the present invention is defined by the scope of the claims, and the scope of the invention is intended to be limited by the scope of the invention.
